Combine several photos into one image, in a grid, row or column.
Built in your browser — no photo is uploaded.
How do you combine photos without stretching them?
Crop rather than squash. Scale each photo until its shorter side fills the cell, then trim the overflow equally from both sides — the same rule as CSS object-fit: cover. Stretching a portrait photo into a square makes faces look wide, which most people notice without knowing why.
Understanding your result
The single decision that makes a collage look right or wrong is what to do when photos have different shapes, and there are only two honest options: squash them to fit, or crop them to fit. Squashing is what makes amateur collages look subtly wrong — a portrait photo stretched into a square makes faces look wide, and most people notice the effect without identifying the cause. Cropping preserves the proportions and cuts away the edges instead, which is why it is what this tool does and what every well-designed layout on the web does through the same CSS rule. The practical consequence is worth planning for: because the crop is taken from the centre, a photo with the subject off to one side may lose them. If that happens, crop the photo yourself first so the subject is roughly centred, then bring it back here. Spacing is the other lever that matters more than it looks — a few pixels of background between cells reads as deliberate design, whereas photos butted directly against each other tend to blur into one confusing image, particularly when adjacent shots have similar colours.
Formula and method
The auto layout uses the ceiling of the square root of the image count, which gives the squarest grid that holds them all — five photos become three columns by two rows. Each photo is scaled so the shorter side fills its cell and the overflow is trimmed equally from both sides, the same behaviour as the CSS object-fit: cover rule.
Assumptions and limitations
Every cell is the same size — freeform layouts with one large photo and several small ones are not supported. Photos are centre-cropped to fill their cell, so anything important near an edge can be cut off, and there is no way to reposition the crop. The last row is left-aligned rather than centred when the image count does not fill the grid. Captions, borders per photo and text overlays are not available. Up to 24 images at once.
Worked example
Six holiday photos at 400 px each with 12 px spacing produce a 1,248 × 836 collage in a three-by-two grid, ready to post.
How to use this tool
- Choose two or more images at once.
- Pick the layout and how large each photo should be.
- Adjust the spacing, background colour and corner rounding.
- Make the collage and download it.
Common mistakes to avoid
- Using photos where the subject is near an edge, which the centre crop cuts off.
- Setting spacing to zero, so adjacent photos merge into one confusing image.
- Choosing 800 px cells for 24 photos and producing an enormous file.
- Picking JPG with a transparent background expectation — JPG has no transparency.
About the Photo Collage Maker
Put several photos into one image. Choose a grid, a single row or a stacked column, set the spacing, background colour and corner rounding, and download the result. Each photo is centre-cropped to fill its cell without being stretched.
Who should use this tool
Anyone who needs several pictures in one file — for a listing, a message, a social post or a before-and-after.
Benefits
- Photos are cropped to fill, never squashed, so faces keep their proportions.
- Grid, row and column layouts, or a fixed column count you choose.
- Spacing, background colour and rounded corners are all adjustable.
- Runs entirely in your browser — no photo is ever uploaded.
Practical use cases
- Combining product photos into one image for a marketplace listing.
- Putting a before-and-after pair side by side.
- Making a photo grid for a social post from one upload.
- Assembling screenshots into a single shareable image.
Frequently asked questions
Are my photos uploaded?
No. The collage is drawn on a canvas inside this browser tab and the images never leave your device, which matters for personal photographs in a way it does not for most files.
Will my photos be stretched?
No. Each one is scaled until it fills its cell and the overflow is trimmed from both sides equally, so proportions are always preserved and faces never look wide.
Can I choose which part gets cropped?
Not here — the crop is always taken from the centre. If the subject sits near an edge, crop that photo first with the image cropper, then add it to the collage.
How many photos can I combine?
Between 2 and 24. Beyond that the individual photos become too small to be worth showing and the file grows unhelpfully large.
Can I have a transparent background?
Choose PNG or WebP as the output format and set the spacing to zero, since JPG cannot store transparency at all. The background colour control fills any gaps.
