No. Everything runs in this browser tab on your own device. Engines are downloaded once and cached, but your files never leave your computer.

Which cameras are supported?

Anything LibRaw supports, which covers almost every camera made in the last 20 years. A few very new compressed formats may fail; in that case the embedded preview is still shown.

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.

RAW Photo Converter

Develop camera RAW files (CR2, CR3, NEF, ARW, DNG, RAF, ORF and more) to JPG, PNG or TIFF with exposure and white balance.

Free, no uploads, no sign-up. Runs 100% in your browser.

How RAW Photo Converter works

RAW files are decoded with LibRaw compiled to WebAssembly, running in a Web Worker so the page stays responsive. You can adjust exposure, brightness, white balance and highlight recovery, preview the result, and save a full-resolution JPG (MozJPEG), PNG or TIFF.

Input: CR2, CR3, CRW, NEF, NRW, ARW, SR2, DNG, RAF, ORF, RW2, PEF, SRW, 3FR, ERF, MOS, MRW, X3F, IIQ, GPR, KDC. Output: JPG, PNG, TIFF, WEBP.

How to use RAW Photo Converter

Drop a RAW file from your camera.
Check the embedded preview and camera details.
Adjust exposure, white balance and highlights, then press Update preview.
Pick a format and press Convert.

Tips

Turn on Half size for a much faster export when you only need a web-sized photo.
"As shot" white balance uses what the camera recorded and is usually the best start.
