  3. Convert, then download each AVIF file or all of them as a ZIP.

How it works

PNG is a lossless format with full transparency support. It is ideal for screenshots, logos and graphics with sharp edges, but photos are much larger than as JPG or WebP.

AVIF is a newer format based on the AV1 video codec. It often produces the smallest files at a given quality and supports transparency, but encoding is slower and support in older software is limited.

AVIF uses lossy compression: the quality setting trades file size against fine detail. 80–90% is a good default for photos. Converting re-encodes the image, which removes EXIF metadata such as camera details and GPS location.

Frequently asked questions

Are my images uploaded?

No. The browser decodes and re-encodes every image on your device, so the files never leave your computer or phone.

Will converting PNG to AVIF reduce quality?

AVIF uses lossy compression: the quality setting trades file size against fine detail. 80–90% is a good default for photos.

How many files can I convert at once?

It depends on your plan's image limits, shown on the Pricing page. A free account allows more files per batch than visiting without an account.
