ARW to GIF Converter
Convert ARW to GIF in your browser. The full-size JPEG Sony stores in the file is what gets converted, so the sensor coding never reaches the output. No raw development happens here. You get a GIF with an optimised palette of up to 256 colours per frame, dithered. Nothing is uploaded.

Why use Aback Images for arw to gif
Where the GIF goes next
GIF opens in every browser, operating system, chat app and editor.
GIF next to ARW
The GIF holds the camera preview's pixels with lossless compression: usually smaller than a 25 to 80 MB raw file, though far larger than a JPEG of the same photo.
No new artefacts
The preview inside the ARW is a camera JPEG; the GIF stores its decoded pixels losslessly, so this step adds no compression damage of its own.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
ARW vs GIF
What changes from ARW to GIF
Encoding: the ARW uses Sony's lossy compressed raw, uncompressed (since the A7R II) or lossless compressed (since the A1); GIF uses lossless LZW over a palette of at most 256 colours, and the download is a GIF with an optimised palette of up to 256 colours per frame, dithered.
Bit depth: 12 or 14 bits per channel in the ARW; GIF allows 8 bits per pixel, as indexes into a palette, and the GIF written here has 8 bits per pixel (palette). The sensor's 12 or 14 bits are not used: the 8-bit camera preview is converted.
Colour: camera RGB from a Bayer mosaic in the ARW; GIF supports an indexed palette of up to 256 colours per frame, written here as an indexed palette of up to 256 colours.
Metadata: the ARW can carry EXIF, Sony maker notes, a thumbnail and a full-size JPEG; GIF can carry comment and application extension blocks, but no EXIF, but nothing is copied across.
About ARW
ARW is the raw format of Sony Alpha, RX and Cyber-shot cameras. It stores the sensor data (compressed, uncompressed or lossless compressed, depending on the model) with a full-size JPEG preview.
ARW is TIFF-based: the first directory carries EXIF and Sony's JPEG preview and the sensor data sits in a sub-directory. In Sony's classic compressed raw each block of 16 same-colour pixels keeps an 11-bit maximum and minimum plus 7-bit steps for the rest, which can leave artefacts beside high-contrast edges.
ARW files usually come from Sony Alpha mirrorless and SLT cameras, RX compacts and some Cyber-shot models.
About GIF
GIF is the classic animated image format. It is limited to 256 colours per frame and 1-bit transparency, so photos look grainy and files are large, but it plays everywhere.
A GIF starts with 'GIF89a' (or the older 87a), a logical screen descriptor and an optional global colour table, then image blocks, each preceded by a graphic control extension that sets its delay and transparent colour.
When converting ARW to GIF makes sense
GIF is the better choice for short animations and reactions that must play everywhere, while ARW suits editing Sony photos in a raw developer.
GIF strengths: Animation that works everywhere; Simple, universally supported; Good for small flat graphics. Drawbacks to weigh: Only 256 colours per frame; Hard-edged transparency only; Large files for photos or long clips.
Limitations
- Creative Look or Picture Profile settings are baked into that preview; a raw editor can start again from neutral.
- GIF holds at most 256 colours per frame, so ARW colour is reduced and gradients are dithered.
- GIF stores at most 256 colours per frame, so photographs show dithering or banding.
- GIF transparency is all or nothing per pixel, so soft shadows and anti-aliased edges get a hard fringe.

Frequently asked questions
Does converting ARW to GIF lose quality?
GIF is written losslessly, so the pixels are stored exactly as decoded. Those pixels come from the camera's JPEG preview, so its compression stays, but nothing new is lost. The sensor's 12 or 14 bits are not used: the 8-bit camera preview is converted.
Which apps open GIF files?
Every browser, operating system, chat app and editor.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
