Convert PNG to AVIF
Convert PNG to AVIF free in your browser: upload a .png file above and download it as .avif in seconds. No signup, no watermarks. A little, yes — AVIF is a lossy format, so the encoder discards data it considers invisible. At typical quality settings the difference is imperceptible for photos. If you plan to edit the image further, keep a copy of the PNG original.
Upload a .png file and download it as .avif in seconds. PNG is lossless format with transparency support, while AVIF is next-generation format with superior compression — below you can see exactly what changes in the conversion and whether switching makes sense for your image.

Should You Convert PNG to AVIF?
Conversion changes how your image is stored, not what it shows. Switching from PNG to AVIF trades one set of strengths for another, so it helps to know which side of that trade you are on.
Good reasons to switch
- ✓Best compression ratio
- ✓HDR support
- ✓Supports transparency
- ✓You need the file in a program or platform that only accepts .avif
Better off staying with PNG
- ✗Lossless quality — conversion does not remove this trade-off
- ✗Transparency support — conversion does not remove this trade-off
- ✗Universal support — conversion does not remove this trade-off
- ✗Nothing about your current workflow requires .avif
What Changes When You Convert
Quality
AVIF compresses lossily, so the output is slightly degraded compared to your lossless PNG original. For photos the difference is usually invisible at normal quality settings; for text and sharp edges it can show sooner.
Transparency
Transparency is preserved when converting between these two formats.
Animation
The output is a still image. To animate it you would need dedicated frames or an animated source.
File size
File size depends on content: AVIF files are typically around 50% smaller than JPEG at the same quality, while PNG files are compact for flat graphics and screenshots, large for photographs.

How the Converter Works
- Upload — drop your .png file into the tool above. It is processed temporarily and never shared.
- Convert — the file is re-encoded as .avif with sensible default quality settings.
- Download — grab the finished .avif file. Nothing is stored after processing.
