Design Your Collage Now

Three steps

Add your images

Drop in your images or browse for them — JPEG, PNG, and WebP up to 50 MB each. Works best with 15 or more images. You can mark up to 3 as featured and they will get more space in the collage.

Pick a format

Choose a print size (30×40 cm, A3, 50×70 cm…) or a screen format (Full HD, 4K, square). The tool suggests a resolution that hits 300 DPI at your chosen size with the images you have — you can always override it.

Create and save

Hit Create. The layout is generated entirely on your device — nothing is uploaded. When it finishes, download it as a full-resolution PNG or JPEG. Each run finds a different layout — create again any time, but save the ones you like first.

Good to know before you start

15+ images works best

With only a handful of images the layout can't always avoid gaps around the edges. More images give the program more combinations to explore — and more chances to fill the collage completely.

Each run finds a different layout

The layout algorithm is non-deterministic by nature — every run explores a different set of candidate arrangements. If the first result has gaps, try again. If it keeps falling short, the format or image count is the limiting factor.

Download as PNG or JPEG

Save a lossless PNG, or a smaller JPEG at a quality you control. You choose the pixel dimensions; the tool tells you the resulting DPI at your selected print size. Resolutions up to 16 000 × 16 000 px are supported on desktop.

Common questions

Will my images be uploaded to a server?

No. Everything runs in your browser tab using WebAssembly. Your images are read from your local disk into browser memory and never transmitted anywhere. The server only serves the app files — it never sees your images or the resulting collage. After each collage we do send a small amount of anonymous performance data (device class, solve duration, coverage) to help improve the layout engine — but never your images. See the privacy policy.

How many images do I need?

A minimum of 3, but 15 or more gives the best results. With few images, gaps around the edges are more likely. Up to 300 images are supported.

Can I make a specific image appear larger?

Yes. In the editor, tap any image and choose ×2 or ×3 to give it more space in the collage. Up to 3 images can be featured at once.

What can I export?

A full-resolution image at whatever pixel dimensions you choose — a lossless PNG, or a JPEG at a quality you control. For print, the tool suggests dimensions that achieve 300 DPI at your selected paper size.

How long does it take?

Usually 15 – 60 seconds, depending on image count and your device. The algorithm runs in parallel across all your CPU cores. No internet connection is needed once the page has loaded — processing is entirely local.
