Questions & answers

How much space does WebP save over PNG?

For photos and detailed graphics, often 50–90%. Simple flat artwork saves less, and the converter shows the exact size change for every file.

Will WebP show up in every browser?

Yes. Chrome, Safari, Firefox, Edge and every other modern browser display WebP, which is why it's recommended for faster pages and better Core Web Vitals.

Is transparency kept going from PNG to WebP?

Yes. WebP supports transparency, so see-through parts of the PNG stay see-through.

Do my files get uploaded anywhere?

Never. The work is done by JavaScript running in your own browser, on your own device. Nothing is sent to a server or kept anywhere, which makes it safe for personal photos and sensitive data – and it carries on working even on a patchy connection.

How many images can I convert, and how big can they be?

There's no cap on either. Convert as many as you want, as often as you want. Only your device's memory limits really huge batches, so if you have hundreds of high-resolution photos, do them in a few rounds.
