Pick your video and your music together and get the video back with the music under it, original sound replaced, or kept with the music mixed underneath. No watermark, no account, free.
Every converter here is free, full size, no account. Photos convert in your browser and never leave it, except camera RAW files and SVG tracing. Those, like video, audio and e-books, need our server, and we delete them right after.
Two modes, one honest difference. Replace throws the original sound away: right for slideshows, drone shots and gameplay where the original audio is wind or fan noise. Mix keeps the original and lays the music under it at 30% volume: right for talking videos where the voice must stay understandable. If the music itself has vocals, pulling those out first with StemGrab's instrumental maker keeps two voices from competing under your narration.
Either way the video keeps its full length: shorter music runs out into silence, longer music is cut at the video's end. And the picture is copied through untouched: no re-encode, no quality loss, no watermark.
Just need the sound gone, without new music? That's remove the audio. Music too loud or too quiet afterwards? Change the volume.
Used Clideo add music to video, Kapwing add music to video or the Videobolt add audio to video tool before? This one works the same way from your browser, without an account or a watermark; the only limit is 1200 MB and 20 minutes per file on the free tier. It suits a phone clip as well as a finished edit: same two files, same steps.
How to add music to video online, in short: pick both files, choose replace or mix, and download. No timeline editor, no software, no sign-up, so you can add music to video free online in under a minute. Adding audio to video works exactly the same whether the second file is a song, a voiceover or a sound effect: MP3, WAV, FLAC and M4A all go in, so you can add MP3 to video, add sound to video online, or add song to video clips for a birthday message, all from one page.
In mix mode the music sits as audio over video at 30% volume. That makes it a simple video audio mixer and a way to combine music with video: add background music to video while the voices stay at full level. You can also put music over video without silencing the original recording. Replace mode does what it says: it will replace audio in video outright, which is also the way to replace audio in video online when the original sound is only wind or fan noise. Audio and video stay in sync either way, since the picture is never re-encoded; as an audio adder to video it only rebuilds the sound track.
To put music on video online, pick both files together; mix mode lets you overlay audio on video without silencing the original, which is the way to insert music under dialogue. The music adding step is two files and one click. As a music adder to video it treats a song and a voiceover the same, and it works as a simple video and audio mixer. To add audio file to video, pick the MP3, WAV, FLAC or M4A as the second file. It suits a phone clip too: add music to clip footage from a trip with the same steps.
Select both files in one go: the video and the music (MP3, WAV, FLAC or M4A), holding Ctrl (Cmd on a Mac) in the file dialog. The tool works out which is which by itself.
Up to 1200 MB and 20 minutes per file, and the whole thing runs on our own server: uploaded, combined, sent back, deleted.
Want to add audio to video YouTube will accept? Nothing changes: download the finished MP4 and upload it as you would any other export.
Yes: this page never adds watermarks, needs no account and has no daily cap, up to 1200 MB per file, every time.
No. In both modes the picture is copied through bit-for-bit and only the sound track is rebuilt, so picture quality and video quality stay exactly as they were.
The video always keeps its full length: shorter music runs out into silence, longer music is cut when the video ends.
Mix keeps the original sound at full volume and lays the music under it at 30%: a true music overlay, and the setting to use when people talk in the clip. Replace drops the original sound and the new track takes its place. If "add background" to you means music, that is Mix; if you mean a background image or a virtual background behind the person in frame, that is a different job, which VideoBGNinja's virtual background tool does.
MP3, WAV, FLAC and M4A, up to 1200 MB and 20 min.
Combined on our own server, sent straight back, and both uploads are deleted the moment the job finishes.
Select the video and the music file together using the box above, pick Replace or Mix, and download the result. Nothing to install and no account, which is all there is to how to put music over a video, or how to add audio to video in general.
Yes: any audio file works as the second file (MP3, WAV, FLAC or M4A), so a voiceover, a voice memo or a sound effect goes in the same way as a song; put music or a voice on, the steps do not change.
Open this page in your phone's browser, select the video and the audio file together from your gallery and files, and download the result. That is how to add music to a video on Android with just the phone (how to add music to video on Android needs no app), and on an iPhone in Safari it works the same.
This page only adds music. Looking for a music remover from video that strips the soundtrack completely instead? Remove the audio does that: no new music added, just silence.
If you mean editing the file before you upload it: pick the video and the music file together above, choose replace or mix, and download the result. That's how to add music to your YouTube video without opening YouTube's own editor. Once it's already live on YouTube, this tool can't reach it; you would need YouTube Studio's own Audio Library instead.
Only one video at a time: this tool mixes in music, it does not join clips. To add video together into a single file, use merge videos first, then bring the combined result back here to add music underneath it.
No: this page only adds a soundtrack, it doesn't pull one out. To extract music from video, our sister site's video to MP3 tool does that instead. Drop the video in there and get the audio back as its own file.
No: nothing on this site generates video or music from a prompt; every tool here works on a file you already have. If "ai music videos" means putting a real track under a real clip you filmed, that's exactly what the tool above does: just without any AI involved, your video and your music, mixed or swapped.
No, there is no text tool here: this page handles audio only. ScribeGrab's subtitle burner is the tool to add text to video, or add text to a video as captions: it transcribes the speech and burns the words into the picture, so they are permanent and show up on TikTok or WhatsApp without a separate file. That is the way to add text in video permanently, unlike a .srt file a viewer can switch off.
No. This tool only lays audio under or over the original sound; there is no add image video mode and no way to add image to video frames, and nothing on this site places a logo, a title card or a photo into a moving video, or turns a single picture into one. For an "add picture to a video" job, as an overlay, a slide or an end card, or to add photo to video content in bulk, use a video editor first; the soundtrack comes after.
No, this needs a video to start with; a JPG or PNG never becomes one here. If you want to add music to photo content for something like an Instagram post, a slideshow app, or Instagram's own Reels editor, which turns a photo into a short clip automatically, has to make the video first; bring that video back here if you want a different soundtrack.
