Before you begin: system requirements & safety
- Check that your operating system meets the app’s minimum requirements (Windows, macOS, or Linux versions as specified).
- Download only from the official website or a trusted app store to avoid bundled adware or malware.
- If PDF Cube Free requests access to online storage or external accounts, review permissions and privacy terms before granting access.

Interface overview
- Toolbar: Contains common actions like Open, Save, Print, Undo/Redo, and common editing tools.
- Sidebar: Shows thumbnails, bookmarks, attachments, or the document outline for easy navigation.
- Main pane: Where the PDF pages render. Use mouse wheel or trackpad gestures to scroll and pinch-zoom if supported.

Opening and navigating PDFs
- Open a file: Click File → Open or drag-and-drop a PDF into the main window.
- Navigate pages: Use the scrollbar, page thumbnails, or keyboard arrows. Jump to a page by entering its number in the page box.
- Search text: Use the Find box (Ctrl/Cmd+F) to locate words or phrases. Advanced search (if available) can match case or whole words.
Basic editing features
Note: Feature availability may vary by version. PDF Cube Free focuses on essential edits.
- Text edits: Select the text tool, click on editable text, and type replacements. If the PDF is a scanned image, you may need OCR (optical character recognition) if the free version includes it.
- Annotations and comments: Use highlight, underline, strikeout, sticky notes, and drawing tools to mark up documents. Right-click annotations to edit properties like color or opacity.
- Fillable forms: Click fields to type into forms. Save after completing to retain entered data.
- Images: Insert, replace, or delete images where allowed. Drag to reposition and use corner handles to resize.
Page management
- Split a PDF: Choose the Split tool, specify page ranges or split by size, and export separate files.
- Merge PDFs: Use the Merge or Combine tool to add multiple files, reorder them, and save a single merged PDF.
- Reorder/delete pages: Open the thumbnail view, drag pages to reorder, or select and delete unwanted pages.
- Rotate pages: Select one or more pages and use rotate controls to correct orientation.
Conversion and export
- Export to other formats: If included, export PDFs to Word, Excel, images (PNG/JPEG), or plain text. Conversion quality depends on document complexity.
- Print to PDF: Use Print → Save as PDF to create a new PDF from any printable document.
- Optimize/compress: Use Reduce File Size or Optimize tool to shrink large PDFs for sharing—review quality settings to balance clarity and file size.
Security and signing
- Password protection: Use Encrypt or Protect tool to add a password for opening or editing the PDF. Choose strong passwords and keep them secure.
- Redaction: Permanently remove sensitive text or images with the redaction tool; remember redaction is irreversible once saved.
- Digital signatures: Sign documents digitally or verify signatures if the feature is present. Follow prompts to create or import a certificate.
Using OCR (if available)
- OCR converts scanned pages into selectable, searchable text.
- Run OCR on a page range or entire document, then proofread converted text—OCR accuracy varies with scan quality and fonts.
Tips for efficient use
- Use keyboard shortcuts: Common ones include Ctrl/Cmd+O (Open), Ctrl/Cmd+S (Save), Ctrl/Cmd+P (Print), and Ctrl/Cmd+F (Find).
- Keep a recent files list enabled for quick access.
- Save incremental copies when making major edits (e.g., document_v2.pdf).
- Use cloud integration if you need cross-device access, but check privacy settings first.
Troubleshooting common issues
- PDF won’t open: Verify file integrity; try opening in another viewer to confirm.
- Editing disabled: The file may be secured or scanned as an image—use OCR or remove restrictions if you have rights.
- Missing features: Confirm you’re using the free edition; some features may be part of a paid upgrade.
When to upgrade to a paid PDF tool
Consider upgrading if you need:
- Advanced editing of complex layouts without conversion errors.
- Batch processing for large numbers of files.
- Professional-grade OCR and export fidelity.
- Enterprise security, audit logs, or advanced e-signature workflows.
Quick workflow examples
- Fill and sign a contract: Open → Fill form fields → Add signature → Save as signed_copy.pdf.
- Merge reports: File → Combine → Add files → Reorder → Save merged_report.pdf.
- Create a smaller shareable file: File → Optimize/Compress → Choose quality → Save compressed.pdf.
Final notes
