How PNG to AVIF under 200KB works

Need to convert PNG files to AVIF? PixelKit does it in one click, right in your browser. It runs a fast binary-search compression loop to land your file under 200KB without visible quality loss — the same technique professional photo tools use, but without asking you to sign up or upload anything. Because nothing is sent to a server, there is no upload wait, no file-size limit from a backend, and no privacy risk. Your photos, ID scans and documents stay on your device the entire time.

The tool works offline after the first page load, on mobile and desktop, and produces standard AVIF files accepted by portals, email clients and design apps. Just set the target to 200KB, drop your PNG file, and download the result. If the first pass lands slightly above 200KB, PixelKit automatically tries again with a tighter quality curve — so you always get the smallest file that still meets the limit.

No account, no watermark, no email gate. Just the file you need, at the size you need it.

Frequently asked questions

How do I compress PNG to under 200KB?

Drop your PNG file into the tool above, choose AVIF as the output, and set the target to 200KB. PixelKit automatically adjusts quality to land at or below the target — no manual slider work required.

Is this PNG to AVIF converter really free?

Yes. PixelKit is free to use with no watermarks, no file limits, and no account. The tool runs entirely in your browser, so there is no server cost that would justify a paywall.

Are my PNG files uploaded anywhere?

No. The conversion happens locally using your browser's canvas and Web Worker APIs. Files never leave your device, and nothing is stored after you close the tab.

What is the maximum PNG file size?

There is no server-side limit because there is no server. Very large files may be limited only by your device's available memory — usually several hundred MB on desktop and tens of MB on mobile.
