PNG is logos, screenshots, graphics and anything with transparency, but not always the right fit. Converting to AVIF fixes that: smallest files of any common format.
Drop one PNG or a hundred — they’re converted inside your browser, so even private photos are never uploaded anywhere.

Good to know before converting PNG to AVIF
- AVIF files are smaller, but double-check that the app or site you’re uploading to accepts AVIF.
- Hidden data like GPS location and camera details is left out of the converted file.
What is PNG?
PNG keeps every pixel exactly as it is and supports transparent backgrounds. That makes it perfect for logos, screenshots and cut-outs — but photos saved as PNG are often 5–10× bigger than the same photo as JPG.
What is AVIF?
AVIF is the newest mainstream image format, based on the AV1 video codec. It squeezes photos dramatically smaller than JPG while keeping them sharp, and supports transparency and HDR. It’s still new, so many apps and websites don’t accept it yet.
How to convert PNG to AVIF
- Drop your PNG files (or paste with Ctrl+V).
- AVIF is already selected — adjust quality if you like.
- Download one by one or all as a ZIP.
Frequently asked questions
Does converting PNG to AVIF reduce quality?
Only very slightly. AVIF is lossy or lossless; at the default quality the difference is practically invisible. Raise the quality slider for maximum fidelity.
Can I convert many PNG files at once?
Yes — drop as many as you like and download them all as one ZIP.
Are my images uploaded to a server?
No. Everything happens inside your browser on your own device. Your images are never uploaded, stored or seen by anyone — check your browser's Network tab, or turn on airplane mode after the page loads and see that it still works.
Is it really free?
Yes. No sign-up, no watermark, no daily limits and no paid “HD” downloads.
Do downloads still contain my location?
No. Every file you download is saved without hidden metadata like GPS location, camera serial number or owner name.
