FAQ
Is this PNG to AVIF converter free, with no upload?
Yes. The image is decoded and re-encoded in your browser using a Canvas + Wasm pipeline — it never uploads. No signup, no watermark.
Will converting PNG to AVIF lose quality?
AVIF can store the image losslessly (or near-losslessly), so converting from PNG preserves visual quality.
Does it preserve transparency?
Yes — the output format supports an alpha channel, so transparent areas in the source are preserved.
What is the maximum file size or resolution?
Up to 50 MB per image. Resolution caps depend on browser memory; modern browsers handle 12000 × 8000 px without issue.
