Why convert PNG to AVIF?
AVIF supports transparency and compresses much better than PNG, so it is a great choice for web graphics that would otherwise be heavy PNGs.
PNG is a lossless format with transparency support, ideal for logos, screenshots and graphics with sharp edges. AVIF is the newest web image format, based on the AV1 video codec. It often produces files around half the size of JPG.
Frequently asked questions
Does AVIF keep transparency?
Yes. AVIF supports a full alpha channel, so transparent backgrounds are preserved.
Are my images uploaded to a server?
No. Every image is processed inside your browser using WebAssembly. Nothing is sent over the internet, which also makes it fast and safe for private photos.
Is it really free? Are there limits?
Yes. It’s free with no sign-up, no watermark and no daily limit. Your own device does the work, so there is no server cost per image.
Is image quality affected?
The default quality setting produces results that look the same as the original. Move the slider to 95–100 for maximum quality.
Does it work on my phone?
Yes. It works in any modern browser on iPhone, Android, Mac, Windows and Chromebook. You can also add it to your home screen and use it offline.
