Convert PNG to AVIF Locally — The Fastest Way on Mac
AVIF delivers up to 50% smaller files than WebP and up to 80% smaller than PNG — at the same quality. Convert your PNG files to AVIF locally with TinyPixels, no upload required.

Why AVIF beats WebP and PNG
AVIF is the most advanced image format available today. Based on the AV1 video codec, it achieves compression ratios that leave older formats behind. A 500KB PNG might become a 50KB AVIF with virtually identical visual quality — a 90% reduction that dramatically speeds up websites and saves storage.
| Format | Typical size (same quality) | Transparency |
|---|---|---|
| PNG | Baseline (100%) | ✅ Yes |
| JPEG | ~30% smaller | ❌ No |
| WebP | ~50% smaller | ✅ Yes |
| AVIF | ~70–80% smaller | ✅ Yes |
Converting PNG to AVIF is especially impactful for designers and developers with large icon libraries, product image catalogs, or illustration assets — the kinds of files that are typically large PNGs and rarely need to be perfectly lossless for web delivery.
Why convert locally?
AVIF conversion is computationally intensive. Online converters throttle your conversion speed, impose file size limits, and — by definition — require you to upload your files to their servers. TinyPixels runs the conversion engine on your machine, using all your CPU cores in parallel. On Apple Silicon Macs, this is significantly faster than any cloud-based tool.
Also converts to WebP, JPEG, and more
TinyPixels supports all major format conversions in one app. Convert PNG to AVIF, AVIF to JPEG, JPG to WebP — whatever you need, locally.
Frequently asked questions
What is AVIF format?
AVIF (AV1 Image File Format) is a next-generation image format based on the AV1 video codec. It delivers significantly better compression than both JPEG and WebP — often 50% smaller files at the same visual quality — while supporting HDR, wide color gamut, and transparency.
Does PNG to AVIF conversion cause quality loss?
AVIF supports both lossy and lossless modes. For web use, lossy at 80–85% quality is visually indistinguishable from the original PNG while being dramatically smaller. TinyPixels gives you full control over the quality slider, so you choose the trade-off.
Is AVIF supported everywhere in 2026?
AVIF is now supported in Chrome, Firefox, Safari (since macOS Ventura / iOS 16), and Edge. As of 2026, global browser support exceeds 93%. For maximum compatibility, you can use AVIF with a WebP or JPEG fallback using the HTML <picture> element.
Can I bulk convert PNG to AVIF?
Yes. TinyPixels is built for bulk conversion. Drop an entire folder of PNG files and TinyPixels will convert all of them to AVIF simultaneously using all your CPU cores — no upload, no waiting for a cloud queue, fully offline.
