Developers adopt WebP for Lighthouse scores and bandwidth savings.
Encode locally
Before CI, run PNG to WebP or JPG to WebP on marketing assets. Tune quality in the UI, no fixed file-size gate.
Decode for stakeholders
WebP to PNG when design needs PNG in Figma handoffs. WebP to JPG for email attachments.
Canvas API
Modern browsers encode WebP via canvas.toBlob—our tool wraps that client-side, same as production would.
Don't forget fallbacks
Always ship JPG/PNG fallbacks for email clients and ancient browsers.
