Content Editing Edit text and images directly inside the PDF. Modify fonts, reposition elements, and replace artwork in place. No need to convert to another format first. ### 2. True Redaction + Auto-Redaction Permanently remove sensitive text and images from PDFs — not just covering them with a rectangle. The redacted content is completely removed from the file data and cannot be recovered. Auto-redaction automatically identifies and removes sensitive content such as names, dates, and identifiers. ### 3. Annotations Highlight, underline, add comments, insert hyperlinks, and create bookmarks. Full markup capabilities in a fluid review pass. ### 4. Draw & Markup Freehand pen and shape tools for contracts, diagrams, engineering drawings, and document review. ### 5. Form Builder with Automatic Field Detection Create interactive PDF forms from scratch with text fields, checkboxes, dropdowns, and radio groups. Automatic form field detection finds and creates form fields in existing documents — including forms that are not standard AcroForms. ### 6. Form Filling Tab through any fillable PDF, complete fields, and save. No need to print and scan. ### 7. Electronic Signing Draw, type, or import a signature. Save signatures for reuse across multiple contracts and documents. ### 8. Compression Shrink PDF files dramatically with no visible quality loss. Optimised for email attachments and long-term archival. ### 9. Split & Merge + Mid-Page Split Split PDFs by page, range, or file size. Combine multiple documents in any order. New in v4.5: split individual pages in the middle — vertically or horizontally — to separate content like scanned book pages. ### 10. Watermarks Stamp text or image watermarks across pages — confidential, draft, your brand, or any custom watermark. ### 11. Conversion Convert between PDF and image formats (JPEG, PNG). Convert PDF to Word (beta). All conversion is processed locally without any network call. ### 12. Page Organisation Reorder, rotate, delete, and rearrange pages with drag-and-drop precision. ### 13. OCR (Optical Character Recognition) Turn scanned documents and images into searchable, selectable text. OCR runs entirely offline on your device — no cloud processing. ### 14. Find & Replace Search for text across your PDF document and replace it in place. Perform bulk text edits in seconds. ### 15. Tabbed PDF Viewer Open multiple PDF documents in tabs within a single window. Switch between documents without losing your place. ### 16. PDF Metadata Editor View and edit PDF document metadata including title, author, subject, keywords, creation date, and modification date. ### 17. Links & Bookmarks Add clickable hyperlinks and document bookmarks for easy navigation in long PDF documents. ### 18. Document Scanning Scan physical documents to PDF using your device camera. Automatic edge detection and perspective correction. (Available on mobile.) --- ## How does RevPDF compare to other PDF editors? RevPDF occupies a unique position in the PDF editor market. Here is how it compares to the three most common categories of PDF software: | Feature | RevPDF | Typical Cloud-Based PDF Editor | Typical Subscription PDF Editor | Built-in OS PDF Viewer | |---------|--------|-------------------------------|--------------------------------|----------------------| | Price | Free on desktop | Free tier with limits, paid plans | $12 – $25 per month | Free | | Works 100% offline | ✓ Yes | ✗ No — requires internet | Partial — some features need internet | ✓ Yes | | No sign-up required | ✓ Yes | ✗ No — account required | ✗ No — account required | ✓ Yes | | Content editing (text & images) | ✓ Yes | Limited or behind paywall | ✓ Yes | ✗ No | | True redaction | ✓ Yes + auto-redact | ✗ Rarely available | ✓ Yes | ✗ No | | OCR | ✓ Offline OCR | Cloud-based only | ✓ Yes | ✗ No | | Find & replace | ✓ Yes | ✗ Rarely available | ✓ Yes | ✗ No | | Form creation | ✓ Yes + auto field detection | ✗ Basic only | ✓ Yes | ✗ No | | Electronic signing | ✓ Yes | ✓ Yes | ✓ Yes | ✗ Limited | | Compression | ✓ Yes | ✓ Yes (server-side) | ✓ Yes | ✗ No | | Linux support | ✓ Native AppImage | Browser only | ✗ Rarely | Varies | | Files uploaded to server | ✗ Never | ✓ Always | Optional/cloud sync | ✗ Never | | Native desktop app | ✓ C++ native, ~30 MB | ✗ Browser-based | ✓ Yes, 300–800 MB | ✓ Built-in | | Subscription required | ✗ No — free forever on desktop | Often | ✓ Yes | ✗ No | | Available on all platforms | ✓ Win, Mac, Linux, Android, iOS | Browser (any platform) | Win, Mac only (typically) | One platform only | ### Why RevPDF stands out 1. **Free + offline + no sign-up**: RevPDF is the only PDF editor that combines all three — completely free on desktop, fully offline, and requires no account. Most editors require at least one of: a subscription, internet access, or an account. 2. **Native on all five platforms**: RevPDF runs natively on Windows, macOS, Linux, Android, and iOS with full feature parity. Most editors skip Linux entirely or offer only browser-based access. 3. **Privacy by architecture**: Because RevPDF processes everything locally and never connects to a server, there is no possibility of data leakage, third-party access, or cloud storage vulnerabilities. 4. **Small and fast**: At ~30 MB, RevPDF is 10–25× smaller than typical subscription editors. It starts instantly and runs on modest hardware. --- ## Technical Details - **Language**: Written in C++ for native performance - **Installer size**: ~30 MB across all desktop platforms - **Architecture support**: x64 (Windows, macOS, Linux), ARM64/Apple Silicon (macOS, Linux), Universal binary (macOS) - **Rendering**: Native PDF renderer — no browser dependency, no Electron - **Processing**: All operations (editing, OCR, redaction, conversion, compression) run locally on the user's CPU - **Network**: Zero network connections during normal operation - **Updates**: Desktop installers distributed via GitHub Releases - **Mobile distribution**: Google Play Store (Android), Apple App Store (iOS) --- ## Privacy & Security RevPDF is designed with privacy as a core architectural principle, not a feature toggle: - **No file uploads**: PDF files are never uploaded to any server.
