JPG to WebP online
Add a JPG and get a WebP, which is usually lighter at similar quality. Quality and size are adjustable, and your photos stay on your device.
Accepts JPG, PNG, WebP, HEIC and HEIF. Up to 25 files at once, 40 MB per file; up to 13 megapixels on mobile and 24 megapixels on desktop.
Why convert JPG to WebP
WebP was built for the web: at the same quality files are usually smaller than JPG, and pages with such images load faster. That is why site owners and online stores like it.
Before using it, make sure the site, program or service you upload to accepts WebP: some editors and print services cannot open it. Modern browsers support the format.

What changes when you convert
- This tool exports a still image. Live Photo motion, depth data and HDR information are not preserved; HEIC is rendered as a standard SDR image.
- EXIF and GPS metadata from the source are not copied to the new file. Keep your original if you need capture information.
- JPG and lossy WebP can change fine details. A size target is an estimate, not a guaranteed maximum.
Frequently asked questions
How much smaller is WebP than JPG?
The file is usually smaller, but the result depends on the image and the quality you pick. The final size is shown next to each file — compare it with the original.
Will WebP open everywhere?
Modern browsers support it, but not all editors, messengers and print services do. If you need maximum compatibility, keep JPG.
Can I set a file size?
Yes, in the settings you can enter a target size in KB. It is an estimate: the final weight depends on the image, and the converter tells you if the target could not be reached.
Is it free, and are my photos uploaded to a server?
The converter is free and needs no account or credits. Photos are processed in your browser on your device and are not uploaded to a server. Source EXIF and GPS metadata are not copied to the new file.
