Silence Cutter
Finds quiet stretches in a recording and removes them, with a threshold and padding setting.
Drop a recording to cut the silence out of
Podcasts, lectures, voice memos. Quiet stretches are found by level, shortened to a stated amount of breathing room, and the result comes out as WAV. Audio files only — the video version of this is a re-encode, and the refusal explains why.
Everything happens in this tab. The recording is never uploaded.

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.
Loudness Normaliser
Measures integrated loudness and true peak, then normalises to a target LUFS such as -14 or -16.
Noise Remover
Removes hiss, hum and room noise with spectral gating: a noise profile from a marked region or the quietest tenth of the recording, subtracted per frequency band with a stated floor. Reads audio files and the audio track of MP4/WebM; writes WAV, M4A or Opus.
Screen Recorder
Records a tab, window or screen with optional microphone and system audio, and saves the WebM or MP4 locally.

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.
