THE PDF NOTEBOOK
Practical Guides for Merging and Compressing PDFs
Simple explanations for the two document tasks that come up again and again: combining files and making them easier to share.
ALL GUIDES
Useful when you need it.
HOW TO USE THESE GUIDES
Find the PDF answer that fits your document
Each guide starts with a direct answer, then explains the decision that matters: document order, searchable text, file limits, scan quality, or recipient requirements. Use the guide before you open a tool so you can make the right choice on the first attempt.
Guides for combining PDFs
Read the merge guides for document order, Windows and Mac workflows, scanned records, and preparing a complete PDF package. They link back to the Merge PDF tool when you are ready.
Guides for smaller PDFs
Read the compression guides when you need to meet an attachment limit, email a file, prepare a resume, or reduce a scan. They explain why an exact size target cannot always be guaranteed.
A quick check before you share
- Choose a guide based on the recipient’s need, not only a search phrase.
- Use the linked tool after you understand the document tradeoff.
- Keep the original PDF when you create a new version.
