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.

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.
