Converting CR3 to AVIF
Drop a CR3 file and it is decoded in your browser, then re-encoded as AVIF with the quality and background you choose. Transparency is preserved when the target format supports it and flattened onto a colour when it does not. Camera orientation is applied so the result is never sideways, and EXIF data is dropped, which protects your location and shrinks the file. Batches of up to 50 files convert together and download as a ZIP, with no upload, no queue and no account.
Who needs this
People sharing iPhone or Android photos with systems that only accept AVIF, web developers moving to modern formats, designers exchanging assets, and anyone who needs CR3 files to open on another device.

Frequently asked questions
Does converting CR3 to AVIF reduce quality?
Converting into a lossless format keeps every pixel. Converting into a lossy one re-encodes at the quality you set; 92 percent is visually identical for photos and still far smaller than the original.
Why would I want AVIF instead of CR3?
Compatibility and size. AVIF opens where CR3 may not, and modern formats can be much smaller for the same look. The compare slider shows both side by side.
Is transparency kept?
Yes when AVIF supports it (PNG, WebP, AVIF, ICO). JPG and BMP do not, so transparent areas are filled with the background colour you pick.
Can I convert many CR3 files at once?
Yes. Add up to 50 files, run once, and download them as a ZIP. Each file is converted in a background worker so the page stays responsive.
Which formats are supported?
Input: JPG, PNG, WebP, AVIF, GIF, BMP, SVG, TIFF and HEIC/HEIF from iPhone. Output: JPG, PNG, WebP, AVIF, BMP and ICO.
How do I convert HEIC to JPG?
Drop the .heic files, keep JPG selected and press Convert. HEIC is decoded on your device with a WebAssembly decoder; nothing is uploaded.
What happens to transparency?
PNG, WebP and AVIF keep it. JPG and BMP have no alpha channel, so transparent areas are filled with the background colour you choose.
