Tips for Better Results
Before You Merge
- Make sure all your PDFs are properly oriented before merging
- Check page sizes - mixing letter and A4 sizes may affect printing
- Consider the file size of your final document if you need to email it - use the Compress PDF tool to shrink it afterward
If you need to rearrange individual pages after merging, use our Reorder Pages tool. And if your merged PDF ends up too large for email, check out our guide on how to compress PDFs without losing quality.
Working with a large PDF that needs to be broken apart instead? Our Split PDF tool lets you divide a document into separate files. You can also delete unwanted pages from any PDF, or add page numbers to your merged document for a polished, professional result.
