Combining multiple PDF documents into a single file is a daily task for office workers, students, and CSC operators. Whether you are merging certificates for a job application, combining pages of a scanned document, or creating a single submission file for a government portal, knowing how to merge PDFs efficiently saves time.

When Do You Need to Merge PDFs?

Common situations include combining multiple scanned pages of a single document (like a land record or mark sheet), merging all required documents for a government application (Aadhaar + PAN + photo + signature in one PDF), creating a single project report from multiple chapter files, and combining invoices or receipts for accounting purposes.

How to Merge PDFs on PC Tool Hub

Open the Merge PDF tool. Upload all the PDF files you want to combine — you can drag and drop multiple files at once. Arrange the files in your desired order by dragging them up or down. Click Merge and download the combined PDF. The entire process happens in your browser — no files are uploaded to any server.

Rearranging Pages Before Merging

If you need to rearrange individual pages (not just whole files), use the Rearrange PDF Pages tool after merging. This lets you drag individual pages to reorder them, which is useful when you have multi-page scans that got mixed up.

File Size After Merging

The merged PDF will be approximately the sum of all input file sizes. If the result is too large for your upload requirement, use the Compress PDF tool afterwards to reduce the file size while keeping content readable.

Security and Privacy

All PDF merging is done entirely in your browser using JavaScript. Your documents are never sent to any server. This is critical when working with sensitive documents like Aadhaar cards, PAN cards, financial statements, or legal documents.
