How is it possible without a RAW developer?

Canon CR2/CR3 files embed a full-resolution JPEG preview alongside the raw sensor data. This tool finds and extracts that preview — no de-mosaic step is needed.

Will it work for NEF, ARW, RAF, DNG?

Often yes — most modern RAW formats embed a JPEG preview. The extractor scans the file for the largest embedded JPEG so it works on many RAW formats even though it is tuned for CR2/CR3.

Are my photos uploaded?

No. Bytes are scanned in the browser via the File API. Nothing leaves your device.

How CR2 to JPG works

Pick one or more .cr2 or .cr3 files.
The browser scans each file for the largest embedded JPEG (the full-resolution preview).
Press Extract JPG preview and download the resulting JPEG.

Common use cases

Quick photo sharing: get a usable JPEG straight from a RAW shoot without booting Lightroom.
Triaging RAWs: generate previews you can scroll through on a phone or tablet.
Recovering lost JPEGs: when the dual-format setting failed, the in-RAW preview is still there.

Frequently asked questions

Is this the same quality as a developed RAW?

No — the embedded preview is what the camera produced at capture time. It's good enough to publish, but it doesn't reflect any edits you'd make in a RAW developer.

Why is the result smaller than the sensor resolution?

Some Canon bodies embed a slightly downsized preview to save space. Most recent bodies (5D Mk IV, R-series) embed a full-resolution JPEG.

It says "no JPEG found"?

Either the body wrote a non-standard preview or the file was renamed but is not actually a CR2/CR3. Confirm with the EXIF Viewer.
