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

Turn Canon CR3 RAW files into TIFF — lossless archival master — 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 TIFF, and why convert CR3 to it?

TIFF is a lossless, high-fidelity image container long used in photography, printing and archiving. It stores the full developed image without compression artifacts and is the format many editing and print workflows expect as a master file. TIFFs are large, but they preserve every detail of the conversion.

Convert Canon CR3 to TIFF when you need an archival-quality master — for print, for handing into a professional editing pipeline (Photoshop, Affinity, print RIPs), or for long-term storage of the developed image outside the proprietary RAW. Pixadel decodes the CR3 fully and writes an uncompressed TIFF, so nothing is thrown away. Expect the largest file of any output here; for sharing or the web, choose JPG instead.

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 → TIFF 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 convert CR3 to TIFF instead of keeping the RAW?
The CR3 is a proprietary RAW that many editors and print shops can't open directly. A TIFF is a developed, standardized, lossless master that any professional tool accepts — useful when you need to hand the image off while keeping full quality.
Is the TIFF compressed?
Pixadel writes an uncompressed TIFF for maximum compatibility and fidelity, so files are large. If you need a smaller lossless file, PNG is usually more compact; for sharing, use JPG.
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.
