# SuperPrint > Professional 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 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 (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 online with no subscription (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. - **Homepage**: https://superprint.cc/ - **Publisher**: Zigmoon — https://zigmoon.com - **License**: Proprietary, use online without subscription - **Languages**: English (default), French, Japanese - **Version**: 1.7.349 (September 2026) ## Core documentation - [Main app](https://superprint.cc/): The SuperPrint editor itself (opens directly in the browser). - [User documentation](https://superprint.cc/documentation.html): Feature reference, keyboard shortcuts, workflow guides. - [Landing page](https://superprint.cc/landing.html): Overview of features and positioning. - [CMYK convert tool](https://superprint.cc/super-print-cmyk-convert.html): Dedicated PDF CMYK conversion utility. - [CMYK landing](https://superprint.cc/cmyk-landing-secure.html): Specialized landing page for CMYK workflow. - [Full LLM context](https://superprint.cc/llms-full.txt): Extended reference for AI assistants. ## Import / Export formats - **Import**: PDF, DOCX (Word), ODT (OpenDocument), RTF, IDML, SLA (open-source layout format), SVG, JPEG, PNG, WebP. - **Export**: PDF (RGB or CMYK with bleed and crop marks), PNG, JPG (ZIP for multi-page), IDML, native `.sp` project file. ## 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 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.
