PNG to AVIF Converter
PNG graphics - screenshots, icons, diagrams, logos - are often the heaviest assets on a page. Converting them to AVIF delivers huge savings: AVIF lossless consistently out-compresses PNG, and lossy AVIF can shrink graphic content by 70-90% while keeping text and edges razor sharp. AVIF also supports full alpha transparency, so your cut-outs and overlays keep their clean edges.

PixConvert converts PNG to AVIF locally in your browser. There is no upload, no account, and no watermark - drag in your files, choose lossless or lossy mode, and download the results. The comparison preview lets you verify that fine text and thin lines survive compression before you commit.
Why convert PNG to AVIF?
Lossless that beats PNG
In lossless mode AVIF packs the same pixels into a smaller file than PNG, typically 10-30% smaller. Zero visual change, pure savings.
Dramatic lossy savings
For screenshots and UI graphics, lossy AVIF at quality 60-80 often looks identical while cutting file size by an order of magnitude.
Transparency included
Like PNG, AVIF supports 8-bit alpha. Icons and composited graphics keep their transparency after conversion.
Sharp text and edges
AV1's intra prediction handles flat colors, text, and hard edges exceptionally well - exactly what PNG-style content is made of.

Frequently asked questions
Is AVIF lossless smaller than PNG lossless?
Yes, on virtually all real-world images AVIF lossless produces smaller files than PNG, typically 10-30% smaller, with identical pixel data.
Will small text stay readable?
In lossless mode, always. In lossy mode, AVIF handles text remarkably well, but check the preview - if you see ringing around tiny text, raise the quality or switch to lossless.
Does AVIF keep PNG transparency?
Yes. AVIF supports a full alpha channel, and PixConvert preserves it during conversion.
AVIF or WebP for PNG replacement?
AVIF compresses better, especially for graphics and screenshots. WebP has marginally broader support in very old browsers, but for modern audiences AVIF is the stronger default.
Can I convert back from AVIF to PNG later?
Yes - use the AVIF to PNG converter on this site. If you used lossless mode, the round-trip is pixel-perfect; lossy conversions cannot recover information that was discarded.
