SCR Converter
FileFlip converts SCR files into 62 other formats entirely inside your browser, using ImageMagick, MuPDF and Pandoc compiled to WebAssembly. The SCR file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert an SCR file?#
- Drop your SCR file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
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 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.
The SCR file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
SCR 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.
