About these tools

Video tools use your browser's built-in video encoders and decoders. Trimming, muting and rotating copy the original video data whenever possible, so there is no quality loss; compressing and converting re-encode the video.

Encoding speed depends on your device. Short clips take seconds; long, high-resolution videos can take several minutes. Current versions of Chrome, Edge, Safari and Firefox are supported.
