Screenshots and exported mockups arrive as PNG and they are heavy: a full page capture routinely passes several megabytes before anyone has scrolled. Re-encoding as WebP tends to cut that by two thirds while leaving the transparent areas transparent. The encoder is compiled into this page, so an unreleased design stays on the machine that made it.
Frequently asked questions
- Does WebP handle transparency the way PNG does?
- It does, with the same eight bit alpha channel. A button asset or an icon with soft edges comes through with those edges intact.
- Is the WebP written lossless or lossy?
- This page writes lossy WebP, which is where the size saving comes from. Interface text stays sharp at the quality used, but a pixel exact archive copy is a reason to keep the PNG.
- Which browsers will display my WebP images?
- Every browser that still receives updates, and that has been true since 2020. The only visitors who miss out are running software old enough to have larger problems.
