Create, Edit Rich Text & Export to PDF

A new generation of WYSIWYG online PDF editor, allowing you to edit and create PDF document streams just like editing Word documents.

This tool is a pure front-end, high-fidelity, native vector-level online typesetting and PDF export system. Moving beyond the legacy limitations of traditional front-end html2canvas screenshot-to-PDF workflows—which often suffer from blurry rendering, unselectable text, and bloated file sizes—this modern Online Document to PDF Builder combines the power of Quill and pdfmake to deliver a true WYSIWYG PDF Editor Online experience with crisp, native vector outputs.

Below is a comprehensive guide to the key features, architecture, and capabilities of this cutting-edge Client-side PDF Generator.

1. Rich Text Content Editing and Multimedia Typesetting

Hierarchical Typography and Text Formatting

• Structured Multi-Level Headings: Instantly configure standard body text (P) and five levels of headings (H1 to H5), paired with quick font size adjustments (Small, Medium, Large, Extra Large).
• Styling and Alignment: Full support for standard formatting including Bold (B), Underline (U), Strikethrough (S), custom text colors, and background highlight markers. Features comprehensive paragraph alignment (Left, Center, Right, Justify), ordered/unordered lists, and blockquotes.
• Hyperlinks and Multilingual Typography: Seamlessly insert hyperlinks and render multi-language text (The PDF editor supports a wide range of languages, such as: English, عربي, Deutsch, Español, Français, हिंदी, Indonesia, Italiano, 日本語, 한국어, Português, Русский, แบบไทย, Türkçe, Tiếng Việt, 简体中文, 粵語中文, 繁體中文.) alongside full-color vector emojis and Unicode symbols without missing glyphs or rendering artifacts.

Multimedia and Image Processing

• Multi-Format Import: Native support for JPG, PNG, WebP, and SVG vector graphics, along with direct clipboard image pasting via Ctrl + V.
• Interactive Sizing Controls: Clicking any image reveals a floating toolbar offering drag-to-resize handles, percentage-based sliders (e.g., Width: 60%), and one-click 'Auto Width' adjustments in real time.

Structured Data Table Engine

• Flexible Layout and Operations: Rapidly insert tables with an interactive floating property bar for adding or deleting rows and columns with a single click.
• Advanced Cell Customization: Supports multi-cell merging, splitting, custom border colors, cell-level font colors, and background fill styling.

2. Advanced Font Management System

To eliminate common client-side PDF generation issues such as garbled characters, missing glyphs ('tofu' boxes □), and licensing risks, this WYSIWYG PDF Editor Online incorporates a robust font management engine:

• System Fonts: Instantly leverage local and OS-installed fonts for lightweight, rapid compilation.
• 100% Free Commercial Font Library: Pre-integrated with popular open-source, commercially safe fonts (such as Source Han Sans, Korean typography, and diverse Latin fonts) with live UI previews, file size indicators, and loading statuses.
• Custom Font Uploads: Upload custom font files (.ttf, .woff, .otf) to embed brand-specific typography directly into your exported PDF documents.

3. Precise PDF Page Setup and Layout Rules

Page Setup and Millimeter-Level Margins

• Standard Formats and Orientation: Built-in standard paper presets (e.g., A4: 210 × 297 mm) with one-click toggling between Portrait and Landscape layouts.
• 4-Way Precision Margins: Independently adjust Top, Bottom, Left, and Right margins with millimeter accuracy to meet strict print layout standards.

Custom Anti-Counterfeiting Watermarks

• Quick Toggle: Easily enable or disable watermarks on demand.
• Multi-Parameter Customization: Configure watermark text, font color, size (with auto-fitting), opacity (0.0 to 1.0), rotation angle (e.g., -45°), and bold styling.

Three-Zone Header and Footer System

• Independent Three-Zone Layout: Headers and footers are divided into Left, Center, and Right zones for versatile metadata placement.
• Dynamic Page Numbering: Insert dynamic macros such as $p/$P to automatically render formatted page counts (e.g., Page 1/10).

Interactive Document Outlines and Table of Contents (TOC)

• Hierarchy Depth Control: Specify the exact heading levels (e.g., H1–H5) extracted into the document directory.
• Native PDF Bookmarks (Outlines): Automatically generate an interactive bookmark tree in PDF readers for fast navigation in long documents.
• Embedded Table of Contents (TOC): Generate a visual, indexed Table of Contents directly on the cover or initial pages with a single click.

4. Core Output Capabilities and Technical Advantages

• Native Vector PDF Generation (Client-Side): Unlike canvas-based screenshot tools, this Client-side PDF Generator directly compiles native vector primitives and text streams. The resulting PDFs feature selectable, copyable, and fully searchable text.
• Lossless Scaling and Compact File Sizes: Vector typography and SVG elements remain crisp at any zoom level, producing significantly smaller file sizes compared to image-heavy alternatives.
• Zero Server Uploads & Maximum Data Privacy: All layout computation, font parsing, and PDF compiling happen entirely inside the user's browser, keeping sensitive data private and secure.
• Native Print Support: Directly trigger the browser's native print protocol for an instant, true WYSIWYG hard-copy output.
