Convert PNG to AVIF
PNG files are heavy because they store every pixel exactly. Converting to AVIF keeps the transparent background and usually removes most of the weight. Drop your .png files below; everything happens in your browser.

A PNG is lossless: it records the exact value of every pixel. That is ideal for a logo and wasteful for a photo, where neighbouring pixels differ slightly everywhere and nothing compresses well. A phone screenshot of a photo can easily weigh 5 MB as PNG.
AVIF is lossy by default and built for exactly that kind of content, so the drop is dramatic. The same image often comes out under 500 KB with no difference you can see at normal size.
Images that should stay PNG
Keep PNG for source files you will edit again, for pixel art, and for anything where an exact colour value matters, such as a brand swatch or a UI mock-up being measured by a developer.
Keep it too when the destination is not a browser. Print shops, presentation software and many document tools handle PNG reliably and AVIF poorly or not at all.
Frequently Asked Questions
Yes. AVIF has an alpha channel, so a logo or cut-out on a transparent background stays transparent. You do not get the white box that a JPG conversion produces.
It depends on the content. A photographic PNG often shrinks by 80–90%. A flat-colour logo or diagram shrinks less, sometimes 30–60%, because PNG is already efficient on that kind of image.
At quality 65 and above, yes for most images. Small text on a busy background is the first thing to soften, so zoom in with the comparison slider and raise the quality if edges look smeared.
For sharing on a website, yes. For documentation you will edit again, keep the PNG: it is lossless, so repeated saves never degrade it.
