About this tool
Add Music to Photos builds a slideshow video from your pictures and a song in your browser: FFmpeg fits each photo into the frame, fades it in and out, cycles the photos for the length of the music and muxes it all into an MP4 ready for YouTube, Instagram or TikTok. Nothing is uploaded.

Key features of this tool
Fades and cycling
Photos fade in and out and repeat in order until the music ends, each on screen for 3 to 8 seconds depending on how many you add.
Music sets the length
The video is exactly as long as the audio track, encoded to AAC with the pictures in H.264.

Frequently asked questions
How long is each photo shown?
The song length divided by the number of photos, clamped between 3 and 8 seconds; with few photos and a long song they cycle.
Can I use one photo only?
Yes: it stays on screen for the whole track, handy for turning audio into a video for platforms that need one.
Why is the first use slow?
FFmpeg (about 30 MB) is downloaded the first time and cached; after that it starts in a second or two. Encoding itself runs on one CPU core, so long videos take a while.
Are my files or data uploaded?
No. The tool is plain JavaScript that runs in your browser; the files or data you provide here are never uploaded to our servers.
