Most online editors do one of two things with a RAW file: refuse it, or upload it to a server and hand you back a JPEG. Loupe does neither. The decoding happens inside your browser tab, so a 40-megapixel file is developed on your own machine and the original never goes anywhere.

It opens looking like your camera’s JPEG

Undeveloped RAW data looks dark and flat, which is why a lot of RAW converters open files looking worse than the photo on the back of the camera. Every RAW file carries a small JPEG preview made by the camera itself. Loupe reads it and matches its brightness and contrast, so if you shot a stop under on purpose, or your camera has a punchy picture style, the file opens that way.

What it does not copy is the camera maker’s colour recipe: film simulations, picture styles, creative looks. You get the brightness and contrast your camera chose, with neutral colour underneath.

The extra detail is still there

The point of shooting RAW is the headroom. Highlights that look white in the camera JPEG are often still recoverable in the RAW, and Loupe keeps them: bright areas are rolled off rather than cut off, so pulling the highlights down brings back cloud and sky instead of turning white into grey. Exposure works on the linear sensor data, the way it does in a dedicated RAW developer.

How long it takes

Opening takes about a second. Export happens at full resolution and takes a few seconds, because the whole file is developed again at full size. From our own test files, on the computer we build Loupe on:

  • Canon EOS R6, 20 megapixels: opens in 1.0s, exports in 4.5s
  • Nikon Z fc, 21 megapixels: 1.3s and 2.8s
  • Sony ZV-E10 II, 26 megapixels: 0.9s and 2.9s
  • Fujifilm X-T50, 40 megapixels: 1.1s and 9.1s
  • iPhone 12 Pro ProRAW: 1.5s and 1.1s

The AI part, briefly

You can edit with the sliders like any RAW developer. You can also ask: “recover the sky”, “warmer, like late afternoon”, “why does this look flat?”. The assistant moves the same controls you can see and says why. It never redraws the photo, so nothing in the frame is invented. When you ask, it sees a small preview of the picture, at most 512 pixels across. The RAW file itself stays on your computer. Ten AI edits a month are free, and the manual controls are free without limit. Pricing.
