The formats ordinary tools reject: iPhone HEIC, multi-page TIFF, AVIF, mislabelled JFIF, and camera RAW (CR2, NEF, DNG) via their embedded full-size previews. Everything decodes on your device and saves as JPG or PNG; drop a folder and it comes back as a ZIP.
How it works
- Drop the files: HEIC, TIFF, AVIF, JFIF or RAW.
- Pick JPG (smaller) or PNG (lossless), and a quality for JPG.
- Download each result, or the whole set as a ZIP.
Questions
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- How are RAW files converted?
- Honestly: RAW files carry a full-size JPEG preview rendered by the camera, and that is what this tool extracts, instantly and losslessly. It does not demosaic the sensor data; a RAW developer with your own processing choices is the right tool for that.
- Why does HEIC need a special decoder?
- Browsers do not decode HEIC, so this page ships an open-source decoder (libheif, compiled to WebAssembly) that runs on your device. The photo itself still never leaves your machine.
