How to Make a Photo Collage for Instagram or Facebook

Here's the real process for turning several photos into one combined image with Photo collage maker, sized for wherever you're posting it.

Step 1 - choose 2 or more photos

Pick between 2 and 9 photos at once (JPG, PNG, WebP, GIF or BMP). They fill the grid in the order you add them - top-left first, reading order across, matching the same "pages go in list order" convention this site's PDF tools already use. Want a different order? Each photo in the list has Move earlier and Move later buttons.

Step 2 - pick a layout

Choose a preset grid - 1×2, 2×1, 2×2, 3×1, 1×3, or 3×3 - or switch to Custom for any rows-by-columns grid up to 5 per side. A live preview appears as soon as you've got at least one photo and a layout chosen, so you see the actual arrangement before running anything.

Step 3 - adjust spacing if you want gaps between photos

By default the photos sit edge to edge with no gap. A spacing slider (0-5%) adds a gap between cells if you want one, and once spacing is above zero a color picker appears for the gap color - the same color also fills any empty cell (see below).

Step 4 - pick an output size and download

The size list reuses the same platform preset table as the social media image resizer and the quote card maker, so the collage comes out already sized for wherever you're posting it - an Instagram square, a Facebook cover, whichever fits. Click the Combine button (it reads "Combine 4 photos" with four chosen) and the combined image downloads as a single JPG.

Removing or replacing a photo

Every photo in the list has its own Remove button, and taking one out updates the live preview immediately - no need to start over with a fresh selection. To replace a photo in a specific position, remove it, add the replacement through the file picker (it joins the end of the list), then move it up into place.

If a file can't be used

A file that isn't a supported image format, or one over the size limit, gets skipped with a plain message naming which photo and why - the rest of your selection still processes normally. One bad file in a batch of eight never blocks the other seven.

If you pick more photos than the layout has room for

Say you choose 5 photos but stay on a 2×2 layout (4 cells). The 5th photo gets a plain "not used in this layout" badge right in the file list - not silently dropped without a trace - and a hint suggests choosing a bigger layout or removing one. Nothing disappears without telling you.

If you pick fewer photos than the layout has room for

Choose 3 photos on a 2×2 layout, and the 4th cell gets filled with your chosen gap color rather than left blank or broken - so the output is always a complete rectangle, and you can see exactly which cell will be empty in the live preview before you download.

Switching layouts after you've already added photos

Changing the layout at any point - from 2×2 to 3×3, or to a custom grid - keeps your existing photos and just redraws them into the new arrangement, so there's no need to remove and re-add anything just to try a different grid. The over- and under-capacity handling above recalculates automatically for whichever layout is currently selected.
