Both are modern formats that produce much smaller files than PNG or JPG. WebP is supported in virtually every current browser and is a safe default. AVIF usually compresses even better at the same quality but is slower to encode and supported in fewer browsers. Squish detects what your browser supports and tells you on the settings bar.
You can convert PNG, JPG/JPEG and GIF images into WebP or AVIF. Add files by dragging and dropping, pasting from the clipboard, or browsing — and convert many at once.
Yes. Re-encoding through the canvas strips EXIF and GPS metadata, so location and camera details are removed from the output files.
Yes. After your first visit, Squish is cached on your device and continues to work without an internet connection. You can even install it as an app from your browser's menu.
