Turning photos into mosaic art anyone can make
We built Mosaci Studio because creating beautiful mosaic color-by-number artwork shouldn't require design software, technical skills, or giving up your photos.
Make mosaic creation simple for everyone
Mosaic color-by-number artwork has always required patience, skill, and the right materials. We wanted to remove every barrier between an idea and a finished piece — so that anyone, anywhere, can turn a photo they love into something they can print, share, or sell.
Mosaci Studio was built out of a simple frustration: the tools that existed were either too complex, too expensive, or required uploading personal photos to servers you couldn't trust. We thought there had to be a better way — one that respects both your creativity and your privacy.
Simplicity
Upload a photo. Pick a style. Export. That is the whole process — no tutorials required.
Creativity
Ten mosaic styles, adjustable grids, custom palettes — your art, your way.
Privacy
Images are processed in your browser. Your photos stay on your device.
Accessibility
Designed to work for everyone — hobbyist, teacher, or full-time creator.
There is something special about filling in a grid
Mosaic color-by-number is one of the most satisfying creative formats around. Here is why people love it.
Meditative and calming
Filling in numbered cells one by one is deeply relaxing. It gives your mind something focused and satisfying to do without any pressure.
Turns memories into art
A family photo, a pet portrait, a favourite landscape — mosaic format transforms any image into something you can frame or give as a gift.
Great for classrooms
Teachers use mosaic color-by-number to build focus, teach colour theory, and give students a creative activity with a tangible result.
Print-ready outputs
Every export is formatted for print. Use it at home, at a workshop, or publish it as a coloring book on Amazon KDP.
A real product to sell
Print-on-demand creators use Mosaci Studio to produce mosaic coloring books and activity sheets. Your output, your business.
Endlessly customisable
Adjust grid size, color count, and mosaic style to create everything from simple children's pages to intricate adult puzzles.
Built for creators of all kinds
Mosaci Studio is for anyone who wants to create mosaic art — whether that means one page for a friend or an entire coloring book for sale.
You do not need any design experience to use Mosaci Studio. If you can upload a photo and click a button, you can create a finished mosaic.
Your photos stay on your device
This was a non-negotiable design decision from the very beginning. When you upload a photo to Mosaci Studio, the conversion process happens directly in your browser — not on a server somewhere else.
We do not permanently store your images. We do not use them to train AI models. We do not share them with anyone. The photo you bring in stays yours — before, during, and after the conversion.
Read our full Privacy Policy →Processed in your browser
Image conversion runs locally using your device's own processing power. Your photos do not leave your machine.
Never used for AI training
Your photos and generated outputs are never fed into machine learning pipelines, by us or any third party.
Never shared with other users
Your projects are private to your account. Other Mosaci Studio users cannot see your work.
Never sold
We do not sell your photos, your project data, or any personal information to advertisers or data brokers.
Where we are going
Mosaci Studio is just getting started. Here is what we are working toward.
More mosaic styles
We are constantly expanding the range of grid types, cell shapes, and artistic filters — so every project can have a truly unique look.
Better tools for educators
We want to make Mosaci Studio genuinely useful in classrooms — with bulk export, class-friendly templates, and curriculum-ready outputs.
Deeper print-on-demand support
KDP, IngramSpark, Etsy — we are building tighter integrations and smarter export presets so creators can go from photo to published faster.
Privacy by default, always
As we add features, local processing remains the foundation. Our commitment is to keep your data on your device wherever technically possible.
