SCR to EPUB Converter
FileFlip converts SCR to EPUB entirely inside your browser, using ImageMagick, MuPDF and Pandoc compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an SCR file to EPUB?#
- Drop your SCR file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to EPUB and the conversion starts on its own. FileFlip downloads 79.9 MB of WebAssembly the first time and nothing after that, then runs ImageMagick, MuPDF and Pandoc on your own machine.
- Save the EPUB file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting SCR to EPUB lose quality?#
No. The SCR picture is placed into the EPUB document at its full resolution, so every pixel reaches it intact. What you give up is that it becomes a picture inside a document rather than text.
Is it safe to convert SCR files online?#
Yes, because nothing is uploaded. FileFlip converts SCR files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What SCR to EPUB actually does to the file#
Converting SCR to EPUB runs on ImageMagick, MuPDF and Pandoc, downloads 79.9 MB of WebAssembly the first time and nothing after that, places the picture into the document at full resolution.
| Engine | ImageMagick, MuPDF and Pandoc |
|---|---|
| Conversion path | 3 steps: SCR → PNG → HTML → EPUB |
| Downloaded to your browser | 79.9 MB, once, then cached by your browser |
| Quality | Pixels preserved |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
Worth knowing before you start:
- the picture is placed in the document as a picture; no text is recognised out of it
- the file passes through HTML on the way, so anything HTML cannot express does not survive
What is an SCR file?#
An SCR file is a byte-for-byte dump of a ZX Spectrum's display memory, always exactly 6,912 bytes, holding a fixed 256x192 pixel screen the way the Spectrum's own video hardware laid it out.
Use SCR when working directly with ZX Spectrum software or emulators, since it's the format those tools load and save natively without any conversion.
Convert SCR to PNG to view or share a ZX Spectrum screen anywhere outside an emulator or Spectrum-specific tool.
What is an EPUB file?#
An EPUB file is a ZIP archive of XHTML, CSS and image files plus a manifest, packaging a book as reflowable web content that an e-reader lays out to fit its own screen.
Use EPUB for any ebook meant to reflow to the reader's screen and open on Kobo, Apple Books, Google Play Books or Adobe Digital Editions.
Convert away from EPUB when a Kindle needs the file in KFX or AZW3, or when the fixed page layout of a PDF matters more than reflow.
SCR to EPUB questions people ask#
What is an SCR file?
An SCR file is a raw snapshot of a ZX Spectrum's screen memory, the exact bytes the Spectrum's hardware used to draw the display. It's always 6,912 bytes: 6,144 bytes of pixel data followed by 768 bytes of colour attribute data.
What programs open SCR files?
ZX Spectrum emulators load SCR files directly into screen memory, and general image viewers like XnView MP can open and convert them. Spectrum-specific paint tools such as ZX-Paintbrush also read and write the format natively.
Why are SCR files always exactly 6,912 bytes?
An SCR file is a direct dump of the ZX Spectrum's fixed-size display memory, which is always 6,912 bytes on real hardware, so the file size never changes regardless of what the screen shows.
What is an EPUB file?
An EPUB file is an ebook packaged as a ZIP archive of XHTML pages, CSS and images, which is why the text reflows to fit whatever device opens it rather than staying pinned to a fixed page. It is the open ebook standard, maintained by the W3C, and every major reading app supports it except Kindle.
