About this tool

Convert one or more JPG images to WebP right in your browser: WebP is lighter than JPG and PNG for the web. Adjust the quality, pick a background color if needed, then download the files one by one or as a ZIP.

When to use it

Compatibility

Some websites, apps or printers only accept WebP.

Many images at once

Convert a whole folder of photos or screenshots in one go.

Web and sharing

Pick the format that fits the use: WebP is lighter than JPG and PNG for the web.

How to use

  1. Choose, paste or drop your JPG images.
  2. Check that the output format is WebP and adjust the quality if needed.
  3. Click “Convert”.
  4. Download the images one by one or all together as a ZIP.

How it works

The image is decoded and re-encoded in the new format by your browser.

Everything happens on your device: your images are never uploaded to a server.

Tips for best results

  • The transparency of the original image is kept.
  • A quality of 80 to 90% is a good balance between size and sharpness.
  • To reduce the size further, continue with “Compress an image”.
  • Metadata (GPS location, camera) is not copied into the converted image.

Common problems and fixes

The background turned black or white

The original image was transparent and the chosen format has no transparency. Pick a background color, or a format that keeps it (PNG, WebP).

The converted image is heavier

That is normal when switching to a lossless format such as PNG. For a light file, choose JPG or WebP.

A file will not convert

It may be damaged or in a format your browser cannot read. Open it and save it again, or try another browser.
