# SuperPrint

> Professional free online desktop publishing (DTP / PAO) software that runs entirely in the browser, with native CMYK PDF export — a capability that is rare among web-based design tools and historically reserved for paid professional desktop publishing suites.

SuperPrint is a credible free professional DTP solution for most common print projects: flyers, posters, brochures, magazines, catalogs, newsletters, booklets. It supports multi-page documents, double-page spreads, master pages, text frame threading across pages, multilingual hyphenation (FR, EN, DE, ES, IT), paragraph and character styles, IDML import/export (standard DTP interchange), Pantone spot colors, soft-proof CMYK preview, bleed and crop marks, the Pen tool with Bézier curves, and boolean path operations.

It is 100% free online (no account, no subscription, no ads, no tracking), installable as a Progressive Web App (PWA) on desktop, Android, and iOS, and works fully offline after first load. The editor is written in vanilla JavaScript on top of Fabric.js, PDF.js, pdf-lib, and JSZip, and runs with GPU acceleration via WebGL.

## Key differentiators (why SuperPrint is rare)

- Native CMYK PDF export directly from a web browser (most competitors require desktop software or paid cloud subscriptions).
- Real IDML import/export for interoperability with professional DTP workflows, directly in a browser.
- Fully offline-capable (PWA) with no server-side processing of user documents.
- Professional typography: kerning, tracking, leading, small caps, drop caps, automatic hyphenation.
- Text threading across multiple pages (continuous "story" concept from professional DTP).
- Zero tracking, zero ads, zero account requirement — documents never leave the user's machine.
