CR3 Editor Online
Edit Canon CR3 files online
Kalar provides an immediate, privacy-first way to open, color grade, and export Canon CR3 photos entirely in your web browser.

What is a CR3 file?
CR3 is the RAW image format used by modern Canon cameras. It contains uncompressed or losslessly compressed sensor data, requiring specialized decoding before you can view or edit it.
Can you edit CR3 in the browser?
Yes. Kalar decodes CR3 files locally in your browser using WebAssembly. There's no need to install heavy desktop applications just to open a few RAW files.
Why local processing matters
Your CR3 files are never uploaded. This means faster editing and guaranteed privacy for your original photos.
How Kalar approaches RAW editing
We provide a Lightroom-style workflow with precise exposure controls, color grading curves, and cinematic effects like halation and grain.
