Quick Answer: How to Convert CR2 to DNG
CR2 is Canon Raw 2 — unprocessed sensor data straight from Canon DSLRs. Converting it to DNG runs the full raw-development pipeline — demosaicing, white balance, color profile — and bakes those settings into the output, the same way your camera's JPEG engine would. Run it free at practicalwebtools.com/convert/image/cr2-to-dng: drop in your CR2, adjust settings if you like, and download the DNG — no signup, no upload, everything stays on your device.

- 1
Add your CR2 file
Drag and drop it into the converter, or click to browse. CR2 files up to the size limit are accepted, and nothing is uploaded — processing runs locally in your browser.
- 2
Set DNG options
Pick your quality: the converter exposes the settings that matter for DNG. Higher bitrates preserve more of the CR2's detail at larger file sizes.
- 3
Download the DNG
Conversion runs on your device. When it completes, download the DNG file — repeat for as many files as you need, free and unlimited.
Key Facts About CR2 to DNG Conversion
- CR2: Canon, 2004 (EOS 20D era) through 2018, lossless or lightly-compressed raw sensor Bayer data.
- DNG: Adobe, 2004, lossless raw with options; can embed the original file.
- CR2 strength: every photon the sensor captured, with 12/14-bit depth.
- DNG strength: open specification — no proprietary format decay.
- CR2 limitation to know: needs demosaicing to become viewable.
- DNG limitation to know: camera makers mostly refuse it natively (Apple, Pentax, Leica, some DJI are exceptions).

Frequently Asked Questions
Will converting CR2 to DNG lose quality?
It depends on the formats: CR2 is lossless or lightly-compressed raw sensor Bayer data and DNG is lossless raw with options; can embed the original file. Any step from a lossless source into DNG keeps everything; any lossy step re-encodes and discards some data.
Are my files uploaded anywhere during CR2 → DNG conversion?
No. This converter runs on WebAssembly inside your browser — your CR2 file is read from disk, processed by your device's CPU, and the DNG is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.
Why does my DNG look different from the camera preview?
CR2 is Canon Raw 2 — unprocessed sensor data straight from Canon DSLRs. A raw file isn't an image yet — the converter applies a development pipeline (demosaicing, white balance, tone curve) to produce the DNG, and different settings yield different-looking results from the same raw file, exactly like a darkroom.
Is DNG still a current format in 2026?
Lightroom-native, wide tool support, some cameras write it directly. DNG can embed the complete original RAW file inside itself — convert CR2→DNG with "embed original" and you lose nothing, ever
Do I need to install anything to convert CR2 to DNG?
No installation. The converter is a web page — open it in any modern browser on Windows, macOS, Linux, iOS, or Android. CR2 decoding and DNG encoding both run via WebAssembly at native-adjacent speed.
