SCR to GIF87 Converter
FileFlip converts SCR to GIF87 entirely inside your browser, using ImageMagick 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 GIF87?#
- 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 GIF87 and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the GIF87 file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting SCR to GIF87 lose quality?#
No. Converting SCR to GIF87 writes the data out again without discarding any of it, so nothing that was in the SCR file is lost on the way. What changes is the size of the file, not what is inside it.
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 GIF87 actually does to the file#
Converting SCR to GIF87 runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, writes the data out again without discarding any of it.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: SCR → GIF87 |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossless |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
Worth knowing before you start:
- the target holds at most 256 colours, so a full-colour image is quantised to a palette
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 a GIF87 file?#
A GIF87 file follows the original 1987 Graphics Interchange Format specification that CompuServe published two years before GIF89a added transparency and animation, so it stores a single, fully opaque image using the same LZW compression and 256-color palette as any other GIF.
There's essentially no reason to target GIF87 today; write a plain GIF, which is GIF89a, instead unless a specific tool or test needs the older header.
Convert to GIF89a or PNG when the image needs transparency or animation, since GIF87 supports neither.
SCR to GIF87 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 a GIF87 file?
A GIF87 file follows the original 1987 Graphics Interchange Format specification that CompuServe published before adding transparency and animation in 1989's GIF89a. It stores a single, fully opaque static image.
