IDEAS FOR YOUR PHOTOS

Photo mosaics for families, trips, and anniversaries

Choose a main image and the photos that will fill it. The same photo collection can produce different mosaics depending on your main image and placement settings.

01

Family photo mosaic

Use a family portrait as the main image and photos of your time together as tiles. Zoom into the result to explore the individual pictures.

02

Travel photo mosaic

Recreate a landscape using pictures from your trip. A collection with varied colors and brightness gives the generator more tiles to choose from.

03

Anniversary photo mosaic

Combine photos of your time together into a single image. Save the PNG, or send a mosaic file so others can inspect the tiles.

Make a photo mosaic in three steps

STEP 01

Choose main photo

Select a main photo. JPG, PNG, WebP and GIF are supported; animations have separate output limits.

STEP 02

Choose tile photos

Choose up to 500 photos for photo tiles. Leave this step empty if you only need blur or pixelation.

STEP 03

Configure and create

Choose tile placement or blur/pixelation and the area to process. Still results save as PNG; animated results save as GIF.

Placement method

Histogram compares brightness distributions. Random uses each photo once in a random order, then repeats the list.

Smart placement compares colors and their distribution across regions. Photo diversity adjusts reuse and neighboring repetitions. Compare it with histogram placement in the preview.

Photo editing and partial mosaics

Crop, resize, and layer photos to create your main image. Noise reduction, sharpness, brightness, and contrast adjustments are also available.

Select rectangular regions, or use the brush after generation to reveal tiles only where you paint. The eraser restores the main photo in those areas.

Before you start

Can I use it without tile photos?

Leave the tile step empty and enable mosaic strength in settings to use Soft (blur) or Hard (pixelation). Add tile photos if you want a photo mosaic.

Are my photos or results stored on a server?

Images are processed in the current browser. Photos and results are not saved on our server. Reloading clears the session, so download your result first.

Can it process animated images?

GIF and animated WebP inputs are supported, with GIF output. Output dimensions, duration and frame count are limited and may be adjusted automatically. Brush editing is not supported for animated results.

Can enhancement recover missing detail?

Enhancement adjusts noise, sharpness, brightness and contrast. It does not reconstruct faces, text or textures missing from the original.

Do I need to pay or sign up?

The service is free to use without signup or separate installation. Support is optional and is not required to use the editing features.
