Why Merge PDFs?
Keep related documents together
Combine separate documents into one organized PDF instead of managing multiple files.
Easier sharing
Send one combined document instead of attaching several individual PDF files.
Simplify printing
Put related pages into one document before printing or saving your files.
Prepare files for uploads
Create a single PDF when an application, submission, or workflow requires one document.
PDF Content Is Preserved
The merger combines PDF pages directly rather than converting them into screenshots or other image files. This means the pages are not intentionally rasterized, resized, or converted into images during the merge process.
