The short version

Add JPEG, PNG or WebP frames, change their order and timing, preview the sequence, then download the WebM file or individual source frames.

Step by step

How to use Animated WebM Maker

  1. 1

    Upload images

    Drag and drop multiple JPEG, PNG or WebP images, or use the file picker. Each image becomes one frame in the animation.

  2. 2

    Arrange frames

    Use the up/down arrows to reorder frames. Remove unwanted frames with the trash icon. The frame list shows thumbnails for easy identification.

  3. 3

    Set animation speed

    Adjust the frame delay slider from 50ms (fast, 20fps) to 2000ms (slow, 0.5fps). The default 500ms (2fps) works well for most slide-show style animations.

  4. 4

    Preview the animation

    Click Play to see a live preview of your animation cycling through all frames at the set speed. Pause at any time to inspect a specific frame.

  5. 5

    Download

    Click Download WebM to record the animation as a video, or download the original frame images individually.
