Set your book up once
A Comic Project holds the trim size, bleed, safe area, resolution, page count and cover of one book. Open any tool inside it and the numbers are already there. Check DPI, validate a PDF, calculate the spine, tick off the print checklist, and every result is saved with the book.
Create a free projectShared settings
Trim, bleed, DPI and page count flow into every tool automatically.
Private by default
Projects are yours alone. Uploads are never public and never used for training.

Calculators load with almost no JavaScript; PDF and image parsing runs on your machine.

Saved results build a history of checks you can hand to a printer.
