It incorporates DSC-based digital signing capabilities that enable users to sign multiple PDFs at once through a batch mode.

Moreover, PDFSign includes a powerful PDF Toolbox that encompasses various features such as merging, splitting, reordering, extracting, rotating, cropping, compressing, and repairing PDFs; editing text; inserting images and text; as well as annotating, highlighting, and redacting content. Furthermore, users can enhance their documents by adding watermarks, headers, footers, and page numbers, carry out OCR, convert PDFs into popular document and image formats, and fill out forms. This wide-ranging set of tools ensures that users can handle all aspects of PDF management effectively and efficiently, making PDFSign an indispensable ally for anyone working with PDF documents.

KeptPDF is a browser-based PDF processing solution that operates entirely on your local device. This means there’s no need for uploads: every feature, including redaction, optical character recognition (OCR), compression, signing, splitting, and merging—along with an impressive suite of 25 tools—functions seamlessly without sending your documents to a server. Its advanced redaction technology automatically identifies sensitive information such as names, Social Security numbers, phone numbers, addresses, and dates, effectively removing the original text rather than merely obscuring it. Each processed file is accompanied by a verifiable audit certificate for added security. Additionally, a command line version is available to efficiently handle large volumes of PDFs in a single operation, catering to the needs of scanning bureaus, litigation support teams, and records management departments. The essential features can be accessed for free without any registration required.
