Why Convert JPG to WebP?
WebP files are typically 25-35% smaller than JPG at visually identical quality, and every current browser can display them. Converting a site's whole image folder to WebP is one of the cheapest page-speed wins available, and it feeds directly into better Core Web Vitals.
Common uses: website image folders, WordPress media libraries, product catalogues, blog assets, page-speed optimisation.
How to Batch Convert JPG to WebP
- Add your files — drag and drop the whole selection, click to browse, or paste. Add as many as you like.
- Output is already WebP — adjust the quality if you want, or switch format at any time.
- Convert — a progress bar tracks the batch, and each row shows its new size and savings.
- Download — save files one by one, or press Download all for a single ZIP.
No File Limit, and Nothing Uploaded
Most online bulk converters cap free users at 10, 20 or 50 files, because each image has to travel to their servers and back — and several keep your files on those servers for an hour or more before deleting them. This tool converts on your own machine, so there is no artificial cap and no upload at all. That is faster, and it means personal photos and client work stay yours.
Is It Safe and Private?
Yes — every file is decoded and re-encoded locally in your browser. Your images are never uploaded, never copied to a remote server, and never stored after you close the tab.
