Pro Tips for Merging PDFs

💡 Organize Before Merging

Rename your PDF files with numbers or prefixes (01_, 02_, etc.) to make ordering easier during the merge process.

💡 Check File Compatibility

Ensure all PDFs are properly formatted and not corrupted before merging. This prevents errors in the final document.

💡 Consider File Size

If the merged PDF is too large for email, use our PDF compression tool afterward to reduce the file size.

💡 Maintain Consistency

For professional documents, ensure all PDFs have consistent page sizes and orientations before merging.
