PNG to AVIF Converter

Turn PNG graphics or photos into AVIF for modern web performance — entirely in your browser when AVIF encoding is available.

Encoded in your browser when AVIF writing is supported (modern Chromium). If encoding is unavailable, the converter explains and suggests WebP.

Why Convert PNG to AVIF?

Private by design

PNG → AVIF runs in your browser. Files are not uploaded to a remote conversion queue.

Ready for the next step

Convert when a site, editor, or teammate expects AVIF instead of PNG.

Practical quality

AVIF: varies. Lossy targets trade size for speed — preview when it matters.

Transparency aware

AVIF can keep transparent pixels when the source supports them.

What happens to image quality?

AVIF can carry alpha in supporting pipelines. Verify your delivery stack if transparent AVIF is required.

Tip

Confirm alpha looks correct on checkerboard and brand-colored backgrounds.

Does AVIF support transparency?

AVIF can store transparent pixels — AVIF supports transparency (including alpha where the codec/container allows). Keep a format with alpha when you need soft edges or overlays.

Frequently Asked Questions

More on quality loss: conversion quality guides · problem-solution guides

Does PNG to AVIF lose quality?

It can. AVIF is typically lossy, so encoding may discard detail for smaller files. Use higher quality/bitrate settings when fidelity matters, and keep the PNG master.

Does converting PNG to AVIF reduce quality?

Often yes at default lossy settings. Raise quality/bitrate for delivery, or stay on a lossless format when you still need a master.

Can you recover quality after converting?

Not from a lossy output alone. Return to the original master (or a better source). Converting to a lossless format does not resurrect discarded detail.

What is generational loss?

Damage that stacks when you decode and lossy-encode the same file over and over (for example JPG→edit→JPG). Edit from masters and export delivery formats once.

Where can I learn more about conversion quality?

Browse Format Convertly’s Quality guides for topics like whether conversion reduces quality, JPG↔PNG myths, WebP/MP3/MP4 tradeoffs, recovery limits, and generational loss — each links to the right converter.

Why is my PNG file so large?

PNG is lossless — photos saved as PNG stay huge. Convert photos to JPG or WebP (after resizing). Keep PNG for logos, UI, and transparency. Full guide: Why Is My PNG File So Large?.

Where can I find more problem-solution guides?

Browse the Guides hub for long-tail fixes — HEIC won’t open, PNG too large, PDF not searchable, video too large, WebP upload failures, and more — each links to the right converter or tool.

Can every browser create AVIF?

Not yet. Modern Chromium builds often can; others may decode AVIF but not encode it. Format Convertly checks support and will not silently save a fake .avif.
