How to Merge Multiple Documents into One PDF

Updated 2026-08-18 · 4 min read

College admissions, job applications and government forms often ask you to upload a single PDF containing several documents — all your marksheets, a set of certificates, or ID proofs front and back. Uploading them one by one won't do. Here's how to combine them into one clean PDF in under a minute.

Merge PDFs, step by step

1. Open the Merge PDF tool.
2. Add all the PDF files you want to combine.
3. Use the ↑ / ↓ buttons to set the order (e.g. 10th marksheet, then 12th, then degree).
4. Click Merge PDF and download the single combined file.

Merging runs entirely in your browser — your documents are never uploaded anywhere, which matters when you're handling marksheets and ID proofs.

Have photos or scans instead of PDFs?

Phone photos and scans are usually JPG or PNG. Convert them to PDF first, then merge:

1. Turn your images into a PDF with the JPG to PDF tool (it puts one image per page).
2. Then combine everything with Merge PDF.

Getting the order right

Applications usually want documents in a specific sequence. Add them in roughly the right order, then fine-tune with the up/down arrows before merging. Name the final file something clear like Rahul_Marksheets.pdf so reviewers can find it.

Keeping the combined file small

Merging several scans can produce a large file that breaks the portal's size limit. If that happens, run the merged PDF through the Compress PDF tool to bring it back under the limit — see our guide on compressing a PDF to 100 KB.
