EPUB to PDF Converter

EPUB is made for reading apps and e-readers, while PDF is the format almost everyone can open and print without installing anything. Convert when the book has to be printed, sent to someone with no reading app, or attached to a submission that only accepts PDF. If the result is for one particular screen, the reader setting can be pointed at Apple iPad or Kindle Paperwhite instead of Default.

An EPUB is a package of text, pictures and chapter structure that a reading app arranges to fit whatever screen it is on, so it has no fixed pages. A PDF is the opposite: a set of finished pages with everything locked in position. The conversion therefore has to build pages that never existed, which is why a margin in centimetres, anywhere from 0 to 10, is asked for before you start.

Choose your model if it is listed, since the layout is then tuned to that screen's size and behaviour. Default is perfectly fine otherwise, and is the right answer for reading apps on a phone or tablet, or for a device that is not in the list.

• Your exact model - the best fit when you have that device in hand
• Default - reading apps, tablets, computers, or an unlisted or newer device

Leave it unchanged unless the text is genuinely uncomfortable to read, since the original sizes were chosen to work together. If you do need a change, pick the size you would like ordinary body text to be, and everything else follows in proportion.

• No Change - the usual choice, especially for a device where you can already adjust text size while reading
• Around 11 to 13 - a comfortable everyday reading size
• 16 and above - large-print reading, or a document to be read at arm's length or on a screen across the room

Leave them small if the file will be read on a phone or e-reader, since screen space is precious and the device usually adds its own spacing. Go wider when the file is destined for paper or for reading on a large screen, where a generous margin makes long passages easier on the eye.

• 0 to 1 cm - reading on a phone or small e-reader
• 2 to 3 cm - printing, or comfortable reading on a tablet or computer
• 4 cm and above - documents you want to annotate by hand or bind

Fill it in when the existing title is wrong, blank or unhelpful - a filename, a website address or a string of numbers - because that is what you will see in your library. If the file already shows the correct title in your reading app, leave the field empty and it will be kept as it is.

• Enter one - documents converted from a web page or a word processor file, where the title is often just the filename
• Leave it empty - published books that already display correctly

Try it when your source is messy and the converted result looks wrong - stray line breaks mid-sentence, odd spacing, or chapters that run into one another. Leave it off for files that already look tidy, since a well-formatted document has nothing to fix and the feature is experimental. It is quick to convert twice and compare.

• Yes - documents scraped from web pages, converted from old files, or full of odd breaks and spacing
• No - professionally produced files that already read cleanly

Leave it on Auto unless something has gone wrong, since detection is right the great majority of the time. Set it by hand only when the converted text is full of strange symbols, question marks or boxes where accented or non-Latin letters should be - a sign the file declared the wrong encoding, or none at all.

• Auto - the default, correct for almost every file
• UTF8 - the modern standard, and the first thing to try when text comes out garbled
• A specific regional option - older files in Korean, Japanese, Hebrew or Cyrillic that predate the modern standard

Your choice overrides whatever the file itself declares, so an incorrect one will make good text come out garbled - which is the main risk of changing this at all. Nothing is damaged permanently, since the original file is untouched, so you can simply convert again with a different choice. Plain English text usually survives regardless, because most codebooks agree on the basic Latin letters; it is accents and other alphabets that reveal the mismatch.

Only turn this on if your reading device is actually struggling. Modern apps and e-readers display accents, Cyrillic, Greek and similar text perfectly well, so the setting is normally left off and your text keeps its original spelling. It exists for older hardware, where unsupported characters can show up as empty boxes or question marks and make sentences hard to read.

• Leave it off - for reading on a phone, tablet, a current e-reader or a computer
• Turn it on - for an old or very basic reading device that shows boxes instead of letters
