Reverse Video
Plays a clip backwards, decoding one keyframe interval at a time so memory stays bounded, with the audio reversed sample by sample or muted. Refuses, with the numbers, when a keyframe interval would not fit the memory cap.
Drop a video to run backwards
Decodes a keyframe interval at a time to flip the frames, and reverses the audio sample by sample. A file whose interval would not fit in memory is refused, with the numbers.
Everything happens in this tab. The video is never uploaded.

Video Editor
Assembles clips into a YouTube or Shorts upload in the browser: trim, order, transitions, a music bed and subtitles. Same-batch AI clips with hard cuts export losslessly without re-encoding.
Video Trimmer
Cuts a clip between two timestamps, copying streams without re-encoding when the cut is on a keyframe.
Video Converter
Reads MP4, MOV, WebM and MKV and writes MP4 (H.264 + AAC) or WebM (VP9 + Opus) with quality and resolution settings. When only the wrapper changes — MOV to MP4, MKV to WebM — the streams are copied untouched.
Video Compressor
Re-encodes to a target file size or a quality preset, stepping the resolution down when the bitrate would starve it, and shows the projected size before it starts and the actual size after.

These accept what this tool produces, so the result can go straight in.
Speed Changer
Speeds up or slows down a video from 0.25× to 4×. The picture is retimed frame-exact; the audio keeps its pitch through WSOLA time-stretching, or can follow the speed tape-style, or be muted.
Video to GIF
Turns a clip into an animated GIF or WebP with frame rate, size and palette controls.
Video Trimmer
Cuts a clip between two timestamps, copying streams without re-encoding when the cut is on a keyframe.
Audio Converter
Converts between MP3, WAV, FLAC, AAC, OGG and Opus with bitrate and sample-rate settings.
Extract Audio from Video
Pulls the audio track out of a video as MP3, WAV, M4A or FLAC, or copies it without re-encoding.
Audio Trimmer
Cuts a section out of an audio file on the waveform, with fade in and fade out.
