Online Video to WebM Converter

Convert any video file to WebM format online for free. WebM is an open, royalty-free media format designed for the web, using VP9 video and Opus audio codecs. It offers excellent compression efficiency and is natively supported by all modern browsers including Chrome, Firefox, Edge, and Opera.

Upload your video in any format (MP4, AVI, MOV, MKV, FLV, WMV, 3GP, and more) and convert it to a web-optimized WebM file. Adjust the quality slider to balance file size and visual quality - lower CRF values produce higher quality at the cost of larger files.

WebM is ideal for embedding videos on websites, sharing on platforms that support it, or reducing file sizes while maintaining good visual quality. For converting to MP4 instead, use our Video to MP4 converter.
