How to make a photo collage on iPhone.

Apple has never shipped a collage feature in the Photos app, despite it being one of the most requested things people try to do with their camera roll. What exists instead is a set of workarounds of varying quality, plus a category of third-party apps built to fill the gap.

Here is every genuine option, what each is actually good at, and the resolution mistake that ruins more collages than bad layout ever has.

Does the iPhone have a built-in collage maker?

Not in the Photos app. The four free options are the Shortcuts app for automated grids, and Freeform, Keynote or Pages for manual layouts you export as an image.

How do you make a collage with Shortcuts?

Create a shortcut combining Select Photos (multiple enabled), Combine Images in Grid mode, and Save to Photo Album. It is free, offline, repeatable and appears in your share sheet.

The closest thing to a native collage maker on iPhone, and genuinely useful once set up.

1. Open Shortcuts and tap + to create a new shortcut.
2. Add "Select Photos" and enable Select Multiple in its options.
3. Add "Combine Images". Choose Grid as the mode, and set the spacing you want between photos.
4. Add "Save to Photo Album" so the result lands in your library.
5. Name it and run it. It appears in your share sheet, so you can start from the Photos app directly.

Good for: quick uniform grids, free, offline, no account, repeatable.
Not good for: anything with frames, text, backgrounds, uneven layouts or per-photo cropping. Combine Images arranges what you give it and nothing more.

One quirk worth knowing: the grid arrangement follows the order you selected the photos, and the output ratio is determined by the source images. If your photos are mixed orientations, the grid will be uneven — crop them to a consistent ratio first.

Can you make a collage in Freeform?

Yes. Freeform lets you drag, overlap, rotate and scale photos freely, then export the board as an image. Its limitation is output size — it exports the board, not a fixed canvas, so hitting exactly 1080 × 1350 takes trial and error.

Apple's whiteboard app is an unexpectedly capable collage tool, because it is genuinely freeform: drag photos anywhere, overlap them, rotate them, add text and shapes.

1. Create a new board in Freeform.
2. Insert your photos via the media button, then drag, scale and rotate them.
3. Add text or shapes if you want them, and set a background colour.
4. Export the board — share it as an image or PDF rather than screenshotting.

Good for: overlapping scrapbook layouts, mixing photos with text and doodles, no cost.
Not good for: controlling the exact output size. Freeform exports the board, not a fixed canvas, so getting a clean 1080 × 1350 result takes trial and error.

How do you make a collage with exact dimensions?

Use Keynote and set a custom slide size in Document Setup — the only free method that controls exact output dimensions. It is precise and genuinely tedious on a phone screen.

The most precise free option, and the most tedious.

1. Open Keynote and create a blank presentation.
2. Set the slide size. In Document Setup, choose a custom size matching your target ratio — this is the part the other free methods cannot do.
3. Place your photos on the slide. Use the mask tool to crop each one, and the alignment guides for even spacing.
4. Export as an image. Share, then Export, then Images, choosing the highest quality available.

Good for: exact canvas dimensions, precise alignment, layered elements and text.
Not good for: speed. Building a nine-photo collage this way on a phone screen is a genuinely unpleasant twenty minutes.

What should you look for in a collage app?

Six things: whether exports are watermarked, what resolution it exports at, whether an account is required, whether photos are processed on a server, whether you can set an exact output ratio, and whether it recompresses.

This is what most people end up doing, because the built-in routes each fail at something important. What separates a good app from a bad one is not the number of templates:

The watermark and resolution questions are the ones that matter most, and neither is usually answered on the App Store page. Test with one collage before you commit to a workflow.

Why does my collage look blurry on Instagram?

Usually because it was screenshotted rather than exported. A screenshot captures at screen resolution — around 1170–1290 px on a modern iPhone — of an image already compressed for display, then Instagram compresses it again.

The most common reason a collage looks worse than the photos that went into it has nothing to do with the collage tool. It is the export.

Never screenshot the canvas. A screenshot captures at your screen's resolution — roughly 1170 or 1290 pixels wide on a modern iPhone — of an image the app has already rendered and compressed for display. You then hand that to Instagram, which compresses it again. Three generations of loss for a step you could have skipped.

Instead:

• Export at 1080 px on the short edge. Not more — Instagram downscales anything larger and then re-encodes it, which is two destructive steps rather than one.
• Export as JPEG at 85–95% in sRGB. Instagram converts to JPEG regardless.
• Check the exported file, not the preview. Open it in Photos at full size before posting.

The full explanation is in why Instagram ruins your photo quality, but the short version is: every app between your camera and Instagram that re-saves your image costs you quality that cannot be recovered.

How do you make a photo collage look good?

Six rules: use an uneven grid rather than equal squares, keep spacing consistent, let the background do work, leave a margin for the 3:4 grid crop, limit the colour palette, and keep detail away from the edges.

Layout advice that holds regardless of which tool you use:

• Uneven grids beat even ones. One large photo with several small ones reads as designed; nine equal squares reads as a contact sheet.
• Pick a spacing and keep it. Inconsistent gaps are the fastest way to look amateurish. Either tight and uniform, or generous and uniform.
• Let the background do work. White is safe. A paper texture, a colour drawn from the photos, or a soft gradient all look more considered than white for the same effort.
• Leave a margin. Photos running to the very edge lose to the profile grid's 3:4 crop.
• Limit the palette. Photos with a common colour cast hold together; a mixed set fights itself.
• Keep detail away from the edges. Especially the top and bottom, which the grid crop removes first.

Which app makes collages at Instagram sizes?

You need one that lets you set the output ratio and exports at full resolution without a watermark. That combination is rarer than the App Store makes it look.

We built DUMP because none of the free methods handle the actual end-to-end job: build a layout at a fixed Instagram ratio, do it fast on a phone, and get the result into Photos without a quality tax.

It has two relevant modes. Grid gives you preset layouts with live spacing, corner radius and ratio control — the Shortcuts approach, but with the controls Shortcuts lacks. Canvas is freeform: place, scale, rotate, layer and mask photos on a page with frames, stickers, textures and text — the Freeform approach, but on a fixed canvas that exports at exactly the size you need.

Exports go straight into a new Photos album at full resolution, with alpha preserved where a layout has transparency, and no watermark on either tier. It is free, requires no account, and works with your phone in airplane mode.
