What happens when you convert PNG to AVIF
| Compression | Lossless → Lossy or lossless |
|---|---|
| File size | Usually far smaller: often under a fifth of the size for photos |
| Transparency | Kept |
| Metadata | EXIF, GPS location and camera data are not copied to the new file |
| Opens in | Chrome, Edge, Firefox, Safari 16+ and Windows 11 with the AV1 extension; most editors and CMSs do not yet |
Sizes are typical values; your files will vary with content and settings.
PNG Portable Network Graphics
PNG stores pixels with lossless DEFLATE compression and a full 8-bit alpha channel. It is the safe default for screenshots, logos, UI assets and anything with sharp edges or text, because every pixel survives exactly as drawn.
PNG converterAVIF AV1 Image File Format
AVIF stores images with the AV1 video codec. It usually beats WebP on file size, handles HDR and wide colour, and supports transparency. Chrome, Firefox, Edge and Safari 16+ display it.

Why convert PNG to AVIF?
PNG files usually come from screenshots, design tools and image downloads, where lossless storage keeps edges crisp. Photographs saved as PNG are often 3 to 10 times larger than the same photo as JPG or WebP. Choose AVIF for the smallest web images, after checking that your CMS or upload target accepts it.
PNG to AVIF settings
Use the quality slider to balance size against detail; 80 to 90 percent is a good default for AVIF. You can also cap the width and height, which resizes large photos in the same step.
Frequently asked questions
Will the AVIF lose quality?
AVIF uses lossy compression, so some fine detail is discarded to make the file smaller. At the default quality setting the difference is very hard to see. Raise the quality slider if you need the result to stay closer to the PNG original.
Is transparency kept when converting PNG to AVIF?
Yes. AVIF supports transparency, so transparent areas in your PNG stay transparent.
Will the AVIF be smaller than the PNG?
Usually much smaller for photos: as a rough guide, the AVIF comes out at around 5% of the PNG's size, depending on the quality setting.
