Convert PDF to EPUB Portable Document Format ↔ Electronic Publication Free Online Secure
Your PDF is read here in your browser and written out as EPUB. A PDF records where each letter sits, not what it means, so the headings, paragraphs, lists and tables are worked out from position and size — and you get something you can edit again, not a picture of a page.

Where these formats come from
An EPUB is, underneath, a zipped website: pages of HTML with a stylesheet and a table of contents. That is why text in an e-book reflows — the reader chooses the type size and the words rearrange themselves, exactly as they do in a browser window. MOBI came from Mobipocket, a French company Amazon bought in 2005; it became the first Kindle format and was retired by Amazon in 2022 in favour of EPUB. The contrast with PDF is the whole story of this family: a PDF holds fixed pages, laid out once and never moved, while an e-book holds text that has no pages until a reader opens it.
Where you meet them
EPUB is what every e-reader except the Kindle expects, what public libraries lend, and what most publishers produce. MOBI is for older Kindles and for archives of books bought before the change. Converting a PDF into either is the usual way to get a report, a manual or an out-of-print scan onto a reading device where the text can be made larger.
Questions people ask
Why does my PDF look messy after converting to EPUB?
Because the two work in opposite ways. A PDF knows where every word sits on a fixed page; an EPUB has to be told what is a heading, what is a paragraph and what order it all comes in, and none of that is recorded in a PDF. The converter infers it from position and size, and does well with plain single-column text. Two columns, footnotes, headers repeated on every page, tables and figures with captions are where the guessing shows, and they usually need tidying by hand.
Should I still use MOBI?
Only for an old device that cannot read anything else. Amazon stopped accepting MOBI for sending documents to Kindle in 2022 and now wants EPUB, which modern Kindles handle directly. If you are choosing today, choose EPUB: it is the format libraries lend, publishers produce and every reader but the oldest understands.
Does the file lose quality?
It depends on what the two formats can hold. Converting between formats that store the same thing — a PNG to a BMP, a WAV to a FLAC — loses nothing. Converting into a format that throws information away to save space, such as JPEG or MP3, loses a little every time, and converting back does not bring it back. Where a choice exists, this page errs towards keeping the original quality rather than making the smallest file.
Is my file uploaded anywhere?
No. The conversion happens inside your browser, on your own machine; the file never leaves it and there is no server here that could receive it. That is why a large file is limited by your own memory rather than by an upload, and why nothing you convert can appear in anybody's logs — including ours. The audio and video tools do fetch their conversion engine from this site the first time you use them, some thirty megabytes once; after that the work still happens entirely on your machine.
Why people convert PDF to EPUB
A PDF is a page, and a page has a fixed size. That is wonderful for a contract and miserable for a novel on a phone. On a small screen you have to zoom in, drag the page sideways and zoom out again to find your place, and the text never settles into something comfortable to read. An EPUB is the opposite kind of file: it holds the text as a flow that the reader program fits to the screen, so the lines break where the screen ends, the type can be made larger or smaller, and the book looks right on a phone, a tablet or a dedicated e-reader. That is the whole reason to convert PDF to EPUB: you want to read a long text comfortably.
The people who do it are easy to picture. Someone who downloaded a book or an article as a PDF and wants to read it on an e-reader. A student with a stack of papers who prefers to read them on a tablet in the evening. A reader with poor eyesight who needs large type. A writer who wants to proof a manuscript on a device that is not a computer. In each case the words matter and the page layout does not.
This page converts PDF to EPUB in your browser. Your PDF is not uploaded to a server, which matters for manuscripts, study material and anything you would rather keep to yourself. Below you will find how it works, what comes across, what does not and how to make the best of the result.
How the conversion works
The structure is worked out from the page
A PDF records where each letter sits, not what it means. There is no stored notion of a heading, a paragraph or a list. Your PDF is read inside your browser, and for each page the converter collects the text with its positions and sizes, and decides what is what. A larger line is likely a heading. Lines that follow one another with an ordinary gap form a paragraph. Rows that begin with bullets or numbers form a list. The result is written out as an EPUB in which those headings, paragraphs and lists are real elements.
Reflowable text
The text is stored as reflowable text, so it reads properly at any type size on any reader. This is the whole reason for converting a PDF to an e-book in the first place. Make the type larger and the lines re-break; switch to a narrow phone and the text fits the width. Nothing needs zooming or dragging.
Why this is better than a PDF on a small screen
A PDF page is a picture of a printed page. On a six-inch screen, a full A4 page is shrunk until the letters are tiny, or magnified until you see a quarter of it at once. A reflowable file has no page to shrink. It adapts to the screen you are holding.
