Why Use Our RAW to PNG Converter
WASM-Powered RAW Decoding
Uses wasm-vips, a WebAssembly port of the Vips library with libraw, to decode RAW files accurately in your browser. Supports Canon CR2/CR3, Nikon NEF, Sony ARW, Adobe DNG, and more. No server uploads needed.
Lossless PNG Output
PNG preserves every pixel from the decoded RAW without recompression artifacts. Perfect for archiving or further editing of your RAW photos.
Batch Processing
Select multiple RAW files at once for batch conversion. Each image is processed independently with consistent quality settings, and you can download them all at once with one click.
Privacy & Local Processing
All conversion happens locally in your browser using WebAssembly. RAW files are never uploaded to any server. Your photos remain on your device at all times.
How to Convert RAW to PNG Online Free
Upload Your RAW Files
Click the upload area or drag RAW files into the browser. The tool accepts .cr2, .cr3, .nef, .arw, .dng, and many other RAW formats. Select multiple files at once for batch conversion. When you drop your files, you will see thumbnails showing a preview of each RAW image with its file name and dimensions. All processing stays in your browser — your photos never leave your device.
Convert to PNG
Click the "Convert to PNG" button to start. The tool loads the WebAssembly-based vips library with libraw support (usually takes a moment on first use) and decodes each RAW file into full-resolution pixel data, then encodes to PNG. Progress indicators show when each file has finished converting.
Download Your PNGs
Each converted PNG displays a preview with its file size. Download images individually with the per-file button, or click "Download All PNG" to trigger staggered downloads for every converted file — browsers handle them one by one automatically. If you want to convert more, click "Convert More Files" to start a new batch. The whole workflow is fast, local, and private.
RAW to PNG Tips
Why Convert RAW to PNG?
RAW files contain unprocessed sensor data with maximum editing flexibility, but they are large and not widely supported by web platforms or mobile devices. Converting to PNG creates universally compatible images with lossless compression. Unlike JPEG, PNG preserves every pixel exactly, making it ideal for further editing or archival purposes.
Supported RAW Formats
We officially support Canon CR2 and CR3, Nikon NEF, Sony ARW, and Adobe DNG. Many other camera RAW formats (Fujifilm RAF, Panasonic RW2, Olympus ORF, Pentax PEF, etc.) are supported experimentally through libraw but may not be fully tested. If your format isn't listed, try uploading — it may still work. For best results, use DNG if your camera supports it.
PNG vs JPEG
PNG is lossless and preserves every pixel from the decoded RAW, while JPEG uses lossy compression to reduce file size. Choose PNG when quality matters most and you need pixel-perfect results for further editing. Choose JPEG when file size is a priority and you can accept minor compression artifacts. Both formats are available in our toolkit.
Frequently Asked Questions
What RAW formats are supported?
We support Canon CR2/CR3, Nikon NEF, Sony ARW, and Adobe DNG files. Many other RAW formats (RAF, RW2, ORF, PEF, etc.) are supported experimentally via libraw but not officially tested.
Is PNG lossless?
Yes, PNG is a completely lossless format. When converting from RAW to PNG, every pixel from the decoded image is preserved exactly. Unlike JPEG, there is no compression artifacts or quality loss. Note that the RAW file itself may have been compressed by your camera, but the conversion to PNG is mathematically lossless.
