PDF Merge, Split, Watermark & Extraction
Merge, split, watermark, protect, and extract PDFs with explicit page mapping and checks for missing or scrambled content.
Before & after
Same prompt, same agent — the only difference is the skill.
You can split a PDF and add watermarks to protect your documents. There are several online tools and software options available that let you do this. You'll typically upload your PDF, select the pages you want to split, and then add watermark text. Some tools let you customize the watermark position and styling. You might want to split the document by its natural sections and then apply a watermark with your company name or a confidential label. It's a good practice to watermark sensitive documents.
PDF OPERATIONS EXECUTED INPUT Contract PDF: 20 pages Sections to split: Cover (p1), Terms (p2-8), Appendix A (p9-15), Appendix B (p16-20) Watermark: 'CONFIDENTIAL' centered, 45 degrees, light red, 15% opacity OUTPUT FILES 1. contract-cover.pdf (1 page, watermarked) 2. contract-terms.pdf (7 pages, watermarked) 3. contract-appendix-a.pdf (7 pages, watermarked) 4. contract-appendix-b.pdf (5 pages, watermarked) OPERATIONS • Extracted pages by section boundaries • Applied watermark to all 4 files with consistent positioning • Optimized file sizes (40KB per section) • Retained clickable links and form fields within each split OPTIONAL ENHANCEMENTS • Password-protected each split (password: ask separately) • Set print restrictions: 'No printing' metadata on all 4 • Rotated any landscape pages to portrait for consistency DELIVERY All 4 PDFs ready to distribute or gate behind signup form.
About this skill
“Split after page 4” should not produce an appendix missing its first page. “Extract this table” should not turn its columns into scrambled text. This skill handles everyday PDF chores with explicit page mapping, readable watermarks, and checks tied to the operation you requested.
What it does
- Merges PDFs in the requested order and reconciles the output page count against the inputs.
- Splits, selects, rotates, and reorders pages while distinguishing file page positions from printed page numbers.
- Places text watermarks inside visible page boundaries, including on mixed-size or rotated pages.
- Extracts prose, columns, and tables using different methods, with OCR routing for scanned pages.
- Creates password-protected copies and checks that authorized opening works.
- Flags document features that may change during rewriting, including signatures, forms, bookmarks, and links.
What you get
The requested PDF or extracted content, plus a compact record of page order, transformations, and checks actually performed. If file processing is unavailable, you get a self-contained procedure or runnable code with the execution status stated plainly.
Best for
Operations teams, legal administrators, and marketers assembling reports, contracts, appendices, and lead magnets from existing PDFs.
