Converting JPG to WebP
This tool converts JPG images to WebP. JPG (JPEG) is the most widely supported photo format, using lossy compression for small files that open everywhere. WebP is a modern format from Google that is roughly 25–35% smaller than JPG or PNG at the same quality, with transparency and animation support. You can convert one image or bulk-convert hundreds at once, entirely inside your browser — your files are never sent to a server.
How JPG to WebP works
How to convert JPG to WebP
- Add your JPG image(s). Drag and drop them onto the box, or click Add Image(s) — one file or hundreds at once.
- Choose your options. Set the quality and an optional size — the whole queue re-converts instantly as you adjust.
- Download. Save each WebP file with its Download button, or click Download All to get the whole batch as a ZIP.
One image or a whole batch — same page
There is no separate bulk tool. Drop a single JPG and get one clean WebP; drop an entire folder and they all convert in a queue, each shown as a card with a live thumbnail and the exact before-and-after file size.
Why convert JPG to WebP?
Converting JPG to WebP shrinks file size dramatically, so pages load faster, use less bandwidth and score better on Core Web Vitals — a real SEO advantage.
Is it private?
Yes — conversion runs entirely in your browser using its built-in image engine. Your files are never uploaded, so the tool works offline and keeps confidential images private.
