Convert PNG to AVIF

Convert PNG to AVIF for the smallest possible lossless-quality graphics. Lossless AVIF is smaller still than lossless WebP — but slower to encode.

AVIF's lossless mode compresses more aggressively than PNG or WebP. For typical graphic content the file drops another 15–25% below lossless WebP — meaningful on graphic-heavy pages.

AVIF encoding is 10–30× slower than PNG. For static site builds that cost is a one-time hit; for dynamic thumbnail pipelines it matters. Consider WebP if you're generating on the fly.

Frequently asked questions

How do I convert PNG to AVIF?
Drop your PNG file into the tool above. It's converted to AVIF in the browser and ready to download. Multiple files can be converted at once.
Why convert PNG to AVIF?
AVIF's lossless mode compresses more aggressively than PNG or WebP. For typical graphic content the file drops another 15–25% below lossless WebP — meaningful on graphic-heavy pages.
Is any quality lost when converting to AVIF?
Converting between lossy formats (like JPG to WebP) involves one round of re-encoding, so there is theoretically some quality loss — but at the default quality setting it's visually indistinguishable. Converting to a lossless format (PNG) doesn't lose data from the source.
Does the AVIF file work everywhere the PNG did?
Modern browsers, image editors, and platforms all support AVIF. Older tools (2015-era software, some third-party services) may not — if you need maximum compatibility, JPEG or PNG remain the safest fallbacks.
Are my files uploaded anywhere?
No. Conversion runs entirely in your browser using the Canvas API. Files never touch our servers, which matters for pre-publication work, client assets, or anything sensitive.
