Frequently asked questions

Are images uploaded?
No. Decoding and encoding happen entirely in your browser.
Why is PNG larger sometimes?
PNG is lossless; re-encoding from a lossy source cannot shrink as much as WebP or JPEG at lower quality.

Key concepts

WebP
A modern image format by Google that provides smaller file sizes than PNG and JPEG at comparable quality — supported by all modern browsers.
Lossless vs lossy compression
Lossless (PNG, WebP lossless) preserves every pixel exactly. Lossy (JPEG, WebP lossy) discards some data to achieve smaller file sizes.
