PDF Toolkit helps you manage everyday documents such as receipts, contracts, forms, study notes, invoices, scans, and long PDF files. Instead of letting files pile up in a messy list, you can organize, edit, review, and reuse your documents in a cleaner way. Organize Documents More Clearly Create custom categories for different projects, dates, document types, clients, school subjects, or personal needs. When your PDFs are placed where they belong, it becomes easier to find the right file without scrolling through a cluttered document list. Find Important Files Faster Use color tags to mark important PDFs, such as urgent contracts, paid receipts, travel documents, or files that need follow-up. You can filter by tag color to quickly return to the documents that matter most. Prepare PDFs for Sharing or Saving Combine separate PDF files into one complete document, making it easier to share scans, receipts, reports, or chapters together. You can also extract selected pages from a long PDF and save them as a new file, so you only keep or share the pages you actually need. Reuse Text from Scans and Images With OCR text recognition, PDF Toolkit helps you extract text from images or PDF pages and turn recognized content into new PDF files. This is useful when you need to reuse information from scanned notes, receipts, forms, screenshots, or paper documents. Review Documents with Notes Highlight, underline, or draw directly on PDFs while reading. Mark key points in contracts, reports, manuals, study materials, or personal files, so important details are easier to find later. Local and Simple Document Handling PDF Toolkit is designed for local PDF management. Core document operations can be completed on your device without forced uploads. Camera and file permissions are requested only when you choose to scan, import, open, or save documents. PDF Toolkit gives you a simple way to keep your documents tidy, reduce file clutter, and handle daily PDF tasks more efficiently.
