</iframe>WWebP is an excellent format for video thumbnails and preview images — it offers better compression than JPEG while supporting transparency. Converting an MP4 video to a WebP image extracts a single frame and encodes it as a high-quality WebP. This is useful for generating poster images, Open Graph previews, and animated thumbnail stills.
The tool uses the browser's built-in HTML5 video decoder to load the MP4, seek to a representative frame (10% into the video, capped at 1 second), and capture it to a canvas. The canvas is then encoded as WebP at 92% quality. This approach requires no external libraries — everything runs natively in the browser.
Because the video is decoded locally using the browser's media engine, your file never leaves your device. There is no upload, no server-side processing, and no privacy risk. The tool supports MP4, WebM, MOV, and M4V files up to 50 MB. Note that videos using codecs the browser cannot decode (e.g., some H.265/HEVC variants) will produce an error.

The tool seeks to 10% of the video duration (capped at 1 second) to skip potential black intro frames. This gives a representative frame from the beginning of the video.
Currently one frame is extracted per video file. For multiple frames, upload the same video multiple times or use a dedicated video editing tool.
MP4 (H.264), WebM (VP8/VP9), MOV, and M4V are supported. The browser must be able to decode the video codec — most modern browsers support H.264 and VP8/VP9.
