About Media Studio
Media Studio brings together 25 video tools and 30 audio tools for the small edits that do not justify installing an editor. Cut the start and end off a clip with the Video Trimmer, shrink a phone recording for a chat app with the Video Compressor, or turn a funny moment into a loop with Video to GIF. On the audio side you can trim a song against its waveform with the Audio Trimmer, make a 30-second Ringtone, or check a headset before a call with the Microphone Tester.
Decoding and encoding happen in a background worker in your browser, using the WebCodecs support built into modern browsers. Your clips stay on your device. Recorders for the screen, webcam and voice save each recording as a file on your device. For uncommon formats such as WMV, FLV or AMR, some tools offer an optional ffmpeg fallback of about 30 MB that loads from jsDelivr only when you tick it. Long or high-resolution videos need memory, so a laptop or desktop handles them better than an older phone.
