LEADTOOLS PDF Developer Toolkit

LEADTOOLS PDF provides PDF APIs to read, write, raster-view, and update PDF files on all major platforms. With the PDF toolkit, developers can extract text, images, hyperlinks, and metadata from PDF files. The SDK also provides complete control of pages in existing PDF documents. Conversion to PDF/A documents that are ready for archival can be done in a few lines of code. Additionally, with the included LEADTOOLS PDF Optimizer, PDF files can be made web-ready with linearization and compression.

LEADTOOLS PDF includes all features of Imaging, such as 165+ formats, compression, image processing, viewers, TWAIN and WIA scanning, and more. This combination of PDF and imaging features makes the LEADTOOLS PDF an extreme value.


What's Included in the LEADTOOLS PDF SDK?


Open and edit content within PDF files.

Digital signatures in PDF files are comparable to ink signatures on a paper document, but much more secure. LEADTOOLS PDF SDK libraries can add digital signatures to PDF files, retrieve information from embedded signatures, as well as verify signatures to ensure that a bad actor has not manipulated the PDF. When combined with the eSignature support integrated in the LEADTOOLS Document Viewer, developers also have the ability to add simple electronic signatures to the PDF before creating the digital verification certificate.
