How do I convert M4V to WEBM with LetsConvert?

Upload your M4V file, choose WEBM as the output format (defaulting to VP9 video and Opus audio), adjust settings like resolution, bitrate, or FPS if needed, then click Convert. Download the resulting WEBM file once the conversion finishes. Batch upload multiple M4V files to process them simultaneously.

Why should I convert M4V to WEBM?

M4V is Apple's variant of MP4, typically using H.264/HEVC video and AAC audio. WEBM uses VP9/VP8 video and Opus/Vorbis audio, which is natively supported in all modern browsers without plugins. Converting M4V to WEBM gives you smaller file sizes with better compression for web delivery, and WEBM also supports an alpha channel (transparency) for video overlays, which M4V does not.

Does the conversion preserve quality and metadata?

Our converter re-encodes the video from H.264 to VP9, so it's not a lossless remux. The visual quality is preserved at a given bitrate, but you can choose a higher quality preset or constant quality (CRF) setting to avoid noticeable generation loss. Audio is converted from AAC to Opus with the same channel layout and sample rate. Resolution and frame rate are kept unchanged, but container metadata like cover art and chapter markers are not carried over to WEBM. If your M4V contains an alpha channel, we preserve it when encoding to VP9.
