MP4 to WebP Studio

Trim and compress MP4, WebM, MOV, AVI, or MKV clips into animated WebP avatars, static profile pictures, or custom WebP and GIF loops. Conversion runs locally in your browser; Bonjourn uploads a finished file only when a signed-in user saves it.

Camplifier avatar

Create a square animated WebP with a 512×512 crop and size-conscious export.

Static profile picture

Choose one frame and export a lightweight square WebP profile image.

Custom clip

Keep your preferred aspect ratio, trim the loop, add text, and choose WebP or GIF.

Get a clean loop without carrying extra file weight

  1. 1. Trim first. Keep only the motion you need to reduce encoding time and file size.
  2. 2. Match the destination. Use a square preset for avatars or custom dimensions for other sites.
  3. 3. Preview, then export. Compare the loop and size before downloading or saving it.

Animated WebP usually preserves smooth color and transparency in a smaller file. GIF remains useful when the destination does not support animated WebP.

Sign in before converting to enable private Gallery autosave. Publishing to the public GIF Library remains a separate, tagged opt-in that may require review.
