Convert between every common image format — JPG, PNG, WebP, AVIF, GIF, HEIC, TIFF and more. Pick a lossless format like PNG for graphics and transparency, or a compressed one like JPG, WebP or AVIF for small, fast-loading web photos.

Frequently asked questions
What is the best image format for the web?
For photos, AVIF gives the smallest files (40–60% smaller than JPEG), with WebP as a widely-supported fallback (~96% of browsers) and JPEG as the universal default. Use PNG for graphics, logos and anything needing transparency.
What's the difference between lossy and lossless image formats?
Lossless formats (PNG, TIFF) keep every pixel exactly but produce larger files. Lossy formats (JPG, WebP, AVIF) discard imperceptible detail to shrink files dramatically — ideal for photos and the web.
How do I reduce an image's file size?
Convert to a compressed format like JPG, WebP or AVIF, and lower the quality setting slightly. At 80–90% quality the difference is invisible while files shrink 60–80% versus PNG.
