Convert RAW to JPG in your browser by extracting the JPEG preview the camera already stored inside the file. Canon CR2, Nikon NEF and DNG files each carry a preview rendered at the moment of capture, often at full resolution; this tool finds the largest and saves it as a .jpg, byte for byte, without re-encoding. It is a fast way to share, sort or check a card of RAW shots on a computer with no RAW software. It does not develop the sensor data, so exposure and white balance stay as the camera set them. Nothing is uploaded.
How it works
- Drop CR2, NEF or DNG files. They are told apart by their contents, so a renamed file is still read correctly.
- Nothing to set: RAW previews always come out as JPG, and the quality slider does not apply because nothing is re-encoded.
- Press Convert & download. Each result line gives the preview’s exact pixel size, and a batch arrives as one ZIP.
Questions
- Which RAW formats can I convert to JPG?
- Canon CR2, Nikon NEF and DNG, whichever camera or app wrote the DNG. Files are recognised by their contents, not the extension. Other RAW types, including Canon’s newer CR3, Sony ARW and Fujifilm RAF, are not supported here.
- Why can’t I save a RAW file as PNG?
- Because there is nothing to convert. The preview inside a RAW file is already a finished JPEG, and this tool copies it out exactly as the camera wrote it. Turning that into a PNG would make the file several times larger without adding any detail, so RAW files always save as .jpg, whatever the format setting says.
- Why was my RAW file refused?
- Either the format is not one this tool reads, or the largest preview inside is under 1 megapixel, which is a thumbnail rather than a usable photo; the message says which, with the preview’s dimensions. Nothing guessed is ever returned: a preview is only accepted when it is a valid JPEG with readable dimensions.
- 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.
