About Merged PDF
A merged PDF consolidates multiple document streams into a cohesive single file, simplifying printing, emailing, archiving, and digital signing.
When to Use PDF vs Merged PDF
Merge PDFs when assembling job applications, compiling monthly expense reports, submitting legal filings, or bundling contracts into a single deliverable.
