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

Turn Canon CR3 RAW files into PNG — lossless, pixel-perfect — 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 PNG, and why convert CR3 to it?

PNG is a lossless image format: it stores every pixel exactly, with no compression artifacts. It is universally supported and is the format of choice when you need a perfect copy of the developed image — for editing, archiving, or placing graphics over a clean background — rather than the smallest possible file.

Convert Canon CR3 to PNG when you want a lossless render you can edit repeatedly without quality loss, or a clean master to hand to a designer. Unlike JPG, a PNG won't introduce blocking or ringing around edges, so fine detail and text stay crisp. The trade-off is size: PNG files are large (often several times bigger than a JPG of the same image). Pixadel decodes the CR3 fully and writes a true-colour PNG with no recompression.

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 → PNG 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

Why is the PNG so much larger than a JPG?
PNG is lossless — it keeps all pixel data instead of discarding detail to save space. Expect a PNG to be several times the size of a JPG of the same CR3. Use PNG when fidelity matters more than size; use JPG to share.
Does converting CR3 to PNG lose any quality?
No. The CR3 is fully developed and the result is stored losslessly, so the PNG is a pixel-exact copy of the rendered image — there is no quality setting because none is needed.
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.
