Convert images to AVIF.
Convert JPEG and PNG to AVIF for the smallest files you can get. The encoding runs on your device with WebAssembly, so nothing is ever uploaded, and there is no account to create.
Compression settingsApplied to every image
Format
Auto keeps each image in its original format, re-compressed smaller.

Quality

FAQ
Good to know.
Is AVIF ready for production websites?
Yes. Every major browser supports AVIF. If you still need to cover very old browsers, pair it with a WebP or JPEG fallback using the picture element.
How small will my images get?
Usually 40 to 60 percent smaller than JPEG. Use the before and after slider to confirm the quality before you download.
Does conversion happen on a server?
No. AVIF encoding runs entirely in your browser, so your images never leave your device.
