Coloring pages from your own world
Linecraft is a small studio tool for parents, teachers and grown-up colorists. Store-bought coloring books are full of other people’s characters; we think the best page is the one with your dog, your street, or a kid’s own name in giant bubble letters.
How the pages are made
Bubble letters and name pages (free)
Letters are built as real vector outlines in your browser: we take each glyph from an open-licensed font (SIL Open Font License or Apache 2.0), puff it outward with rounded joins, keep the holes in letters like “a” and “o” open, layer overlapping letters so each stays readable, and add a 3D side for the 3D and graffiti styles. Nothing is uploaded and nothing costs us money to run, which is why it’s free.
AI coloring pages (credits)
For photos and text ideas we use a commercial image model, then run our own print clean-up: the result is converted to pure black and white (no gray), lines are slightly thickened so crayons don’t cross them, specks are removed and the page is scaled to 2400 px — about 300 DPI on a full page. Pages that come back gray or filled in are rejected and your credit is returned automatically.
The free gallery
Every gallery page is an original design made for Linecraft, reviewed by a person, and cleaned with the same pipeline. We don’t publish licensed characters.
Photos and privacy
- The instant sketch runs entirely on your device — your photo never leaves the browser.
- For AI pages the photo is sent once to the image model and then dropped. We never store it and never use it for training.
- Finished pages stay in “My creations” for 30 days, visible only to you, then they’re deleted.
Linecraft is made for adults. It isn’t directed to children under 13, and we don’t knowingly collect their information.
