Shrink your PNGs without the quality hit. Convert PNG to modern AVIF right here in your browser — much smaller files, transparency preserved.
Your files never leave this device.png · up to 10 at once · 50 MB each
Four steps, a few seconds, zero uploads.
Drag images onto the box above, or click Browse to pick them from your device.
Pick an AVIF quality level — higher keeps more detail, lower makes smaller files. The default suits most images.
Latch encodes each PNG to AVIF with the AV1 codec, right in your browser — instantly and offline.
Save them one at a time, or grab everything at once in a single zip. That's it.
PNG is lossless and universal, but that comes at a cost: the files are large, which slows down web pages and eats storage. AVIF uses the modern AV1 codec to pack the same image into a fraction of the size — often 50–90% smaller — while staying visually indistinguishable at sensible quality settings. For website images, app assets, or anything you're shipping at scale, that's a big win for load times and Core Web Vitals.
Crucially, AVIF keeps the alpha channel, so PNGs with transparency convert without losing their transparent areas — something JPG can't do. That makes it a true drop-in replacement for most PNGs on the web.
The one trade-off is reach: very old browsers and some legacy apps don't open AVIF yet. If you need a file that opens literally everywhere, keep the original — or go the other way with AVIF to PNG.
AVIF files are typically 50–90% smaller than PNG at visually similar quality, thanks to the modern AV1 codec. Savings are largest on photographic or complex images; simple graphics with few colours see smaller gains.
Yes. AVIF supports a full alpha channel, so any transparency in your PNG is preserved in the AVIF output — you get the smaller file without losing transparent areas.
This tool encodes lossy AVIF, which gives the biggest size savings. Raise the quality slider for near-lossless results. Because it re-encodes the image, very fine detail may change slightly at low quality — increase quality if you need an exact match.
All current browsers — Chrome, Edge, Firefox, and Safari 16 and later — display AVIF, and it's widely supported across the web. Some older apps, devices, or operating systems may not open it yet, so keep a copy of the original if you need broad compatibility.
No. Every PNG is encoded to AVIF by your own browser. Nothing is sent to a server — in fact, the tool keeps working even with your Wi-Fi switched off.
