Convert Canon CR3 to WebP — in your browser, no upload

Turn Canon CR3 RAW files into WebP — modern, smaller than JPG — all at once. Files never leave your device; everything is decoded right here in your browser. No sign-up, no watermark, no limits.

What is a CR3 file?

CR3 is Canon's current RAW format, introduced with the EOS M50 and now written by every EOS R-series mirrorless body and recent PowerShot. Unlike the older TIFF-based CR2, a CR3 is built on the ISO Base Media container (the same box structure as MP4) and can store more efficient compressed raw (C-RAW) alongside the full uncompressed capture. It holds the unprocessed sensor data, so standard photo viewers, browsers and upload forms usually can't open a CR3 without converting it first.

What is WebP, and why convert CR3 to it?

WebP is a modern image format developed by Google that delivers smaller files than JPG at comparable quality. It is supported by all current browsers and is widely used to speed up websites. For RAW conversion it is a good middle ground: noticeably smaller than JPG, while still a normal, shareable image.

Convert Canon CR3 to WebP when you want the smallest practical file for the web — product photos, galleries, blog images — without a visible quality drop. At the same perceived quality a WebP is typically 25–35% smaller than a JPG, which means faster page loads. Pixadel develops the CR3 fully and encodes WebP at the quality you choose (default 92). For maximum compatibility with older software, JPG is still the safer pick.

Why convert CR3 with Pixadel

Canon's Digital Photo Professional needs a desktop install and is built for deep colour work — far more than you need when the goal is just JPGs to send or post. Pixadel is install-free, runs entirely on your device, and turns a whole folder of CR3s into a ZIP of JPGs in one pass. No account, no queue limits, and nothing is uploaded — the raw stays on your machine the entire time.

How CR3 → WebP conversion works

Pixadel reads both standard CR3 and Canon's compressed C-RAW variant, demosaicing each frame with the camera's recorded white balance before encoding to JPG so colours and detail match the camera's own rendering. Quality is yours to set (default 92), with an optional half-size export for quick previews. Because CR3 files from 30–45 MP bodies are large, conversion runs in a worker pool that handles one file per worker at a time — keeping memory flat so big batches finish without crashing the tab.

Frequently asked questions

Is WebP supported everywhere?
All current browsers and most modern apps support WebP. Some older desktop software does not — if you need universal compatibility, convert CR3 to JPG instead.
How much smaller is WebP than JPG?
At equivalent visual quality, WebP files are usually 25–35% smaller than JPG, which is why it is popular for web performance. You still control the quality (default 92).
Can I convert many CR3 files at once?
Yes — drag a whole folder in. Pixadel queues every file and converts them with a worker pool, then hands you one ZIP. There’s no cap on file count.
Does the quality drop?
You control JPEG quality (default 92). The RAW is fully decoded — demosaiced with the camera-recorded white balance — before encoding, so results match what your camera would have produced.
Are my files uploaded anywhere?
No. Decoding happens in your browser via libraw compiled to WebAssembly. Nothing is sent to a server — refresh the page and the files are simply gone.
Does compressed C-RAW work, and what about CR2?
Both work. Pixadel reads Canon’s C-RAW compression as well as standard CR3, and the older CR2 from EOS DSLRs has its own CR2 → JPG page.
