Speed Tools

Speed up or slow down your media files. Browse for your file type below.

SPEED_TOOLS is a file format commonly used for storing and sharing data.

They change playback speed — speed a clip up for a time-lapse effect, or slow it down for slow motion — without re-recording anything.

The audio is stretched with the video so it stays in sync. Large speed changes shift pitch, so you can also mute the track instead.

Every video and audio format on this site, including MP4, MOV, MKV, WebM, AVI, MP3 and WAV.

Speeding a file up makes it shorter and smaller; slowing it down makes it longer and larger. The bitrate itself is unchanged.
