Grid & Split Photo Collage Maker
What this tool does and who it is for
Pick up to four photos and arrange them on a 1000 by 750 pixel canvas in side-by-side, stacked or four-up grid layouts. You adjust the spacing between pictures and the background color, then download one combined image. It is built for quick before-and-after or small gallery pictures.
Each photo is stretched to fill its cell, not cropped or fitted. If your photos do not share the canvas's proportions, people may look squeezed or widened. Crop each one to a similar shape first for a clean result.
That limit is the main thing to know. It is a quick layout helper, not a full collage app with templates, borders or captions.

Notes for US users
- Facebook Marketplace and Craigslist let you add several photos, but a single combined image can serve as a cover shot.
- For a printed 5x7 or 8x10 collage, 1000 by 750 pixels is small. Expect softness if you enlarge it much.
- Get permission before posting photos of other people, especially children, on public pages.
Limits and what to double-check
- •Maximum of four images, and the layouts are fixed.
- •Photos are stretched to fit each cell without preserving proportions, which can distort faces and objects.
- •The output size is fixed at 1000 by 750 pixels, so it is better for screens than prints.

Frequently Asked Questions
How does the Photo Collage Maker work?▼
The Photo Collage Maker runs 100% inside your web browser using modern client-side JavaScript. It performs calculations, conversions, and document processing locally on your device without sending any data to external servers.
Is this photo collage maker completely free to use?▼
Yes. This tool is completely free with no usage limits, no subscriptions, and no registration required.
Is my data private when using the Photo Collage Maker?▼
Yes. Because all operations execute locally on your computer or phone, your inputs, documents, and data never leave your browser.
Why do my photos look stretched?▼
Each image is scaled to fill its slot exactly, regardless of its original shape. To avoid distortion, crop your photos to the same proportions as the cell first. A 4:3 crop fits the grid and stacked layouts well, while side-by-side cells are closer to portrait.
How many photos can I add?▼
Up to four. Selecting more than four keeps only the first four. The side-by-side and stacked layouts use two pictures, and the grid uses all four. Pick the layout after choosing your files.
Can I change the background and gaps?▼
Yes. A color picker sets the background that shows between and around pictures, and a spacing control sets the gap. White looks clean for most photos, while a dark color can make bright photos stand out.
What size is the finished collage?▼
It is always a 1000 by 750 pixel image, regardless of your source photos. That is plenty for social posts and messages, but small for printing. For prints, use a layout tool that supports larger canvases and keep the original files.
