Why convert JPG to WebP?
Convert JPG photos to WebP for noticeably smaller files at the same visual quality — great for speeding up a website.
What is JPG?
JPG (also written JPEG) is the world’s most common photo format. It uses lossy compression to make photographs very small, but it can’t store transparency and re-saving repeatedly slowly degrades quality.
What is WebP?
WebP is a modern image format from Google that’s typically 25–35% smaller than JPG or PNG at similar quality, with support for both transparency and animation. Some older software still can’t open it.
Is it private?
Completely. Unlike most “online converters” that upload your images to a server, this tool converts each JPG fileright inside your browser. Your images are never uploaded, stored or seen by anyone — not even us. It even keeps working offline once the page has loaded.
Frequently asked questions
Are my JPG files uploaded anywhere?
No — the conversion runs in your browser, so your files never leave your device.
Is it really free?
Yes: no sign-up, no watermark, and no limit on how many files you convert.
Can I convert in bulk?
Yes — add many JPG files at once and download them together as a ZIP.
