How to convert JPG to WebP
- Drop the JPG.
- Pick a quality.
- Press Convert and download the WebP.
What happens to your file
WebP encodes the same picture in fewer bytes than JPEG at equal visual quality — typically 25–35% fewer. Every current browser displays it.
Older desktop software and some upload forms do not accept WebP; convert back with WebP to JPG if one refuses.
Questions
Is WebP better than JPG?
Smaller at the same quality, and it supports transparency. Compatibility outside browsers is the only reason to keep JPG.
Do it once, not on every form
A form that wants a square JPEG under 240 KB says so on the page. The Fylane extension reads that, fits your photo to it, and puts it in the field — without you working out what 240 KB looks like.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
