PNG to AVIF Converter

PNG graphics and screenshots converted to AVIF routinely shrink 80–90%, with transparency intact. If your destination supports AVIF, this is the most aggressive size reduction available from any mainstream format, done locally in your browser.
AVIF is the current high-water mark for image compression, and PNG is where it has the most room to work. A large lossless PNG carries far more data than any screen needs, so re-encoding it into AVIF, which keeps the alpha channel and adds 10-bit colour, produces some of the biggest size drops you will see anywhere, provided the place you are sending the image can display the format.

Maximum compression, if support allows
This is the tool to reach for when a PNG graphic is bound for a modern audience and you want the smallest possible file: hero images, illustrations, and screenshots on a current site all benefit. AVIF keeps the transparency you needed PNG for while typically landing another 15–25% smaller than even WebP.
The trade-offs are encode time and reach. AVIF takes longer to encode than WebP, a real few seconds on large batches, and while every current browser decodes it, some older webviews and CMS pipelines still stumble. If your destination is uncertain, WebP is the safer default; when you control the environment and it supports AVIF, this is the most aggressive win available.
Frequently asked questions
Does AVIF support transparency?
Yes, a full alpha channel, plus 10/12-bit color depth and HDR, capabilities PNG has partly and JPG entirely lacks. Transparency survives this conversion exactly.
How is this different from PNG to WebP?
Both keep transparency; AVIF typically lands another 15–25% smaller than WebP. The trade-off is encode time and slightly patchier support in older environments. For maximum compression with a modern audience, AVIF wins.
Is AVIF lossless?
It can be (AVIF supports a lossless mode), but this converter uses lossy encoding with a quality slider, which is what virtually all web use-cases want. At high quality settings, results are visually indistinguishable from the source.
