This page opens on Upload a video, with Deep as the first voice to try. Pick a clip from your phone or computer; a few seconds later its sound plays back changed. Click through the other voices on the same clip, and when one fits, press Make the video with this voice. The finished video appears in a player on the page, so you can watch it with its new sound before you save it.
How the new file is built
Think of a video as a box holding several streams side by side: frames, sound, sometimes subtitles. This tool opens the box, takes the frames out exactly as they were stored and puts them in a new box of the same kind, next to a freshly encoded sound stream carrying the changed voice. Because no frame is decoded and redrawn, there is no generation loss, and a 1080p phone clip keeps every detail. A stereo video stays stereo (the changed voice sits in the middle, on both sides); subtitles, extra sound tracks and metadata such as where the clip was filmed are left out.
Picking a clip that works
Choose the part of the video where the voice is clear and nothing else is loud: wind, traffic and background music are changed along with the voice and can turn into a rumble or a warble. Short clips are quicker to try voices on, and the tool takes up to 5 minutes of sound, so trim longer recordings to the scene you need first.
Sending the result to a group chat or a Discord server? The voice changer for Discord page covers live use too. Want the original soundtrack on its own, untouched? Extract audio saves it as a file.
