This converter needs JavaScript. It runs entirely in your browser and nothing is uploaded.
Looking for video or audio? Those live on the video pages. Word, Excel and other documents need a server-side engine, so I don't offer them — CloudConvert handles those.
Private by design
Files are read and written on your device. The page never uploads them, so there is nothing to delete later.
No limits, no watermark
Convert as many files as you like, as often as you like. There is no queue and no daily cap.
Fast and offline-capable
Your browser does the work, so a batch finishes in seconds and keeps working without a connection.

About converting JPG to WebP
WebP at the same visual quality is typically 25 to 35 percent smaller than JPG, and that gap is the whole reason to convert. Smaller images mean faster pages, better Core Web Vitals, and lower bandwidth bills. Photos are where the saving is biggest.
The quality slider works like a JPG quality setting. 80% WebP looks about like 90% JPG at a fraction of the size. Because the source is already a lossy JPG, keep the setting reasonably high; stacking two heavy compressions is where artefacts start to show.
Batch-friendly and completely local. Nothing is uploaded, so a folder of product photos converts as fast as your computer can manage.
Frequently asked questions
Should I convert all my website images to WebP?
Almost always yes for photos and illustrations. Keep SVG for icons and logos, and keep a PNG or JPG fallback only if you must support browsers from before 2020.
Why does the WebP sometimes come out larger than the JPG?
A very heavily compressed JPG has already discarded most of its detail, and re-encoding the artefacts can cost more bytes than the original. Lower the WebP quality or leave that image as JPG.
Does converting to WebP keep EXIF data?
No. The re-encoded file has no camera metadata or GPS location, which is often what you want for images going onto a public website.
