PNG vs AVIF at a glance
How the two formats compare, so you know what to expect.
PNG
Your filesA lossless format that keeps every pixel exactly. Great for screenshots, logos and anything with text or sharp edges.
Best for Screenshots, logos, diagrams, cut-outs with transparency, and master copies you will edit again.
AVIF
What you getThe newest format here, built on the AV1 video codec. It makes the smallest files at a given quality.
Best for Websites where every kilobyte counts, and high-quality photos at tiny sizes.
| PNG | AVIF | |
|---|---|---|
| Compression | Lossless | Lossy or lossless |
| Transparency | Yes | Yes |
| Animation | Rarely (APNG) | Yes |
| Photo file size | Often 3–5× a JPG | About half a JPG |
| Opens in | Everywhere | Modern browsers, fewer apps |
Questions, answered
Will converting PNG to AVIF reduce quality?
AVIF is lossy: it trades a little detail you’re unlikely to notice for a much smaller file. At the default quality most people can’t tell the difference, and you can raise the quality if you want to be extra careful.
Will the AVIF be smaller than the PNG?
Usually, yes. AVIF compresses images more efficiently than PNG, so most files get noticeably smaller. You’ll see the exact size of every file, and how much you saved, as soon as it’s converted.
What happens to transparent backgrounds?
They stay transparent. AVIF supports transparency with smooth edges, so logos, icons and cut-outs convert cleanly.
Can I convert lots of PNG files at once?
Yes. Add as many as you like: they’re converted side by side on your device, and you can download them one by one or all together as a .zip.
Do my images leave my device?
No. The PNG to AVIF conversion runs entirely in your browser, so your images are never sent anywhere. There’s no sign-up and no limit on how many you convert.
