SR2 to JXL Converter
FileFlip converts SR2 to JXL 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 JXL?#
- 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 JXL 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 JXL file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting SR2 to JXL lose quality?#
It depends on what is inside the file. SR2 is a container rather than a codec, so whether the JXL conversion copies the streams across untouched or re-encodes them is decided by the codecs that particular file happens to use.
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 JXL actually does to the file#
Converting SR2 to JXL runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, re-encodes or copies through depending on the codecs in the file.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: SR2 → JXL |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Decided by the codecs inside the file |
| 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 a JXL file?#
A JXL file stores an image under the JPEG XL coding system, a format built to losslessly repackage an existing JPEG into a smaller file or to encode a new photo at higher quality per byte than JPEG, WebP or AVIF.
Use JPEG XL for archiving and photo libraries where you want smaller files than JPEG without giving up the option to reconstruct the original JPEG exactly, especially once Chrome and Firefox finish rolling out default decoding.
Convert JXL to JPEG or PNG for anything going on the web today, since most browsers still require a manual flag to display JPEG XL directly.
SR2 to JXL 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 a JXL file?
A JXL file is an image encoded with JPEG XL, a format from the JPEG standards committee designed either to losslessly shrink an existing JPEG or to encode new photos at better quality per byte than JPEG, WebP or AVIF. It became an ISO standard starting in 2021.
