How a browser converts RAW without a 30 MB decoder
A RAW file is not just sensor data — cameras embed a fully rendered JPEG (it's what the rear LCD shows). Formats from Canon, Nikon and Sony are TIFF containers; this tool walks the IFD tree, collects every embedded image, skips the lossless-JPEG sensor data browsers can't decode, and extracts the largest real JPEG. That file is served to you unmodified — same bytes the camera wrote, including the camera's color rendering, sharpening and white balance.
The honest trade-off: this is the camera's rendering, not a raw development. Exposure recovery, highlight rescue and white-balance changes need a real raw developer (Lightroom, darktable, RawTherapee). For "I need to see / send / cull these shots as JPGs" — the actual reason most people search this — the embedded JPEG is exactly the right answer, and faster than any demosaicing pipeline could ever be.
| Format | Embedded JPEG | Notes |
|---|---|---|
| Canon CR2 (5D III) | 5760×3840 — full resolution | IFD0 strip |
| Nikon NEF (D750) | 6016×4016 — full resolution | SubIFD |
| Sony ARW (α7 II) | 1616×1080 preview only | Sony stores no full-size JPEG |
| Orientation | Preserved from the RAW | Portrait shots stay upright |
| Metadata | Output is the clean camera JPEG | RAW keeps the originals |
When NOT to use this
- You plan to edit exposure or color — develop the RAW properly in a raw editor; that is what the format is for.
- Sony ARW full-resolution needs — Sony embeds only a 1616×1080 preview (a format limitation, reported honestly in the size readout). Canon and Nikon embed full resolution.
- Scientific/forensic work — the embedded JPEG carries the camera's processing; use the raw data.
