Common Use Cases
These collage needs are all handled by one tool
Whether you're building a comparison image, organizing a long screenshot, or making a grid post for social media, choosing the right layout gets it done in one pass.
Before/after comparison images
Combine a “before” and “after” image into a single comparison graphic using a horizontal or grid layout, making it easier to send to a client or publish a review, instead of switching between two separate images.
Organizing long screenshots and chat logs
Stitch multiple chat screenshots or web page screenshots into a single vertical long image, so you don't have to save or forward a bunch of scattered images.
Layout Details
Horizontal, vertical, grid, and template — what each one is best for
Free-form layouts work for any number of images; template collages use fixed slot layouts, great for comparison images or magazine-style layouts that need irregular grid shapes.
| Layout | How it's composited | Best for |
|---|---|---|
| Horizontal long image | All images are scaled to the same height and placed side by side, with each width calculated proportionally — no cropping | Combine several portrait photos into a horizontal comparison or long image |
| Vertical long image | All images are scaled to the same width and stacked top to bottom, with each height calculated proportionally — no cropping | Combine several landscape screenshots or chat logs into a vertical long image |
| Grid layout | Automatically arranged into rows based on your chosen column count, with each image center-cropped to fill a square cell (like a photo grid) — images with different ratios still line up neatly | Grid-style social media posts, quick layout previews for multiple images |
| Template collage | Arranged into preset irregular slots (like side-by-side, hero + two, or magazine five-up), each cell cover-cropped to fill; the number of images needed is fixed by the template | Before/after comparisons, hero-image emphasis, magazine-style multi-image layouts |
To keep cells neat, grid and template layouts scale images proportionally and center-crop to fill each cell (the extra part gets cropped, not stretched). If you don't want any content cropped, switch to a horizontal or vertical long image layout instead.
How to Use
4 steps to create a photo collage
No software to install — everything happens right in the browser.
-
1
Upload images
Click to select or drag your images into the page — select at least 2 (or however many your chosen template requires); up to 30 images, 20MB each.
-
2
Choose a layout
Pick a horizontal long image, vertical long image, grid layout, or template collage; specify a column count for grids, or switch between side-by-side, hero + two, and other template styles; then set spacing and background color.
-
3
Reorder your images
Drag the handle on the left of the list, or click up/down, to arrange your images in the order you want; in template mode, the first few images fill the slots in order.

Generate and download
Click to start the collage — it's generated in a few seconds. Confirm the result looks right, then download it.
Technical Notes
Two things worth knowing about local collage creation
01
Composited entirely in your browser
Using the browser's native Canvas drawing capability, your device draws each image onto a single canvas following your chosen layout, then exports the result — the whole process never touches a server, and both the originals and the final collage only exist in your device's memory.

Why a collage doesn't count as “batch processing”
Batch processing means “multiple images each processed independently, producing multiple independent results” (like batch compression producing several compressed images). A collage, on the other hand, merges multiple images into one output — it's essentially a one-time layout composition, so we don't offer a batch mode for it, though it still supports selecting multiple images at once for the collage itself.
FAQ
Common Questions About the Collage Maker
Does the collage maker support batch processing?
The essence of a collage is combining multiple images into one output — there's no “each image processed independently” semantic, so it doesn't count as a batch tool. But it does inherently support selecting up to 30 images at once for a single layout, which is where it's just as efficient as a batch tool, in its own way.
Why does the grid layout crop part of my images?
To make every image neatly fill a uniformly sized square cell (for a tidier visual result), grid mode scales each image proportionally and center-crops it — anything outside the cell gets cropped, not stretched. If you don't want any content cropped, switch to a horizontal or vertical long image layout instead — both fully preserve every image's content.
Can I reorder the images after combining them?
Yes. Every uploaded image appears in the list below — on desktop, drag the handle on the left of each row to reorder, or click the up/down buttons (more convenient on touchscreens). The list order becomes the actual left-to-right or top-to-bottom order in the final collage.
What are the background color and spacing settings for?
Spacing controls the width of the blank gap between images — set it to 0 for images that touch directly. Background color fills those gaps, as well as any unfilled cells in the last row of a grid layout. It defaults to white but can be set to any custom color.
Is the collage created on my computer or phone, or does it get uploaded to a server?
It's done entirely in your current device's browser. Using the browser's built-in Canvas drawing capability, multiple images are combined into a single result image — none of the originals are ever uploaded to a server.
What's the difference between a template collage and a grid layout?
A grid layout is evenly spaced rows and columns, with unlimited image count and an adjustable column number. A template collage is a fixed set of irregular slots (like a large image on the left with two small ones on the right) — each template needs a specific number of images, and any extras won't be included. Use a template for comparison images or magazine-style layouts, and a grid when you need any number of images arranged neatly.
Will the finished collage have a watermark?
No — the result doesn't include any watermark or mark. If you want to protect your original combined content, you can separately use the “Add Watermark” tool to apply your own.
