# Fast PDF APP: Merge Documents — Indexed Packets and Bookmarks > Indexed Packets and Bookmarks (iPhone/iPad app by Robert Corbin.) - Source: https://appshunter.io/ios/app/fast-pdf-app-merge-documents/id6761960212 (this page in markdown: same URL + `.md`) - Developer: [Robert Corbin](https://appshunter.io/developer/1890247992) - Category: Productivity, Utilities - Price: $3.99 - Age rating: 4+ - Requires: iOS 17.0 · 30 MB - Languages: American English - Released: 2026-04-10 - Data updated: 2026-10-09 ## What is Fast PDF APP? Document Packets assembles source PDFs into one organized handoff with a linked contents page, optional dividers, section bookmarks and a companion source map. HOW IT WORKS 1. Open Document Packets from the home screen. Add source PDFs from Files, or explore the clearly labeled sample packet. 2. Name and reorder the sections, select the source page ranges, and choose whether to include section dividers. 3. Build the packet, preview the indexed PDF and share it with the source map. Finished packets remain in the local library until you delete them. Scanning, OCR, page organization, merging, extraction, stamps, signing, redaction, password-protected copies and image export remain available. Packet assembly stops on missing pages rather than silently omitting them, and source files remain untouched. WHAT TO KNOW Up to 20 unencrypted source PDFs, 50 MB per source, 150 MB total input and 400 selected source pages. Imported page sizes and rotations are checked after assembly. A packet is a new PDF: original digital signatures are not preserved, and forms, links and other interactive content need recipient verification. Page numbers are one-based. Source hashes identify exact input bytes without certifying document authenticity. iPhone and iPad. ## Is Fast PDF APP safe? Not enough ratings yet to assess Fast PDF APP. ## Is Fast PDF APP legit?

The checklist covers page count, filename cleanup, destination, OCR, estimated file size, tag, and paper size. **Clearer readiness states** - Export choices now show whether the scan is ready, needs a quick check, or requires a fix before saving. **Better workflow guidance** - Multi-page scans warn when OCR is off, large exports flag the estimated size, and untagged files are called out before they get lost in History. **Updated documentation and screenshots** - The App Store packet, support website, privacy page, and screenshot set have been refreshed for the current interface. Privacy unchanged: scanning, OCR, PDF creation, merge, tags, and preflight all run locally on the device. ### 2.0 — 2026-06-24 Fast PDF 2.0 — a pro upgrade adding a full PDF Toolkit, still 100% offline. Open any PDF from History (swipe right or long-press → PDF Tools). Every tool writes a new file and keeps your original: • Organize Pages: drag to reorder, tap to rotate, swipe to delete. • Split / Extract pages by range ("1, 3-5, 8") or by tapping. • Page Numbers & Bates numbering in any corner. • Watermark: flattened diagonal or horizontal text with adjustable opacity. • Sign: draw your signature and flatten it onto a page. • Redact: drag black boxes that truly rasterize the page so text underneath is gone for good. • Password Protect: an AES-encrypted copy with a strength meter. • Pages → Images: export each page as JPEG or PNG at your chosen DPI. No account, no network — everything happens on your device. ## Apps similar to Fast PDF APP | App | Rating | Price | Category | | --- | --- | --- | --- | | [PDFOut](https://appshunter.io/ios/app/pdfout/id6760473465) | — | Free | Productivity | | [Officiate Teleprompter](https://appshunter.io/ios/app/officiate-teleprompter/id6778214612) | — | Free | Productivity | | [ScanTo Pro: Offline PDF & OCR](https://appshunter.io/ios/app/scanto-pro-offline-pdf-and-ocr/id6779977651) | 3.0 (2) | Free | Productivity | | [FastScan2PDF](https://appshunter.io/ios/app/fastscan2pdf/id6772603983) | — | Free | Productivity | | [PaintXDesign](https://appshunter.io/ios/app/paintxdesign/id6772518565) | — | Free | Productivity | | [Blanc Note](https://appshunter.io/ios/app/blanc-note/id6758005069) | — | Free | Productivity | ## More apps by Robert Corbin - [Daily Word Journey](https://appshunter.io/ios/app/daily-word-journey/id6761548266) - [Hush Secret Text: Encryption](https://appshunter.io/ios/app/hush-secret-text-encryption/id6761658175) - [Renew Guard](https://appshunter.io/ios/app/renew-guard/id6761755447) - [Receipt to PDF: Expense Report](https://appshunter.io/ios/app/receipt-to-pdf-expense-report/id6761782025) - [Route Your Pay: Mileage Log](https://appshunter.io/ios/app/route-your-pay-mileage-log/id6761783719) - [Tip Arbiter: Tip Calculator](https://appshunter.io/ios/app/tip-arbiter-tip-calculator/id6761786879) All apps by Robert Corbin: https://appshunter.io/developer/1890247992 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
