The fastest way: using the Photos app
Your iPhone's built-in Photos app can turn a group of pictures into a slideshow in under a minute. Open Photos, tap the album or moment that holds the images you want, then tap Select in the upper right. Choose each photo you want included — the order they appear in the album is the order they'll play. Once you've selected them all, tap Add To at the bottom, then choose Create Memory or scroll down to find Slideshow if that option appears.
If you don't see a Slideshow option in the menu, tap the three dots at the bottom right of the screen instead. A menu will open with more choices. Look for Slideshow there. The Photos app will play your images in sequence with a default transition and background music. You can watch it when ready, but you cannot save it — it plays once and then stops.
This method works best when you want to preview images quickly or show them to someone in the moment. It requires no editing, no learning curve, and no extra steps. The tradeoff is that you have almost no control over timing, transitions, or music.
Key Takeaways
- The Photos app creates when ready slideshows with one tap, but they play once and cannot be saved or shared.
- iMovie lets you build slideshows you can save, edit, and share — it takes five to ten minutes and gives you control over music, timing, and transitions.
- Arrange your photos in the order you want them before you start, because changing the sequence mid-project means deleting and re-adding them.
- iMovie slideshows export as video files, so they work on any device and can be sent through email, text, or social media.
Creating a saved slideshow with iMovie
If you want a slideshow you can save, edit later, or share with others, iMovie is the better choice. Open iMovie and tap the + icon at the bottom, then select Movie. You'll see your photo library. Tap each photo you want in the order you want it — iMovie adds them to your project in the sequence you select. Once you've chosen all your photos, tap Create Movie at the bottom.
iMovie will open your project with all the photos already placed on a timeline. Each photo appears for about three seconds by default. You can tap any photo to adjust how long it stays on screen — look for the duration number at the top of the screen and change it to anything from one second to ten seconds. Tap outside the photo when you're done to save that change.
The photos will have a default transition between them (usually a fade or dissolve). You can change this by tapping the transition icon between two photos — it looks like a small diamond shape. A menu will show you other transition options like Push, Wipe, or Dissolve. Pick the one you want and tap it. Repeat this for every transition in your slideshow, or leave them all the same for a cleaner look.
Adding music and adjusting the pace
A slideshow without music feels flat. Tap the + icon at the bottom of the iMovie screen, then select Audio. You'll see three tabs: Music, Sound Effects, and Recordings. The Music tab shows songs from your iPhone's library and Apple Music. Choose one and tap it — iMovie will add it to your timeline at the bottom. The music will play under your entire slideshow.
If the music is longer than your slideshow, iMovie will loop it (play it again from the start). If your slideshow is longer than the song, the music will stop and your photos will play in silence. To fix this, you can shorten your slideshow by reducing how long each photo appears on screen, or you can add a second song. To add another song, tap the + icon again, select Audio, and choose a second track. iMovie will place it right after the first one ends.
You can also tap the music track itself to adjust its volume or fade it in and out. Tap the volume icon (it looks like a speaker) to lower the music so it doesn't overpower any narration or sound effects you might add later.
Saving and sharing your slideshow
Once your slideshow looks the way you want it, tap Done in the upper left corner. iMovie will ask you to name your project — type something you'll recognize later. Your slideshow is now saved in iMovie and can be edited anytime by opening iMovie and tapping Projects.
To share your slideshow, open the project and tap the Share button (it looks like an arrow pointing out of a box). You'll see options to save it to your Photos app, send it via Mail, Messages, or AirDrop, or upload it to social media. If you choose Save Video, iMovie will export your slideshow as an MP4 file and add it to your Photos library. From there, you can send it anywhere — email, text message, or cloud storage.
The export takes a few minutes depending on how many photos you have and how long your slideshow is. iMovie will show a progress bar. Don't close the app until it finishes, or the export will fail and you'll have to start over.
Fixing common problems during editing
If you added photos in the wrong order, tap and hold any photo on the timeline, then drag it to a new position. Release it when it's where you want it. If you want to remove a photo entirely, tap it once to select it, then press the Delete key on your keyboard or tap the trash icon if one appears.
If the music doesn't match the mood of your photos, tap the music track on the timeline and tap the trash icon to delete it. Then add a different song using the + icon. If your slideshow is too fast or too slow, adjust the duration of each photo individually — tap the photo, change the number at the top, and tap outside to save.
If iMovie crashes or closes unexpectedly, your project is still saved. Open iMovie again and tap Projects to find it. You won't lose any work unless you manually delete the project.
When to use each method
Use the Photos app slideshow when you want to show images to someone right now without any setup. It's perfect for browsing vacation photos with family or reviewing a series of screenshots. It takes seconds and requires no thought.
Use iMovie when you want a finished product you can keep, edit, or send to others. It's the choice for birthday slideshows, memorial videos, real estate listings, or anything you might want to tweak later or share beyond your when ready circle. It takes longer but gives you control and a file you own.
If you need more advanced features — like text overlays, multiple audio tracks, or precise color correction — you'll eventually outgrow iMovie. But for a first slideshow on iPhone, iMovie covers everything most people need.
Frequently Asked Questions
Can I add text or titles to my slideshow in iMovie?
Yes. Tap the + icon at the bottom of your iMovie project and select Text. Choose a text style, then type what you want. iMovie will place the text on the timeline. You can tap it to adjust how long it appears, change the font, or move it to a different spot in your slideshow.
What happens if I don't have enough photos for the music length?
iMovie will play your photos and then stop when they run out, even if the music is still playing. To fix this, either add more photos, shorten the music by removing it and choosing a shorter song, or increase how long each photo appears on screen.
Can I use photos from my cloud storage or Google Photos in iMovie?
iMovie only sees photos in your iPhone's Photos app. If your photos are only in cloud storage, read them to your iPhone first. Open the cloud service's app, find the photos, and save them to your Photos library. Then open iMovie and they'll be available.
How big is the video file when I export my slideshow?
File size depends on how many photos you have and how long your slideshow is. A typical slideshow with 20 photos and music usually creates a file between 50 and 200 megabytes. iMovie will show you the file size before you export, so you'll know if it's too large to email or text.
Can I edit my slideshow after I save it?
Yes, if you saved it as an iMovie project. Open iMovie, tap Projects, find your slideshow, and tap it to edit. If you exported it as a video file to your Photos app, you cannot edit it in iMovie — you would have to create a new slideshow from scratch or use a different app.
