When Do You Need to Combine PDFs?

Managing multiple PDF files is a common headache. Maybe you have a cover letter and a resume as separate files. Maybe your client needs one document but you've been working in parts. Combining PDFs into a single file makes sharing, printing, and archiving far simpler.

PDFix lets you merge PDFs in seconds — no software installation, no account, no cost. Simply upload, order, and merge. After combining, you can also reduce the file size if the merged PDF is too large to email, or add a watermark to protect it.
