Merge PDF Files Free Online — Combine PDFs in Seconds

You've got three separate PDFs that belong together — a cover page, a report body, and an appendix. Or maybe you need to combine scanned receipts into a single expense document. Merging PDFs is one of the most common document tasks, and you shouldn't need to upload your files to a server to do it.

Here's how to merge PDF files free online without compromising your privacy.

Why Merge PDF Files

• Combine related documents: Merge a cover letter with a resume, or a proposal with its appendices.
• Create unified reports: Combine monthly reports into a quarterly or annual document.
• Organize receipts: Merge scanned receipts into a single expense report for accounting.
• Prepare submissions: Many portals require a single PDF for job applications or grant proposals.
• Simplify sharing: Send one PDF instead of multiple attachments.

Split PDFs Too

Need the opposite PDFslime also lets you split PDFs into separate files:
