Video tools
Free video tools to compress, convert, trim, and extract audio from clips — most run right on your device, so your footage never leaves it.
- Add Subtitles to Video (Burn-In)
Add subtitles to a video permanently. Load an SRT or VTT, or let Whisper write one from the speech, then style the captions on a live preview and export an MP4 with the words on every frame.
- AI Video Subtitle Generator
A video subtitle generator built on Whisper. Feed it an MP4 and get SRT, WebVTT or a plain transcript, with cues capped at two lines of 42 characters.
- Extract Audio from Video
Extract audio from a video and keep the soundtrack on its own. AAC inside an MP4 is copied across without re-encoding, so the M4A you get back holds the original track untouched.
- Merge Videos
Merge videos into one MP4 or WebM. Seven transitions plus a plain cut sit at every join, and each clip can be trimmed before it renders.
- Mute Video
Mute a video by dropping its audio tracks while the picture is copied across without re-encoding, so a two-minute clip finishes in seconds and the frames come back identical.
- Trim Video
Trim a video down to the part worth keeping, or lift several pieces out of one recording and join them. Pull only the end handle in and nothing goes through the encoder.
- Video Compressor
Compress a video to a target you type in MB, with presets at 16 for WhatsApp, 25 for email and 10 for Discord.
- Video Converter
Video converter for MP4, MOV, MKV and WebM. Every target says up front whether it repackages the clip or re-encodes it.
- Video to GIF
Convert a video to a looping GIF at 10 to 24 fps and the width you choose, with a preview that plays before you save.
These video tools handle the quick clip jobs that usually mean installing software or uploading to a server — shrink a video to fit WhatsApp, email, or Discord; convert between MP4 and WebM; trim out just the part you need; turn a clip into a shareable GIF; pull the audio out as an M4A or WAV; or strip the soundtrack entirely. Each does one job, opens instantly, and needs no sign-up.
They run on your device using the browser's built-in, hardware-accelerated video engine, so your footage is processed locally and never uploaded — which matters for personal clips, client work, and anything confidential. Because the encoder is the same one your device uses for its own camera, compression and conversion are quick, and the tools keep working even after you go offline. Very large files and a few rare formats can be limited by your browser and device memory; each tool tells you when that's the case.
