Supported RAW formats
⚠️ CR3 (Canon), RAF (Fujifilm), RW2 (Panasonic), X3F (Sigma) use proprietary compression not decodable in the browser. Rename a DNG version for full support.
Image Format Converter — PNG, JPEG, WebP

Which format should I use?
PNG
Best for screenshots, logos, graphics with text, and anything needing lossless quality or transparency.
JPEG
Best for photographs. Set quality to 80–85% for a good balance of size and visual quality.
WebP
Best for web use. Smaller than both PNG and JPEG at similar quality. Use for all web images where possible.
