Expert techniques for combining PDF documents efficiently
Name your files with numbers (01_intro.pdf, 02_chapter1.pdf) for easier sorting. This saves time when arranging multiple documents.
Preview individual pages before merging to catch any issues. Remove unwanted pages (like blank pages) before combining.
For very large documents, merge related sections first, then combine the section PDFs. This gives you better control over the final structure.
Enable bookmark preservation when merging to maintain table of contents and navigation from original documents.
Ensure all pages have consistent orientation before merging. Use our Rotate PDF tool first if some pages are landscape.
If your merged PDF is too large, use our Compress PDF tool afterward to reduce file size without quality loss.
