How do I convert or compress images?

WebP Local runs entirely in your browser. It uses your device's image-processing capabilities without uploading, storing, transferring, or viewing your images; selected images and results are cleared automatically after 15 minutes.

  1. Choose images or drag them into the upload area; up to 5 can be processed at once.
  2. Choose To WebP or Compress, then adjust visual fidelity if needed.
  3. Start processing; the tool smart-matches a smaller high-fidelity result before each file is ready to download.

What is WebP Local?

WebP Local is a free, no-sign-up image conversion and compression tool that runs on your device. It is not a cloud upload service: every file is processed in the current browser.

Image conversion
Convert PNG, JPG/JPEG, GIF, BMP, WebP, and AVIF to WebP; animated GIFs retain frames, timing, and loop data.
Image compression
Compress JPG/JPEG, PNG, and WebP while retaining the original format and pixel dimensions.
Privacy and cleanup
Files are never uploaded to a server; selected images, previews, and results clear from local browser memory after 15 minutes.
