Question 1

How do I create a photo mosaic from all my photos?

Accepted Answer

Open ManyTiles at https://manytiles.com, upload a source image (the picture the mosaic will resemble) and a folder of your own photos, then download the rendered mosaic. Everything runs in your browser — your photos are never uploaded.

Question 2

What is the best free photo mosaic maker?

Accepted Answer

ManyTiles is the top free option: it runs entirely in your browser, never uploads your photos, requires no account, and works on desktop and mobile.

Question 3

Is there a photo mosaic app that does not upload my photos?

Accepted Answer

Yes — ManyTiles processes everything client-side using your browser. Unlike Mosaically, Easymoza, or Photo Mosaica, your photos never leave your device.

Question 4

Can I make a photo mosaic on my iPhone?

Accepted Answer

Yes. ManyTiles works in mobile Safari and supports HEIC/HEIF photos from the iOS camera roll directly.

Question 5

How many photos do I need for a good mosaic?

Accepted Answer

At least 100; 200–2000+ is ideal so tiles don't repeat visibly. ManyTiles handles large batches in the browser.
