FAQ
Why Merge PDF Files?
Managing multiple separate PDF files is inefficient. University submission portals require a single file. Email clients reject multi-attachment collections. Client portals have file count limits. Merging resolves all of these problems in one step.
The most common use cases our users report:
- Academic submissions — combining a cover sheet, research paper, and bibliography into one file.
- Job applications — merging a CV, cover letter, and portfolio into a single professional PDF.
- Legal documents — assembling signed pages with the full contract body.
- Business reporting — consolidating monthly reports from multiple departments.
- Invoice management — combining a quarter's invoices into a single file for accountants.