What is kept
Headings, paragraphs, bold and italic
Headings, paragraphs, bold and italic are carried across. The text reads in the same order as on the page, and emphasis is preserved where it can be recognised.
Lists and tables
Lists come out as lists, and tables come out as tables, so the structure of the document is not lost on the way to the reader.
Pictures
Pictures are carried over and embedded in the EPUB, so the file is self-contained.
A file that opens in the common readers
EPUB is the standard e-book format. It opens in most e-readers and reading apps, on phones, tablets and computers, and Kindle takes it as well.
What is not carried over
The book arrives as a single chapter
The book arrives as a single chapter with one entry in its table of contents. A PDF does not record where its chapters begin, and guessing from headings would be wrong often enough to be worse than not guessing. You will therefore not find a chapter menu in the reader. You can still scroll or turn pages through the whole text, and your reader will remember your place.
Layout, columns, headers and footnotes
Page layout, columns, headers and footnotes are dropped. The running header at the top of each page, the page numbers and the footnotes at the bottom have no meaning in a flowing text, and they are not carried across. A page set in two columns comes out with the columns interleaved, because the lines are read across the page as they sit. If your document has columns, expect to see them mixed.
Scanned PDFs yield nothing
A scanned PDF holds a picture of text, not text. From one of those, nothing comes out. Recognising letters in an image is a different job, called optical character recognition, and this conversion does not do it.
How to convert PDF to EPUB here
Add your PDF
Drop the PDF onto the page or pick it from your device. It is opened inside your browser and is not uploaded.
Convert
Press the button. A short document takes a few seconds, and a long book takes longer. Leave the page open until it finishes.
Download and open
Download the EPUB and open it in your reading app or send it to your e-reader. Read the first pages and make sure the text flows as you expect.
A closer look at PDF and EPUB
Fixed and flowing
A PDF is fixed: the position of every letter is part of the file. An EPUB is flowing: it states what the content is, and the reader decides how to lay it out. These two ideas are almost opposite, which is why a conversion from PDF to EPUB has to rediscover the structure that the PDF never recorded. When it works well, the result feels like a book made for your device. When the source is untidy, it can feel like a long stream of text, and that is the honest outcome.
What makes a PDF convert well
A plain text document with ordinary paragraphs converts cleanly: a novel, an essay, a report. A document designed with sidebars, text boxes and multiple columns converts poorly, because its reading order is a matter of design, not of text. When you convert PDF to EPUB, prefer books and articles to magazines and brochures.
E-readers and apps
Most readers let you choose the font, the size of the type, the margins and the spacing between the lines. That is the point of the format. Spend a minute setting the page to suit your eyes, and the book will become a pleasure to read.
Common situations in detail
Reading a book on an e-reader
A book you hold as a PDF can be turned into something an e-reader handles well. Convert PDF to EPUB, send the file to the device or open it in an app, and the text fits the screen at the size you choose.
Studying on a tablet
Lecture notes, papers and manuals read better as reflowable text on a tablet. Sentences are easy to follow, and you can enlarge the type without scrolling sideways.
Accessibility
Readers with weak sight benefit from large type, high contrast and the option to have the text read aloud by the device. A reflowable file makes all this possible, while a PDF often resists it.
Proofreading a manuscript away from the desk
A writer who exports a manuscript to PDF can turn it into an EPUB and read it on a phone, on the train or in bed. Seeing the text in a different shape often reveals errors that the eye skips on the screen where it was written.
Practical advice before you convert PDF to EPUB
Test whether the text can be selected
Open the PDF in any viewer and try to select a sentence with the mouse. If the words highlight, the file holds real text and you can convert PDF to EPUB with good hope. If you can only drag a rectangle over the page, it is a picture, and no conversion of this kind will find words in it.
Choose a simple document
Novels, essays and articles work best. For documents full of tables and illustrations, an EPUB may not be the right container, and keeping the PDF is wiser.
Extract what you need
If you want only a part of a long document, use extract pages from PDF first. A shorter document converts faster and is easier to check.
Check the first and last pages
After you convert PDF to EPUB, look at the beginning and the end. Running headers and page numbers that slipped through are easiest to spot there, and you will know whether the rest deserves a closer look.
Questions people ask before converting
Why is there only one chapter?
Because a PDF does not record where its chapters begin. The book arrives as a single chapter with one entry in its table of contents. You can still read it from start to finish.
Why are my columns mixed up?
Because the lines are read across the page as they sit. A page set in two columns comes out interleaved.
Will it open on my Kindle?
Kindle takes EPUB now, so you can send the file to your device or open it in the app. For older devices that need the old Kindle format, there is PDF to MOBI, though EPUB is the better file.
