Image Collage
Free online image collage maker. Combine photos using layout templates or long image stitching. Add annotations, watermarks and export as JPG or PNG.
How many images can I add to a collage?
You can add up to 16 images in layout mode. For long image stitching, there is no limit on the number of images.
What image formats are supported?
All common image formats are supported including PNG, JPEG, WebP, BMP and GIF. You can export as high-quality JPG or lossless PNG.
Is my data uploaded to a server?
No. All image processing happens locally in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy.
Can I add watermarks to my collage?
Yes! Enable the watermark option in Advanced settings. You can customize the text, font size, opacity, rotation angle and density.
What is the difference between Layout and Long Image modes?
Layout mode arranges images in grid templates (2-16 images). Long Image mode stitches images vertically or horizontally into a single long image with no quantity limit.

How does the image processing work technically?
The tool uses HTML5 Canvas API for all image rendering and compositing. Images are drawn onto a canvas element, annotations are overlaid, and the result is exported using canvas toDataURL or toBlob methods.
Do I need to install any software?
No installation needed. The tool runs entirely in your web browser. Just open the page and start creating your collage immediately.
Does it work on mobile devices?
Yes, the tool is fully responsive and works on smartphones, tablets and desktop computers. The interface adapts to your screen size automatically.
How to Use Image Collage
Combine multiple photos into one collage using layout templates or long-image stitching, then export as JPG or PNG. Everything runs locally in your browser, so your images never leave your device.
- Click Upload (or the Upload Images area) and pick the photos to combine; remove any unwanted image with the Remove button.
- Pick a density preset — Sparse, Medium, or Dense — to control how many cells the layout template creates.
- Fine-tune the look with Gap and Radius, and choose a Background color for the canvas.
- Adjust the outer margins W, H, T, R, B and L if you want extra padding around the collage.
- Type your signature into the Watermark Text field (placeholder “Enter text…”) and set the Font Size.
- Open the Custom Layout dialog to hand-place cells, confirm with Ok, then export via HD JPG, JPG, or PNG — Reset Defaults restores the original settings.
Use HD JPG when the collage is dense or large: the export keeps more detail and watermark text stays crisp.
