Convert JPG to WebP
Serve the same photo in fewer kilobytes. WebP encodes photographs more efficiently than JPG, and this tool re-encodes on your device — the stamp tells you precisely what you saved.
100% private — this tool runs in your browser. Your file is never uploaded to any server.
How it works
JPG and WebP are both lossy photo formats, but WebP’s encoder is a generation newer and squeezes the same visual quality into fewer bytes. Converting means decoding your JPG and re-encoding it — done here by your own browser, so the photo never leaves your device. One honest note: re-encoding an already-compressed JPG cannot recover detail the JPG discarded, so convert from the best copy you have. EXIF metadata (camera model, GPS position) is not carried into the output — for a photo you are about to publish, that is usually a feature.

Frequently asked questions
How much smaller is WebP than JPG?
For photographs at comparable visual quality, expect roughly 20–40% smaller files. Your exact result depends on the photo and the quality setting, which is why the stamp reports the real numbers for your file.
Does converting JPG to WebP lose quality?
Any re-encode of a lossy format discards a little information. At the Highest setting the difference is invisible at normal size. What conversion cannot do is restore detail your JPG never had — always convert from your best original.
Is the EXIF data (location, camera) kept?
No — the output contains pixels only. GPS coordinates, camera model and timestamps are left behind, which is generally what you want before publishing a photo publicly.
Why would I convert JPG to WebP at all?
Page speed. Smaller images load faster and score better on Core Web Vitals, and image weight is usually the largest part of a page. Converting your product or blog photos to WebP is one of the cheapest speed wins available.
Can I convert a whole folder of photos?
Select or drop as many as you like — each converts in turn with its own download button and saving readout. Very large batches are limited only by your device’s memory.
Will the converted photo look different on any browser?
No. All current browsers render WebP natively, so the photo displays exactly as encoded, on desktop and mobile alike.
Are my photos uploaded to convert them?
No. Decoding and re-encoding happen inside your browser tab. Nothing is transmitted, so there is no server copy of your photos to retain or leak.
What quality setting should I choose?
Balanced (0.82) for web pages, listings and email. Highest if you are archiving or expect the image to be enlarged. Smallest when raw kilobytes matter more than close-up fidelity — thumbnails, chat, low-bandwidth audiences.
