RAW to JPG Converter

RAW to JPG turns sensor data into a picture. A CR2, CR3, NEF, ARW, or DNG file isn't an image yet - it's the camera sensor's raw readings, waiting to be demosaiced, white-balanced, and tone-mapped. Until that development step happens, the file won't preview properly on most systems and can't be shared at all. This tool runs that step and hands back a universally viewable JPG.

The development runs on your device: LibRaw, the open-source RAW decoder behind a number of desktop photo apps, is compiled to WebAssembly and runs in a background worker in your browser. It demosaics the sensor data, applies the camera's recorded white balance, and passes the pixels to the Canvas API for the JPG encode. Nothing is uploaded, and a 24-megapixel file develops in a couple of seconds on a typical desktop. The rendering is neutral, comparable to the camera's own default output - right for proofing, culling, and sharing, while creative develops stay the job of Lightroom-class editors.

Prefer the camera's own look? The Camera preview option pulls the JPEG the camera embedded in the RAW, picture style and all, in a fraction of a second; many Canon, Nikon, and Pentax DSLRs store it at full resolution. Either way, the size difference is the format working as intended: a 25-60 MB RAW carries 12-14 bits per channel of editing headroom, while the JPG distills the final image into a few megabytes. Keep the RAW as your negative; the JPG is the print.
