Will my PNG files be uploaded to a server when using this converter?

No, files are processed entirely in your browser and never uploaded, stored, or deleted from a server because they never leave your device.

Can I convert multiple PNG files at once?

Yes, you can drop in as many PNG images as you like, and they all come out as AVIF in a batch conversion with no file size limit.

What happens if my PNG image has transparency?

Formats without transparency get a clean white matte instead of the black edges most converters leave behind.

Is there a limit on the number of files I can convert?

There is no file size limit and no sign-up required; you can add multiple files and convert them all at once.
