SR2 to AVIF Converter
FileFlip converts SR2 to AVIF 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 SR2 file to AVIF?#
- Drop your SR2 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 AVIF 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 AVIF file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting SR2 to AVIF lose quality?#
Yes, once. SR2 keeps everything and AVIF does not, so this is the first time the file meets a lossy encoder. At high quality the difference is hard to see, and it is worth keeping the SR2 original, because every later re-save of the AVIF loses a little more.
Is it safe to convert SR2 files online?#
Yes, because nothing is uploaded. FileFlip converts SR2 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 SR2 to AVIF actually does to the file#
Converting SR2 to AVIF runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, encodes a lossless source with a lossy encoder for the first time.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: SR2 → AVIF |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossy, first generation |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
Worth knowing before you start:
- camera raw is demosaiced with ImageMagick's defaults, which will not match the camera's own rendering
- some cameras write lossily compressed raw, so the source is not always a complete sensor record
What is an SR2 file?#
An SR2 file holds raw sensor data from Sony's 2005 Cyber-shot DSC-R1, using less encryption than Sony had applied to its earlier SRF format, before Sony replaced it with ARW the following year.
SR2 only turns up from a small set of Sony cameras from 2005, most notably the Cyber-shot DSC-R1; there's no active reason to choose it.
Convert SR2 files to DNG or JPEG, since current raw processors and Sony's own software support ARW and DNG far better than this short-lived intermediate format.
What is an AVIF file?#
An AVIF file holds a still image or short animation encoded with the AV1 video codec, packaged inside a HEIF-style container that also carries HDR and wide-colour-gamut data alongside the pixels.
Use AVIF for web images where file size matters most, since it now decodes natively in every major browser and beats JPEG and WebP on compression at the same quality.
Convert AVIF to JPEG or PNG when a file is headed somewhere that still rejects it, such as an older content management system, a print workflow, or an app without AV1 decoding.
SR2 to AVIF questions people ask#
What's the difference between SR2 and SRF?
SR2 is the raw format Sony introduced after SRF, on cameras like the Cyber-shot DSC-R1, and it carries far less of the file-level encryption that made SRF hard for third-party software to decode correctly.
What's the difference between SR2 and ARW?
SR2 was the raw format Sony used briefly around 2005, on cameras like the Cyber-shot DSC-R1, before replacing it with ARW starting with the Alpha DSLR-A100 in 2006. Every Alpha DSLR, SLT and mirrorless camera Sony has released since has written ARW instead.
What Sony cameras produced SR2 files?
SR2 appeared on the Sony Cyber-shot DSC-R1, a bridge camera released in 2005. Sony replaced it with ARW the following year when it launched the Alpha DSLR-A100, its first Alpha-branded DSLR, and every Sony camera since has written ARW instead.
What is an AVIF file?
An AVIF file is an image compressed with the AV1 video codec instead of the older JPEG or WebP algorithms, which is why it produces noticeably smaller files at the same visual quality. It was created by the Alliance for Open Media, the same group behind the AV1 video format, and first shipped in 2019.
