FAQ

Common questions about PNG to AVIF.

How do I convert PNG to AVIF?
Drop your PNG file (or a whole folder) onto the converter. The browser decodes the PNG and re-encodes it as AVIF, then gives the file back to download. No upload, no signup, no install. For multiple files, they bundle into a single ZIP.
Is the PNG to AVIF converter really free?
Yes. No accounts, no daily caps, no per-file size limit, no watermark. The whole conversion runs in your browser, so there is nothing to ration.
Do my PNG files upload anywhere?
No. The PNG decoding and AVIF encoding both happen on your device. Nothing uploads, nothing is logged. Close the tab and the files are gone.
What's the difference between PNG and AVIF?
PNG is lossless and supports transparency, which makes it ideal for logos, screenshots, and graphics. PNG photos are usually 5 to 10 times larger than JPEG. AVIF is the newest format, roughly 50% smaller than JPEG at the same quality, with transparency and HDR support. Browser support is strong in 2026, but some older tools and email clients still cannot open it. Converting PNG to AVIF makes sense when you need AVIF's compatibility or features for your target platform.
Can I batch convert many PNG files at once?
Yes. Drop a whole folder or multi-select files. Each one converts in turn and the AVIF files bundle into a single ZIP for one-click download.
