FAQ
Common questions
Why use WebP?
WebP often produces files 25–35% smaller than an equivalent JPEG or PNG at similar quality, which makes web pages load faster and improves Core Web Vitals. Smaller images also save bandwidth for you and your visitors.
Can this keep transparency?
Yes, when the browser exports the image as WebP with alpha support, transparent areas from a PNG are preserved. That makes WebP a smaller alternative to transparent PNGs for logos and overlays.
Do all browsers support WebP?
Every current major browser supports WebP. If you need to support very old browsers, keep a JPEG or PNG fallback, but for most modern sites WebP is safe to use directly.
Does the conversion happen privately?
Yes. The image is converted in your browser and is not uploaded, so your files stay on your device.
