Getting started
What is Mosaci Studio?
Mosaci Studio is a web-based tool that converts photos into mosaic coloring pages and color-by-number artwork. Upload a photo, pick a mosaic style, and export a print-ready PDF in seconds.
Do I need to install anything?
No. Mosaci runs entirely in your browser. No download, no plugin, no software installation required.
What file formats can I upload?
Mosaci accepts JPG, PNG, and WebP images. For best results, use clear photos with good contrast and a well-defined subject.
How long does conversion take?
About 5 seconds per photo, processed directly in your browser.
Features
What mosaic styles are available?
Mosaci offers 10+ mosaic grid styles including hexagonal, square, and diamond patterns. Each style produces a distinct visual effect from the same source photo.
Does Mosaci add numbers to the coloring cells?
Yes. Each cell in the mosaic grid is automatically numbered and a matching color key is included in the exported PDF.
Can I upload multiple photos at once?
Yes. You can bulk upload an entire folder of photos for batch conversion — ideal for KDP coloring book production. Photos are processed in parallel, so converting a full folder takes about as long as converting a single photo. Each photo still uses one credit.
Pricing & plans
Is Mosaci free?
Yes. Every account gets 10 free credits every month with no credit card required.
How do credits work?
Mosaci is pay-per-use — no subscription. One credit equals one mosaic generation. Buy a credit pack when you need more; purchased credits never expire.
Do I need to cancel anything?
No. There is no subscription to cancel — credit packs are one-time purchases. Buy more only when you need them.
KDP & publishing
Can I use Mosaci to publish coloring books on Amazon KDP?
Yes. Mosaci exports print-ready PDFs formatted for Amazon KDP paperback interior requirements, including correct dimensions and bleed.
Can I sell coloring pages I create with Mosaci on Etsy?
Yes. Pages and books created with Mosaci can be sold as digital downloads or printed products on Etsy and other platforms.
Are the exported PDFs high resolution?
Yes. Mosaci exports PDFs at 300 DPI, the print-quality resolution required for professional printing and KDP publishing.
Do exported PDFs have a watermark?
No. Every export is watermark-free — free and paid credits alike — and ready to publish or print as-is.
Support & policies
What happens if a generation fails?
If a generation fails and no usable output is produced due to a platform issue, contact us and we will restore the consumed credit or issue a refund — you do not need to take any other action.
Can I get a refund?
Unused credit packs are eligible for a refund if requested within 14 days of purchase and no credits from that pack have been consumed. See our Refund Policy for full details.
