What is Merge PDF?
When a project is scattered across five different PDFs — a cover letter, three reference documents and a signed form — sending them separately makes the recipient do extra work. Merging combines every file into one document, in the exact order you choose, so whoever opens it only has to click once.
This tool works entirely in your browser. Each PDF you add is read locally, stitched together into a single file, and handed back to you as a download — nothing is transmitted to a server in the process, which matters if any of the pages contain private information.
How to merge pdf in 3 steps
Add your PDFs
Drag in two or more PDF files, or select them from your device. You can add more at any point before merging.
Drag to reorder
Rearrange the files by dragging their thumbnails until the order matches what you want in the final document.
Merge and download
Click Merge, and the combined PDF is generated instantly and ready to download.
When to use it
Freelancers use this to combine an invoice, a signed contract and supporting receipts into a single client-ready file. Students merge separate chapter scans into one study document instead of juggling a folder of individual pages.
HR teams merge an offer letter with its attachments before sending a single file to a new hire, and real estate agents combine listing photos, disclosures and contracts into one packet for a buyer.
Tip: If you only need to combine specific pages rather than whole documents, use Extract PDF Pages on each file first, then merge the results — this keeps the final file smaller and more focused.
