Why convert PNG to AVIF?
AVIF's compression efficiency is the most aggressive of any mainstream image format. For graphics with limited color palettes — logos, icons, illustrations — AVIF's lossless mode often beats PNG by 30–40%. For photographic content with transparency (product cutouts, hero overlays), the lossy mode commonly cuts file size in half versus PNG.
The trade-off, as with all AVIF conversions, is encoding time: AVIF encoders do significantly more work than PNG encoders. But that work happens once during conversion, and every subsequent page load benefits. For static assets that get served thousands of times, the math is overwhelmingly in AVIF's favor.
Browser support now covers Chrome, Firefox, Edge, Safari 16.4+, and Opera. For maximum compatibility, serve AVIF inside a <picture> element with a WebP or PNG fallback.

PNG to AVIF — Frequently Asked Questions
Is the PNG to AVIF converter really free?
Yes — completely free, with no signup, no credit card, no watermarks, and no file count limits. The full feature set is available without any account.
Are my PNG files private?
Yes. Files are stored in a private directory outside the web root, never shared with anyone, and deleted immediately after you download your ZIP.
How many PNG files can I convert at once?
Up to 20 PNG files per batch, with a maximum of 25 MB per file. There are no limits on the number of batches you can run.
Does the converted AVIF keep the same image quality?
Quality is essentially indistinguishable from the PNG source at typical viewing sizes. AVIF uses lossy compression, but the quality settings are tuned for high fidelity, so the conversion produces visually identical results for almost all images.
Which browsers support AVIF?
Chrome, Firefox, Edge, Opera, and Safari (16.4 and later) all support AVIF. For the small remaining gap in coverage, serve AVIF inside a <picture> element with a WebP or JPG fallback.
