# Extract Pages — Technical Tool Documentation > **Summary:** Copy selected page numbers or ranges into a new PDF. > **Tool Route:** `/tools/extract-pages.html` > **Visual Guide Route:** `/guides/extract-pages/` > **Category:** Organize PDF > **Processing Architecture:** 100% Client-Side. Zero server uploads. --- ## 1. What the Tool Does Extract Pages copies the page numbers you specify into a new PDF while preserving their sorted order. **Requirements & Constraints:** One readable PDF is required. Enter page numbers or ranges such as 1-3, 5, 8-10. --- ## 2. When to Use It Use **Extract Pages** whenever you need to perform client-side organize pdf operations without uploading confidential records to third-party cloud servers. **Ideal Scenarios:** - Working on personal identity records, banking statements, medical filings, or NDAs requiring 100% local confidentiality. - Fast offline or low-bandwidth processing directly in your web browser. - Universal cross-platform document operations on Windows, macOS, Linux, Android, or iOS. --- ## 3. Key Implemented Features - **Engine Architecture:** `pdf-lib (PDFDocument.create, copyPages, addPage)` - **Zero Server Uploads:** Processing executes directly within client browser memory. - **Instant Processing:** Fast execution powered by WebAssembly and native HTML5 APIs. - **Review Previews:** Visual feedback and progress indicators confirm results prior to saving. - **No Sign-up / No Watermarks:** Full functionality with zero paywalls or forced branding. --- ## 4. Supported Input Files - **Primary Input:** Single PDF document (.pdf) - **Validation:** Files are validated in the browser prior to parsing. --- ## 5. Supported Output Files - **Output Format:** Isolated PDF document (extracted-pages.pdf) - **MIME Types:** `application/pdf` (or appropriate image/text/zip formats). --- ## 6. File Size & Memory Limits - **Recommended Bounds:** Client RAM bound (~100 MB recommended) - **Technical Context:** Modern browser tabs enforce memory quotas (typically 1.5 GB to 2 GB per tab). PDFHub handles documents comfortably within standard browser memory limits. For files exceeding 150 MB or 1,000 pages, splitting into smaller sections is recommended. --- ## 7. Step-by-Step Instructions 1. **Upload a PDF and note the page count shown.** 2. **Enter the pages or ranges you want to keep.** 3. **Select Extract Pages.** 4. **Open the generated PDF and confirm the selected pages.** --- ## 8. Required User Inputs & Controls - **File Upload Area (`#drop` / `#fin`):** Click to open native file browser or drag and drop supported files. - **Tool Options (`#opts`):** Dynamic settings panel configuring parameters, page ranges, or compression levels. - **Execution Button (`Extract Pages (#goBtn)`):** Triggers client-side processing pipeline. - **Reset Button:** Clears loaded files and resets workspace to pristine state. --- ## 9. Processing Behavior & Execution Pipeline Reads source PDF, maps comma-separated target page numbers, initializes a target PDFDocument, copies only the requested page indices, and outputs a clean standalone PDF. --- ## 10. Expected Output & Download Verification - Upon successful execution, the interface triggers an automated browser download via `downloadBlob()` or opens a result review modal. - Users can verify file size, page count, and visual rendering before finalizing the download. --- ## 11. Practical Example Use Case Extracting just the signature page and contract addendum from a long legal mortgage document. --- ## 12. Common Errors & Troubleshooting - **Issue:** If no pages are extracted, use valid numbers within the displayed range. - **Issue:** If parsing fails, try a fresh readable PDF. - **Avoid:** Entering zero-based page numbers; the interface uses page 1 as the first page. - **Avoid:** Assuming excluded pages remain in the output. - **Tip:** Leaving the page input field empty. Solution: Provide page numbers or ranges (e.g. 1-3, 5). - **Tip:** Targeting non-numeric characters. Solution: Use digits, hyphens, and commas only. --- ## 13. Privacy & Data Handling Architecture - **Local Processing:** 100% Client-Side. Zero server uploads. - **Browser Memory:** Document bytes reside temporarily in `ArrayBuffer` memory and are garbage collected when the browser tab is refreshed or closed. - **Cookies & Telemetry:** PDFHub sets zero tracking cookies, zero analytics beacons, and stores zero personal document data. --- ## 14. Frequently Asked Questions (FAQ) #### Q: Can I preserve page order? **A:** Yes, selected pages are written in ascending order. #### Q: Does extraction modify the original? **A:** No. --- ## 15.
