PostScript to EPUB Converter

Convert PostScript to EPUB: What This Tutorial Covers

This walks you through turning a PostScript (.ps) file into a reflowable EPUB ebook you can read on a Kobo, Apple Books, Google Play Books, Calibre, or — via Send to Kindle — a Kindle. It also covers the part most converters quietly skip: PostScript is a fixed-layout print stream and EPUB is reflowable, so the conversion extracts content and re-flows it rather than reproducing the page. Expect a readable ebook of the text, not a pixel-faithful copy. If your goal is to view or archive the file exactly as it looks, converting to PDF is the faithful path instead.

How to Convert PostScript to EPUB

1. Upload Your PostScript File: Drag and drop your .ps file onto the page or click "+ Add Files". You can queue several files and convert them with the same settings.
2. Pick a Compression Type: Open Advanced Options and choose a Compression Type preset — Screen (Best) keeps the most visual detail and is the default; Ebook, Printer, and Prepress trade file size against fidelity for any rasterized graphics pulled into the ebook. This setting affects embedded figures, not the extracted text.
3. Confirm EPUB as the Output: EPUB is already selected as the target. Leave it as is to build a reflowable EPUB 3 package; the defaults produce a valid ZIP-based container of XHTML and CSS.
4. Convert and Download: Click "Convert" and download the .epub. Open it in your reader or side-load it to a device. No sign-up, no watermark.

Walk-through: Why a Print Stream Becomes a Simplified Ebook

PostScript was never designed to reflow. It describes a finished page the way a printer driver sees it — "place this glyph at this x/y coordinate, draw this line here" — with no paragraph objects, no heading styles, and no chapter structure to recover. EPUB is the opposite by definition: the W3C EPUB 3.3 specification states that publications "by default are intended to reflow to fit the available screen space." Bridging the two means the converter has to pull text out of those positioned print commands and pour it into flowing XHTML that re-wraps to each reader's screen and font size.

What that means in practice, and how to get a cleaner result:

• The text comes through; the page geometry does not. Words and embedded images are extracted into the ebook, but the original column widths, line breaks, margins, and exact positioning are discarded — that is reflow working as intended, not a fault.
• Structure is approximate. Because PostScript has no real heading or chapter marks, the navigable table of contents an EPUB normally builds from headings may be thin or flat. The ebook is still readable cover to cover; it just may not have rich chapter navigation.
• For mostly-text documents this works well. A single-column PostScript report, letter, or plain academic paper reflows into a perfectly usable ebook. The more a page relies on print layout, the more it gets simplified.
• If you only need to read figures and equations in place, a fixed-layout target preserves them better — see the alternatives section below.

What Survives the Conversion and What Doesn't

Common Issues and How to Fix Them

• "My multi-column paper is scrambled" — PostScript stores text by position, not reading order, so a two-column journal page can interleave when flattened to one column. For multi-column or layout-heavy papers, convert to a fixed layout with PS to PDF instead.
• "Equations and figures look like images" — Math and figures in PostScript are frequently drawn as vector outlines with no underlying text, so they survive only as flattened graphics. That is unavoidable from a print stream; the PDF route keeps them sharp and in place.
• "Some text is missing or shows as boxes" — The source used a custom or Type 3 font that wasn't fully embedded, so glyphs can't be mapped to characters. Re-export the original with fonts embedded, or go through PS to PDF first.
• "The EPUB won't open on my Kindle" — Older Kindles don't read .epub straight off the filesystem. Use Amazon's Send to Kindle (web, app, or email), which accepts EPUB and converts it to the Kindle format on Amazon's side.
• "The ebook has no chapter navigation" — PostScript carries no heading marks for the converter to build a table of contents from, so navigation can be flat. This is a limitation of the source format, not the conversion.

When This Doesn't Work — and the Faithful Alternative

PS to EPUB is the right move when you want to read a legacy PostScript document — an old academic paper, a TeX/dvips output, a Unix-archive manuscript — on an e-reader with adjustable text. It is the wrong move when the layout is the point. Multi-column journal articles, documents dense with equations and figures, and anything with precise print positioning will be stripped down by reflow no matter how the source was designed.

For those, keep the exact page layout by converting PS to PDF — PostScript and PDF are close relatives, so that conversion is faithful in appearance and is what PostScript was effectively built to become; most readers also open PDF directly. If you specifically want an ebook but the direct route is messy, a reliable two-step is to make the PDF first and then run PDF to EPUB, which can do a cleaner job of text-flow reconstruction. And if you just need an editable text copy rather than an ebook, use PS to DOCX.

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.

Frequently Asked Questions

Will the EPUB look like the original PostScript page?

No, and that is by design. PostScript is a fixed-layout print format and EPUB is reflowable — text re-wraps to fit each reader's screen and font size, so the original columns, line breaks, margins, and exact positioning are not reproduced. You get the readable text and embedded images, not a page-faithful replica. If you need the file to look exactly as authored, convert PS to PDF instead.

Should I convert PS to PDF instead of EPUB?

If your goal is to view, archive, print, or share the document exactly as it looks — especially anything with multiple columns, equations, or figures — yes, use PS to PDF. PostScript and PDF are close relatives, so that conversion is faithful in appearance and most apps open PDF directly. Choose EPUB only when you specifically want reflowable text you can resize and read comfortably on an e-reader.

Why are my equations and figures coming through as images?

Math, formulas, and figures in PostScript are commonly drawn as vector outlines rather than live characters, so there is no text for the converter to reflow — they survive only as flattened graphics. This is a limitation of how the source PostScript was written, not the conversion. The PDF route preserves them sharply and in their original position.

Can I send the converted EPUB to a Kindle?

Yes. Amazon's Send to Kindle (web uploader, desktop and mobile apps, or your @kindle.com email address) accepts EPUB and converts it to the Kindle format automatically. Through email the file must be 50 MB or smaller; the Send to Kindle web and app uploads allow files up to 200 MB. Amazon no longer accepts the older MOBI format, so EPUB is the format to send.

Which EPUB version does this produce, and what readers open it?

It outputs an EPUB 3 package — a ZIP-based OCF container of XHTML and CSS, the structure defined by the W3C EPUB 3.3 Recommendation (published May 2023). EPUB 3 opens in Apple Books, Kobo, Google Play Books, Calibre, and most current e-readers; for Kindle, route it through Send to Kindle as described above.

How are my files handled, and how long are they kept?

Your .ps file is uploaded over an encrypted connection and processed on our servers — there is no in-browser-only mode for this conversion. Files are deleted automatically a few hours after conversion and are never shared or made public. No account or sign-up is required, and the output carries no watermark. In our testing, a single-column PostScript paper converts to a clean, navigable EPUB, while a dense multi-column journal page loses its layout to reflow — keep your original .ps as the master copy and convert from it whenever you need a different format.
