Make a photo collage online
Select several photos at once or reopen the picker to add more. Choose a grid and create a downloadable collage directly in your browser. For best results, crop images first with the Image Crop Tool.
How to create a collage
- Select two to nine images. You can add them in multiple rounds.
- Remove any unwanted photo using the × button.
- Choose two or three columns and set the spacing.
- Create the collage, then download the JPG.
Frequently asked questions
Can I add photos one by one?
Yes. Reopen the picker and each new selection is added to the existing photos until the nine-photo limit.
Can I create a collage on mobile?
Yes. Select photos from your phone and download the finished collage in your browser.
Are my photos uploaded?
No. The collage is created locally in your browser.
Build a collage that looks balanced instead of crowded
A good collage is easier to read when the photos share a clear visual hierarchy. Choose one or two important images to carry attention, then use the remaining images as supporting context rather than forcing every photo to compete equally.
Prepare images before arranging them
Crop distracting edges and rotate photos correctly before placing them. Images with very different aspect ratios can create awkward empty areas, so a little preparation usually produces a cleaner layout than stretching each photo to fit.
Keep important subjects away from edges
Faces, text and key objects should have breathing room. If the collage will be posted on social media, remember that some platforms crop previews differently on phones and desktop screens.
Export at the right size
For sharing online, you usually do not need the full resolution of every source photo. For printing, use higher-resolution originals and inspect the final dimensions before export so the collage does not become blurry when enlarged.
How the collage grid is calculated
The collage is rendered on an HTML Canvas rather than by taking a screenshot of the page. The selected output width, column count and gap value are used to calculate a square cell size. The number of rows is derived from the photo count, so the final canvas height expands automatically when another row is required. This keeps spacing consistent instead of relying on manually positioned image elements.
Cover-style cropping inside each square cell
Every source photo keeps its original aspect ratio. To fill a square cell, the renderer chooses the larger of the horizontal and vertical scale factors. That is the same basic geometry as a CSS cover fit: the image completely fills the cell, while any excess width or height extends beyond the square. Canvas clipping then hides that overflow and the image is centred, which is why subjects near an edge may be cropped even though the source itself is not stretched.
Spacing, resolution and JPEG export
The gap value is included around the outside of the grid and between cells. After all photos are drawn, the canvas is exported as a JPEG at a quality value of 0.92. The background is explicitly filled white, so the downloaded collage is a conventional opaque JPG. Output width controls the final pixel resolution: increasing it can improve detail for larger displays or prints, but it also increases the number of pixels the browser must allocate and encode.
Why repeated re-encoding can reduce quality
Most phone photos already use lossy JPEG compression. Drawing those photos to a canvas resamples their pixels, and exporting the finished canvas as another JPEG performs a new compression pass. Repeating that cycle multiple times can gradually soften fine texture and text. For the cleanest result, build the collage from the highest-quality originals you have, choose the final output width once, and avoid repeatedly editing an already exported collage.
