SR2 to CBZ Converter
FileFlip converts SR2 to CBZ entirely inside your browser, using ImageMagick and MuPDF 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 CBZ?#
- 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 CBZ and the conversion starts on its own. FileFlip downloads 24.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick and MuPDF on your own machine.
- Save the CBZ file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting SR2 to CBZ lose quality?#
No. The SR2 picture is placed into the CBZ document at its full resolution, so every pixel reaches it intact. What you give up is that it becomes a picture inside a document rather than text.
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 CBZ actually does to the file#
Converting SR2 to CBZ runs on ImageMagick and MuPDF, downloads 24.1 MB of WebAssembly the first time and nothing after that, places the picture into the document at full resolution.
| Engine | ImageMagick and MuPDF |
|---|---|
| Conversion path | 2 steps: SR2 → PNG → CBZ |
| Downloaded to your browser | 24.1 MB, once, then cached by your browser |
| Quality | Pixels preserved |
| 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
- the picture is placed in the document as a picture; no text is recognised out of it
- 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 CBZ file?#
A CBZ file is a ZIP archive of page images, usually JPEG or PNG, named so they sort into reading order, with nothing else defining it as a comic beyond that convention.
Use CBZ to distribute a scanned or digital comic as sequential page images that any comic reader opens without conversion.
Convert CBZ to PDF when a comic needs to move into software that expects a page-based document instead of a folder of images.
SR2 to CBZ 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 CBZ file?
A CBZ file is a ZIP archive holding a comic's pages as individual image files, named so they sort into the right reading order. There is no page-layout data or text encoding involved, which is the entire format: a comic reader just opens the ZIP and displays the images in sequence.
