Converting images, the short guide
How it works here
WebP to PNG, JPG to WebP, PNG to JPG, whatever to whatever, converted right in your browser and handed back in the format you wanted. Your files never leave your device. One action per image converted, and it is batch friendly: line up several images and convert them all the same way. Picking and previewing are free.
The two directions
Convert to WebP to shrink images for your website while keeping them sharp. Convert from WebP when some upload form refuses it: a screenshot stuck as a WebP becomes a friendly PNG here, which is the format every other tool and form on the internet accepts.
Which format when
PNG is the safe default almost everything accepts. JPG suits photos and keeps files small. WebP is the pick for your own website, where the smaller file loads faster and modern browsers all support it.
