Implementing truly usable PDF text editing in web applications has always been a technical challenge. ElasticPDF was created for this exact purpose—a pure front-end JavaScript PDF text editing SDK built on PDF.js. It is cross-platform, framework-agnostic, and requires no backend support, enabling professional-grade PDF editing directly within the browser.

Whether it is for a SaaS platform, enterprise intranet system, or application scenarios requiring private or offline deployment, ElasticPDF can cover all requirements with a single front-end codebase.

1 Edit PDF Text Like Word

1.1 Add, Delete, and Modify Text

ElasticPDF supports editing all existing text content within a PDF, including:

• Arbitrarily deleting, replacing, and adding text.

• Supporting paragraph operations such as carriage returns and line breaks.

• Supporting special text styles like colored text, superscripts, and subscripts.

1.2 Multilingual and Multi-Character Set Support

• Supports ASCII character input (English, etc.).

• Full support for non-ASCII characters such as Chinese, Japanese, and Korean.

• Ideal for internationalized, multilingual PDF editing scenarios.

In terms of user experience, it is almost identical to editing a Word document, while the final output remains a standard PDF file.

2 Intelligent Adaptive Text Layout

ElasticPDF provides adaptive text capabilities:

•  Adjust text box sizes.

• Automatically reformat text content.

• Avoid overflow and misalignment—common issues in traditional PDF editing.

This ensures that PDF text editing is no longer a painful process of fine-tuning coordinates, but a visual and controllable experience.

3 Support for Rotated PDF Text Editing

Editing rotated text in PDFs has always been a major difficulty for editors.

ElasticPDF supports:

• Rotating PDF text at any angle and saving it.

• Editing existing rotated text objects at any angle.

• Full support for 90° / 180° / 270° and other special angle text.

Whether it's table titles, vertical text, or unique layouts, they can all be correctly parsed and edited.

4 Built-in Professional PDF Annotation Features

In addition to text editing, ElasticPDF provides complete PDF annotation capabilities:

• Highlight, Underline, Strikethrough.

• Pen Tool, Signatures.

• Rectangular, Polygonal, and other graphic annotations.

• Support for parsing and editing original annotations already in the PDF.

This makes ElasticPDF suitable for PDF scenarios involving review, markup, and collaboration.

5 Visual PDF Page Management

ElasticPDF allows for more than just text edits; it supports visual operations for PDF pages:

• Move pages Up, Down, Pin to Top, or Pin to Bottom.

• Add or Delete pages.

• Extract specific pages to generate a new PDF.

This meets the needs of complex PDF page processing for contracts, reports, exam papers, and archives.

Summary

ElasticPDF breaks free from the constraints of servers and complex runtime environments, achieving almost all core PDF editing needs in a pure front-end environment. It brings PDF editing back to its simplest, safest, and most controllable technical form.

The SDK can be directly integrated into the following frameworks, allowing for write once, reuse anywhere—a single codebase covers all platforms:

• Vue

• React

• Angular

• Flutter

• Any front-end or hybrid application framework

If you are looking for:

• A PDF text editing SDK that is non-SaaS dependent, with complete data sovereignty.
