Questions about PNG and WEBP

Is the transparency kept?

Yes, WEBP supports the alpha channel exactly like PNG.

Are my PNG files uploaded to a server?

No. The conversion from PNG to WEBP happens entirely in your browser, using your device’s computing power. Files aren’t sent or stored anywhere: when you close the page they’re gone from memory too.

How many files can I convert at once?

Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.

Does it work on iPhone and Android?

Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.

What quality should I choose for WEBP?

For photos to share or post online, a quality between 75 and 85 gives light files with no visible flaws. For print or archiving go up to 90-95.

Do I need an internet connection?

Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
