Why Use Our RAW to AVIF 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.
Next-Gen AVIF Format
AVIF offers 50% better compression than JPEG at the same quality. Your RAW photos become ultra-efficient web files with support for HDR, wide color gamut, and alpha transparency. The future of web images.
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 AVIF 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.
Adjust Quality and Convert
Use the quality slider to set AVIF compression (10-100, default 85). Higher values mean better quality but larger files. Click the "Convert to AVIF" 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 AVIF. Progress indicators show when each file has finished converting.
Download Your AVIFs
Each converted AVIF displays a preview with its file size. Download images individually with the per-file button, or click "Download All AVIF" 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 AVIF Tips
Why Convert RAW to AVIF?
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 AVIF creates ultra-efficient modern images that work everywhere — email attachments, social media uploads, web hosting, and document embedding. AVIF is also much smaller than RAW and JPEG, making it practical for sharing and storage.
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.
Quality Settings Explained
The AVIF quality slider controls compression: 10 is smallest file size with visible artifacts, 100 is largest with minimal compression. 85 is the recommended default — excellent quality for most purposes. Use 90-100 for archival or print, 70-85 for web sharing, and lower values only when file size matters more than quality. Remember that RAW originals are always superior for editing — convert to AVIF as the final step for distribution.
