Questions & answers

Why switch JPGs to WebP?

WebP files are clearly smaller than JPGs at the same visible quality, so pages load faster and use less data – especially on phones.

Which WebP quality setting should I choose?

75–85% is right for most website photos. Use 90% or above for portfolios where every detail counts.

Can I upload WebP to WordPress and other CMSs?

Yes. WordPress, Shopify, Squarespace, Wix and most modern platforms accept WebP directly.

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.
