Frequently asked questions
What is WebP?
WebP is a modern image format from Google that compresses photos and graphics much smaller than JPEG or PNG at the same quality — typically 25–35% smaller — which makes pages load faster.
Does my image get uploaded?
No. The conversion happens entirely in your browser using the Canvas API. Your image never leaves your device.
Which formats can I convert from?
Any image your browser can open — PNG, JPG/JPEG and GIF — converts to WebP. Use the quality slider to trade size against fidelity.
Why convert to WebP?
Smaller images are the single biggest win for Core Web Vitals on most small-business sites. Serving WebP instead of PNG/JPEG cuts page weight with no visible quality loss.
