How many photos can I use?
As many as your device handles comfortably; a few dozen is typical. The song decides how many are shown: a one-minute song at Every 2 beats and 120 BPM shows 60 photos, and fewer photos simply repeat.

A slideshow maker with music that changes on the beat
Add a song and your photos. Each picture arrives exactly on a beat, with a slow zoom to keep it moving, and you export a video ready to share or play on a TV.
To make a slideshow with music, add your song and your photos together: the tool finds the song’s beats and changes to the next photo exactly on one, every two beats to start with. Press Export video and you have a photo video in which the pictures move with the music instead of drifting across it at a fixed pace.
That timing is what separates a slideshow people watch from one they sit through. A photo that appears on a downbeat feels intentional; the same photo arriving half a beat late feels like a mistake, even if nobody can say why. Slow zoom on photos adds a gentle push in or out while each picture is on screen, and Transitions decides how one photo gives way to the next.
Your photos and music stay on your device; nothing is uploaded and there is no watermark. Need the tempo first? The BPM finder reads it from the song, and tap tempo works when the music is playing elsewhere. For video clips rather than photos, use beat sync.
How to make a photo slideshow with music
Add the song and the photos
Drop them onto Drop a song and your photos, or press Choose files. JPEG, PNG, WebP and iPhone HEIC photos work; Add photos brings in more. Then press Make the beat video.
Set the pace
The Cut style starts at Every 2 beats. Choose Every bar for a calmer show or Every beat for a quick one; Follow the energy speeds up in the chorus.
Order and frame the photos
Select a photo and press Move earlier or Move later to reorder it, or Remove it. Under More options, Fit chooses Fill the frame or Whole picture, and Slow zoom on photos turns the movement on or off.
Pick the shape and length
Set the Shape: 9:16 for phones, 1:1 for feeds, 16:9 for a TV or YouTube. Choose how much of the song to use under Song part (15 s, 30 s, 1 min or All) and where it Starts at.
Export video
Press Export video, then Download video. On a phone, Share saves it to your photos.
How long each photo stays on screen
The length of each photo comes from the song, not from a seconds setting. With Every 2 beats, a song at 120 BPM shows each photo for one second; at 90 BPM, for 1.33 seconds. That is the trick: the rhythm you hear decides the rhythm you see.
| Tempo | **Every beat** | **Every 2 beats** | **Every bar** (4 beats) |
|---|---|---|---|
| 80 BPM | 0.75 s | 1.5 s | 3 s |
| 100 BPM | 0.6 s | 1.2 s | 2.4 s |
| 120 BPM | 0.5 s | 1 s | 2 s |
| 140 BPM | 0.43 s | 0.86 s | 1.7 s |
Under a second per photo suits a lively reel of many pictures. For a birthday, a wedding or a memorial, where people want time to look at each face, Every bar with a slower song is kinder. If you have fewer photos than the song needs, they repeat in order; add more, or shorten the Song part.
Making photos feel alive
Slow zoom
Slow zoom on photos moves gently in or out across each photo while it is on screen, so a still picture has some life. It is turned off automatically if your device asks for reduced motion.
Transitions on the beat
- Cut is crisp and modern; it relies entirely on the beat for its punch.
- Fade softens the change, good for gentle songs.
- Flash and Zoom add energy on strong beats.
- Slide pushes the next photo in from the side.
- Auto chooses for each change: soft fades in quiet passages, a flash where a drop hits.
Portrait and landscape photos together
Phone pictures are often a mix of tall and wide. Fill the frame crops each one to the shape you chose, which looks bold but can cut off heads in a group shot; Whole picture shows every photo complete with plain bars beside it. Try both on the preview.
Music, copyright and ending well
Use any song file you have: MP3, M4A, WAV, or the soundtrack of a video. If you plan to post the slideshow publicly, make sure you have the right to use the song: a track you bought is usually for listening, not for publishing. Royalty-free music libraries and the music offered inside some social apps are the safer route for public posts.
Start the Song part where the music gets going, so the first photo lands on a real beat, and turn on Fade out the music so the show ends gently instead of mid-phrase. If the music needs to go onto a finished video rather than photos, add audio to a video does that.
Slideshow with music questions
Can I mix photos and video clips?
Yes. Clips and photos can be added together, and each takes its turn on the beat.
Can I choose how long each photo shows?
Indirectly, through the song and the Cut style: every beat, every two beats or every bar. That keeps every change on the music.
Will the slideshow play on a TV?
Choose the 16:9 Shape and export an MP4; most TVs and streaming sticks play it from a USB stick or a phone cast.
Do iPhone HEIC photos work?
Yes. Photos your browser can’t show directly are converted on your device first.
Is there a watermark?
No watermark and no account. The photos and the song stay on your device.
