Frequently asked questions
How do I convert PNG to AVIF?
AVIF is currently one of the most space-efficient photographic formats in mainstream use, often producing smaller files than an equivalent WebP at matched visual quality. Converting a PNG export or screenshot to AVIF is worth it for anything headed to a modern website — every major current browser decodes AVIF natively.
Is this PNG to AVIF converter free?
Yes — completely free with no signup, no watermarks, and no file limits. The tool is open source and will stay free.
Do my PNG files get uploaded to a server?
No. Conversion runs entirely in your browser using WebAssembly. Your PNG files never leave your device, which also makes it faster than upload-based converters.
Will converting PNG to AVIF lose quality?
AVIF is a lossy format, so some compression is applied — you control the trade-off with the quality slider (default 65%). At 85% or above the difference is rarely visible.
Can I convert multiple PNG files at once?
Yes. Drop as many PNG files as you like — they convert in batch and you can download the results individually or as a single ZIP.
Is AVIF the right choice for every image?
It's strongest on photos and complex images with gradients and fine detail — the same content JPEG and WebP handle well. For flat-color graphics like icons or line art, PNG or SVG can still end up smaller; AVIF's advantage comes from how it handles photographic complexity, not simple graphics.
