PDF Toolbox is an app that works 100% offline and includes merge, split, compress, protect, unlock, OCR, rotate, resize, and camera to PDF functionality. It remains free with no subscription, no ads, no tracking, and no need to upload PDFs to the internet.
PDF Toolbox is a free, all-in-one offline PDF editor designed for iPhone, iPad, and Mac users who demand professional document tools without monthly subscriptions or cloud uploads. Categorized as a Productivity app, it delivers over 20 tools including merge, split, compress, OCR, sign, watermark, and redaction—all running 100% on-device using Apple's native PDFKit and CoreGraphics. Its core value is absolute privacy: no data collection, no tracking, and no internet required. Originally a rebuild of a PDF unlocker, the app now offers a comprehensive suite that handles everything from basic page organization to advanced security and conversion. Developed by Yung Kei Simon MA and available in 16 languages, the app is compact at only 13.3 MB and supports iOS 17.1+, iPadOS 17.1+, and macOS 15.1+.
Many users need to edit PDFs but hesitate to upload sensitive documents to third-party servers or pay for expensive subscriptions. PDF Toolbox eliminates these concerns by providing a complete offline solution: all processing happens locally using Apple's frameworks, so documents never leave the device. This is critical for legal contracts, medical records, financial statements, or any confidential information that must stay private. The app also solves the cost problem by being completely free—no subscriptions, no ads, and no in-app purchases required for functionality. Instead, it offers a voluntary tip jar for those who want to support development. Users can seamlessly merge invoices, split large reports, compress presentations for email, or add password protection without worrying about data leaks or monthly bills.
The first major feature group is the Organize suite, which includes Merge, Split, Rotate, Reorder, Extract, and Delete pages. Merge combines multiple PDFs into a single document, ideal for consolidating chapters, invoices, or scanned pages into one file. Split allows dividing a PDF by page range or extracting individual pages—perfect for breaking a large document into smaller sections. Rotate and Reorder let users fix page orientation and arrange pages in any sequence, while Extract creates a new PDF from selected pages and Delete removes unwanted content. These tools run locally using Apple's PDFKit, providing instant, offline processing without compromising document integrity or privacy.
The Optimize feature group focuses on reducing file size, adjusting dimensions, and repairing issues. The Compress tool reduces PDF size by optimizing images and content, making files suitable for email or storage-limited devices. Resize allows users to set page dimensions to standard sizes (e.g., Letter, A4) or custom values—useful for formatting documents for specific printers or submissions. The Flatten tool merges annotations, form fields, and comments into the page content, preventing further edits and ensuring a final, immutable version. A standout feature is Repair PDF (BETA), which uses tolerant parsing and Apple Core Graphics to reconstruct damaged PDFs from scratch, outputting a clean, well-formed document without relying on third-party libraries. Batch processing is supported for these tools, with detailed progress tracking for efficiency.
