How to convert WEBM to WEBP

  1. Drop your .webm files above, or click Upload Files. You can add many files at once.
  2. WEBP is already selected as the output. Open the settings (gear icon) to fine-tune the result.

Frequently asked questions

Is it safe to convert WEBM to WEBP here?

Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.

Is there a file size limit?

There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.

Can I convert several WEBM files at once?

Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
