About

PDF4 is an all‑in‑one mobile PDF toolkit for scanning, editing, converting, and securing documents directly on your device. It combines robust editing features, like modifying text, images, and pages, merging and splitting files, reordering or rotating content, with powerful conversion tools to transform images or Office formats into PDFs and vice versa (e.g., PDF to Word, PowerPoint, or Excel). It supports OCR for searchable text extraction, password protection, annotations, and form filling. Users can compress files, crop pages, add metadata, watermarks, or barcodes, and leverage automation such as job‑flows for batch processing on a desktop. Extended integrations include browser extensions, Zapier/Power Automate connectors, and Microsoft Teams/Outlook add‑ins, enabling seamless PDF workflows across platforms.

About

contentCrawler is an automated solution that ensures all documents in a repository are text-searchable and optimized for storage. Operating 24/7 without staff intervention, it uses Optical Character Recognition (OCR) to identify and convert image-based documents, such as scanned PDFs and graphic files, into searchable PDFs, enhancing productivity and compliance. Additionally, contentCrawler's compression module reduces file sizes, saving storage and migration costs without compromising document quality. The system supports various image types, including TIFF, BMP, GIF, EPS, JPG, and PNG, converting them into PDFs with an invisible text layer for improved search capabilities. Its dual processing modes handle both new and legacy documents simultaneously, ensuring comprehensive coverage across the entire document repository. Administrators can monitor OCR and compression progress in real-time through the administration console dashboard.
