Pro Tips for Merging PDFs
- ✓Compress after merging: After combining files, run the merged PDF through the Compress PDF tool to reduce the total file size before sharing.
- ✓Check page order carefully: Review the file list before clicking merge. It is much faster to reorder files before merging than to split and re-merge afterwards.
- ✓Remove unwanted pages first: Use Split PDF to trim out unnecessary pages from each source document before merging.
- ✓Consistent page sizes: For the most professional result, ensure all source PDFs use the same page size (A4 or Letter) before merging.
- ✓Protect the merged file: If the merged document is sensitive, use the Protect PDF tool to add password protection before sharing.
