What is AVIF to PNG conversion?
This tool converts AVIF images into the PNG format, entirely in your browser with no upload. AVIF is a modern, highly efficient image format based on the AV1 codec. It offers excellent compression with transparency and HDR support, but is only opened by newer browsers and apps. PNG is a lossless format with transparency support, so quality never degrades when you save. It is ideal for logos, icons, screenshots with text and images with transparent backgrounds, but files tend to be larger.
How to use it
- Select or drop in your AVIF image.
- The tool converts it to PNG locally, instantly.
- Click Download to save the PNG file.
When should you convert AVIF to PNG?
AVIF compresses extremely well, but support is still limited outside the newest browsers, so you may need a more compatible format.
Convert AVIF to PNG when you need lossless quality or a transparent background — for cut-outs, logos or assets you will edit further. The trade-off is that PNG files are usually larger than AVIF.
AVIF vs PNG: key differences
| Property | AVIF | PNG |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | Yes | Yes |
| Best for | Modern web images needing maximum compression | Logos, icons, screenshots, transparent graphics |
When does converting AVIF to PNG make sense?
Convert AVIF to PNG when you plan to edit the image and want to keep every detail or its transparency. PNG is lossless, so it won't re-compress edges and text the way JPG does, and it fully supports an alpha channel — ideal for icons, UI assets, or cut-out illustrations you'll open in Photoshop or Figma. Be aware, though, that a PNG is not a little larger than the original AVIF but many times larger, and we measured how much: our photo went from 122.3 KB to 1.95 MB, and — counter-intuitively — the biggest multiplier was not the photo at all but the flat illustration, 3.2 KB to 90.6 KB, up 2704%. If the image is really a photo and you don't need a transparent background, converting to JPG or WebP instead will be far more space-efficient and practical.
This page’s growth lands within 4% of the original file — that closes a loop
The AVIF of that photograph in our corpus is 122.3 KB, and it was encoded from a 1.88 MB PNG in the first place. Convert the AVIF back here and you get 1.95 MB (+1532%) — within 4% of that original PNG. The closed loop says far more than the percentage alone: those 122.3 KB of AVIF were carrying a picture that costs nearly two megabytes to store losslessly, roughly 16× compression. So the +1532% on this page is not our tool going wrong; it is PNG faithfully turning everything AVIF saved back into bytes. The UI screenshot row is more extreme still: 1.4 KB → 36.5 KB (+2442%), and the illustration 3.2 KB → 90.6 KB (+2704%). The takeaway: going back to PNG pays off only when you need an editable working file that will not be re-compressed lossily again. For shipping, keep the AVIF or take the WebP route.
