Free video tools for MP4 conversion, compression, trimming, GIF creation and audio extraction.
VIDEO TOOL GUIDE
Video work is more demanding than document or image processing because the browser must decode and often re-encode many frames plus an audio track. Choose the operation first, then check the output container, video codec, audio handling and expected processing time.
Trim a clip when only a time range is needed, combine clips when several sources should play in sequence, and rotate or reverse when the frames themselves must change. Compression and format conversion normally re-encode the video. Creating a GIF removes ordinary audio and can produce a much larger file than an equivalent short MP4, so it is best for brief looping animation.

.mp4 · .mov · .m4v · .webm · .avi · .mkvRotate and mirror videos in the browser while preserving available audio.
.mp4 · .mov · .m4v · .webm · .avi · .mkvCreate truly reversed video files, including reversed audio when a track is present.
.mp4 · .mov · .m4v · .webm · .avi · .mkvA filename such as MP4 or MOV describes a container, not necessarily the codecs inside it. Two files with the same extension can therefore behave differently. Large, high-resolution or long videos require more memory and processing time; keep the page open, avoid locking a phone during export and preview both picture and sound before deleting the source.
The browser must process a sequence of frames and often an audio stream, then encode and package them into a new downloadable file.
Most MP4 conversion and transform tools preserve an available audio track, but GIF output is silent. Check the individual tool’s notes before processing.
MP4 is a container. The files may use different video or audio codecs, profiles, frame rates or embedded metadata.
