Is my image uploaded anywhere?

No. Conversion runs entirely in your browser using the Canvas API; the file never leaves your device.

Why is AVIF not offered?

Browser support for encoding AVIF is still unreliable. PNG, JPEG, and WebP are produced natively and consistently.

Convert between PNG, JPEG, and WebP right in your browser. Pick a format and quality, then download — the file never leaves your machine.

PNG is lossless (quality is ignored). AVIF is not supported by browser encoders.

Upload anonymously for a permanent URL — or use the API to convert on the fly from a URL.
