Are my images uploaded to convert to WebP?

No. The conversion to WebP runs locally in your browser, so your files never leave your device — it works offline too.

Why choose WebP over JPG or PNG?

WebP usually produces a smaller file than JPEG at the same visual quality, and unlike JPEG it can keep transparency, making it great for the web.

Does WebP keep transparency from a PNG?

Yes. Converting a transparent PNG to WebP preserves the transparency, while converting to JPG would fill it with white.

Is WebP supported everywhere?

WebP is supported by all modern browsers. If your device cannot encode WebP, the tool falls back to JPG automatically so you always get a working file.

Can I compress many images to WebP at once?

Yes. Add as many as you like; they are compressed together and you can download them all as a single ZIP.