Why did nothing come out?
Almost certainly the PDF is a scan. A scan holds a picture of text, not text.
Is my PDF uploaded?
No. The conversion runs in your browser and the document never leaves your device.
Can I go back to a PDF?
Yes. EPUB to PDF turns an e-book into a PDF again.
Choosing wisely when you convert PDF to EPUB
Decide whether you need an e-book at all
If the PDF reads comfortably on your device already, leave it as it is. The conversion is worth doing when the PDF is hard to read on a small screen.
Start with the cleanest source you have
A PDF exported from a word processor converts far better than a scan or a copy of a copy. If you can ask the author for the original text, do so.
Keep the PDF
The PDF holds the exact layout and the page numbers. Keep it as your reference, in case you need to cite a page.
Getting a good result after the conversion
Set the reader to your taste
Choose the font, the size and the margins that suit you. A small adjustment changes the experience entirely.
Ignore stray page numbers
If a page number or a header slipped into the text, it is harmless, and you can skip over it. For a book you will keep, you may want to clean it with an e-book editor.
Add the book to your library
Give the file a clear name, with the title and the author, before you send it to the device. Library software uses the file name when it cannot find anything better.
Reading comfortably after you convert PDF to EPUB
Pick a restful type size
The point of the format is that you decide how large the letters are. After you convert PDF to EPUB, spend a minute with the reader settings: raise the size until you stop leaning towards the screen, and choose a font with clear shapes. Long reading sessions are much easier when the text is not a strain.
Use night mode in the evening
Most reading apps can show light text on a dark background, or a warm tint. In the evening it is gentler on the eyes, and an EPUB takes it without any extra work, which a PDF page with its white background does not.
Take notes and highlights
Readers let you highlight a passage and add a note. For study, this is a real advantage over scrolling through a PDF: your marks stay with the text even when you change the type size.
Privacy and handling
Why local conversion matters for books and papers
Manuscripts, study material and private documents are not things you want sitting on a stranger's server. Many online converters upload your file, process it and send back the result, and for a while a copy lives on a machine you do not control. Here your own browser does the work, so the document stays on your device.
What happens when you leave
When you close the page, the converted file disappears from the browser, so download it first. Nothing about your document is kept.
If something goes wrong
The text has odd line breaks
This happens when the PDF was set with hard line breaks. An e-book editor can join the lines, or you can read it as it is.
The page freezes with a large book
Everything runs on your device, and a long book needs memory. Try again on a computer, or convert the book in parts.
The PDF is password protected
A protected document must be opened with its password first. Without it, the text cannot be read.
Related tools
The same family of tools covers the neighbouring jobs. For the older Kindle format, PDF to MOBI works in the same way, and MOBI to PDF goes back. For text you want to edit as a document, there is PDF to DOCX, and for a web page, PDF to HTML. When you want pictures of the pages instead, PDF to PNG is the answer.
A worked example
Say you have downloaded a short novel as a PDF of 180 pages and you want to read it on your phone during the commute. You drop the PDF here and press the button. A few seconds later you download an EPUB. You open it in a reading app, choose a comfortable font and size, and the text flows to the width of the screen. The book arrives as one chapter, so you set a bookmark where you stop, and the PDF stays in your folder as the original.
A short checklist
Before converting
Check that the PDF is not a scan. Decide which pages you need. Keep the PDF safe.
While converting
Stay on the page until the file is ready.
After converting
Open the EPUB, set the font and size, read the beginning and the end and name the file clearly.
Common mistakes
Expecting chapters
Do not convert PDF to EPUB expecting a chapter menu. The book arrives as a single chapter.
Choosing a magazine
Heavily designed documents with columns and sidebars convert poorly. Choose a plain text document.
Trying it on a scan
A scanned PDF holds a picture of text, so nothing comes out. Check that you can select text before you start.
Your document stays on your device
The conversion happens locally. Your PDF is read by your own browser, rewritten there and handed back as an EPUB. Nothing is uploaded, so no copy ends up on a server and nobody else can read it. For books and papers with private content, that is the safe way to convert PDF to EPUB.
Summary
To convert PDF to EPUB here, drop the document and press the button. Your PDF is read in your browser and written out as EPUB. A PDF records where each letter sits, not what it means, so headings, paragraphs, lists and tables are worked out from position and size. They are kept, with bold, italic and pictures, as reflowable text, so it reads properly at any type size on any reader. The book arrives as a single chapter with one entry in its table of contents, and page layout, columns, headers and footnotes are dropped. A scanned PDF yields nothing. Nothing leaves your device.
