Mosaic Effect turns a photo into a mosaic made of large color tiles, a bit like a picture built from small pieces of colored glass. It gives artwork, posters, profile pictures and social media posts a bold, artistic look in a few seconds.
You enter an amount that controls the effect, and the default is 50. The tool processes the whole picture and gives you a new file, so your original stays untouched. Each file can be up to 20 MB, and there is nothing to install and no account is needed.
How to use Mosaic Effect
- Click the upload field and choose your image (up to 20 MB).
- Enter the amount, or keep the default of 50.
- Press Generate and wait a moment.
- Download the mosaic picture and compare it with the original.
Tips for better results
- Pictures with bold colors and simple shapes work best, because the tiles keep the main shapes recognizable.
- Try several amounts to find the balance between a recognizable picture and an artistic one.
- Start from a large, high-quality original if you plan to print the result.
- Keep your original photo, so you can run the tool again with a different amount.
