How it works
Add your PNG file
Drag a PNG file onto the drop zone, or click to browse. You can select several at once.
Choose your settings
Adjust the quality slider if you want a smaller file or a sharper result. 80 suits most photographs.
Download the AVIF
Conversion runs on your device as soon as each file is added — no upload, no queue. Download each result when it is ready.

Will converting PNG to AVIF make the file smaller?
Usually, yes. A 12-megapixel photo is around 14 MB as PNG and around 1.4 MB as AVIF — about 90% smaller. Because AVIF is lossless the result depends entirely on the image content — flat colour and text compress far better than photographic detail.
Does converting PNG to AVIF lose quality?
A little, by design. PNG is lossless and AVIF is lossy, so some detail is discarded in exchange for a much smaller file. At quality 80–90 the result is visually indistinguishable from the original for photographs. For screenshots, logos or anything with sharp text, stay with a lossless format instead — lossy compression creates visible halos around hard edges.
Is transparency preserved when converting PNG to AVIF?
Yes. Both PNG and AVIF support an alpha channel, so transparent and semi-transparent pixels carry across unchanged — a logo with a cut-out background stays cut out, and soft drop shadows keep their gradient rather than picking up a white halo. Because AVIF can compress lossily, a very hard edge against transparency may pick up slight softness at high compression; keep quality at 85 or above for cut-out graphics.
Should I use AVIF or WebP?
AVIF files are typically 25–35% smaller than WebP at the same quality, which is a real win on image-heavy pages. The trade-offs are much slower encoding and a support floor of Safari 16.4 (March 2023), so a small share of visitors cannot see it. Serve AVIF with a WebP fallback via a <picture> element if you want both.

On a typical 12-megapixel phone photo, the AVIF output comes out about 90% smaller than the PNG original. These are order-of-magnitude figures for one kind of image — your own results will vary a great deal, because flat colour, text and line art behave nothing like photographic detail, and the quality slider moves the figure substantially.
What to watch out for
- Encoding is computationally expensive and noticeably slow
- Requires Safari 16.4+ (2023), so a small share of users still miss it
- Sparse support outside browsers — most desktop editors cannot open it
About the two formats
PNG stores every pixel exactly as it was, with no generation loss no matter how many times you re-save it. That fidelity is why it dominates screenshots, logos and UI assets, and also why it is the wrong choice for photographs — lossless compression simply cannot get a 12-megapixel photo down to a reasonable size.
AVIF currently produces the smallest files of any widely supported format — commonly half the size of JPEG at the same perceived quality, with excellent handling of gradients and noise. The cost is encoding time, which can be seconds per image rather than milliseconds, and support that only became universal with Safari 16.4 in 2023.
Other conversions
Everything runs on your device — nothing is uploaded, so there is no size limit, no queue and no copy left on a server afterwards. There is more on how browser-based conversion works if you want the detail. Otherwise, browse every image tool, or convert AVIF back to PNG.
