HOW TO CONVERT SR2 → AVIF
Provide the SR2
Click or drag to upload. We accept a single SR2 file per job, with an optional queue of additional images for batch mode.
Encode to AVIF
The conversion decodes the SR2, resolves the colour space to sRGB and writes the AVIF container around the pixel data.
Save the AVIF
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all AVIF outputs is produced instead.
Starting point: SR2 is a raster image format with its own balance of compression, colour depth, and software support. Natural next step, a AVIF. A SR2 → AVIF operation is one of the simplest image jobs there is: same pixel grid, different wrapper. What genuinely changes is how lossy the codec is, whether alpha survives, and how large the final file ends up. KaijuConverter picks safe defaults for each of those and lets you override them under Advanced. A quick refresher — SR2 is a raster image format with its own balance of compression, colour depth, and software support. By contrast, AVIF is the AV1-based next-gen image codec, extremely efficient with full HDR and alpha support.
Why convert SR2 to AVIF
The real reason to move from SR2 to AVIF is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking AVIF solves those edge cases at the cost of a short conversion step.

SR2 vs AVIF — Strengths and limitations
What each format does best, and where it falls short.
SR2 Strengths
- Full Sony Alpha early-era sensor data preserved.
- Supported by major raw processors.
- Metadata includes Konica Minolta pre-Sony era compatibility.
Limitations
- Transitional format — limited to 2006-2008 bodies.
- Superseded by ARW.
- Proprietary with no public spec.
AVIF Strengths
- Best-in-class compression efficiency — 30-50% smaller than JPEG for the same quality.
- Royalty-free and patent-unencumbered (unlike HEIC).
- Supports alpha transparency, HDR, wide gamut (BT.2020), and up to 12-bit color.
- Progressive decoding: a blurry preview appears while the file is still downloading.
- Supported in all major browsers since late 2022 — no polyfills needed.
Limitations
- Encoding is CPU-expensive — an AVIF export can take 10-30× longer than JPEG.
- Older software (pre-2022) cannot open AVIF without plugins.
- Email clients still largely ignore it — stick to JPEG for attachments.
Quality & Compatibility
SR2-to-AVIF conversion does not change the visible content. Quality is capped by the SR2 decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original SR2 alongside the AVIF copy.
Tips for Best Results
- Large SR2 files may look identical to small AVIF files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export AVIF at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related SR2 images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
It depends on the codecs involved. If both SR2 and AVIF are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If AVIF is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded SR2 exactly, but cannot recover detail that SR2 had already compressed away.
Often yes, especially when AVIF is lossless. SR2 tuned for efficient web delivery will usually produce smaller files than AVIF's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
Sony RAW SR2
Source formatSR2 is an older Sony RAW format used in some Sony Alpha cameras. Newer Sony cameras use ARW instead.
AVIF Image
Target formatAVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining excellent visual quality, including HDR and wide color gamut support.
Common Use Cases
Share across platforms
Send AVIF files to anyone without worrying about whether they have the right software for SR2.
Embed in documents
Drop AVIF output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
AVIF often produces smaller files than SR2 for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
