AI PDF and document SDK
Enables developers to embed full‑featured PDF capabilities directly into web, mobile, or desktop applications. The SDK provides a programmable viewer that supports smooth scrolling, zoom, and text selection without external plugins. It offers editing tools for inserting, deleting, and rearranging pages, as well as modifying text, images, and annotations. Conversion functions turn PDFs into Word, Excel, or HTML files while preserving layout. OCR engine extracts searchable text from scanned documents, and digital signature APIs add compliance‑grade signing. Beyond basic manipulation, PDFTron includes redaction tools that permanently remove sensitive data and compliance reports that log changes. Form handling lets developers render, fill, and extract data from interactive PDF forms using JavaScript or server‑side calls. Collaboration APIs enable real‑time annotation sharing across users, while cloud storage connectors sync documents with AWS S3, Azure Blob, or Google Drive. An AI‑powered search module indexes content, allowing keyword and semantic queries across large document sets. The SDK supports C#, Java, JavaScript, Swift, and Kotlin, ensuring cross‑platform deployment. Typical users are software developers building document‑intensive products, legal teams automating contract workflows, and enterprises digitizing archives. The free tier grants access to core viewing and annotation features, sufficient for prototyping or low‑volume apps. Paid plans unlock unlimited conversions, OCR, redaction, and priority support, scaling with usage. Compared with Adobe PDF Services, PDFTron offers tighter on‑premise control and broader language bindings, while remaining competitive on performance. Documentation includes sample code, API reference, and a sandbox environment, reducing integration time to a few days.
