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 output quality if needed.
  3. Start processing, download each generated file, or let all local data clear automatically after 15 minutes.

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.
