How to use it
- Tap “Select PDF files” and choose two or more PDFs. You can add more files later.
- Put the files in order with the up and down arrows, and remove any you don't need.
- Tap “Merge PDFs”. You'll see the total number of pages and the final file size.
- Tap “Download merged PDF” to save the combined file as merged.pdf.
Why merge PDFs?
Many application portals give you just one upload slot for a whole group of documents — for example “educational certificates” or “supporting documents”. If your 10th marksheet, 12th marksheet and degree certificate are separate PDFs, you have to combine them into one file first. Merging also helps when you email documents, send them on WhatsApp, or submit KYC, loan and visa paperwork as a single attachment.
What stays the same after merging
- Quality: pages are copied exactly as they are — nothing is re-compressed, so text and images look identical.
- Selectable text: if you could select or search the text in the original PDF, you still can.
- Page size and orientation: A4, Letter and landscape pages keep their own size.
- Bookmarks and fillable form fields from the originals may not carry over — fill in forms before merging.
- The one exception: PDFs with copy or edit restrictions are added as page images. They look the same, but their text can't be selected (see below).
A sensible order for exam and admission documents
If the official notification gives an order, always follow it. If it doesn't, reviewers usually find this order easiest to check:
- Class 10 marksheet or certificate (it also proves your date of birth)
- Class 12 marksheet
- Graduation and post-graduation marksheets or degree
- Category certificate (SC / ST / OBC / EWS), if applicable
- Domicile, disability or other certificates the form asks for
- Photo ID proof
Is the merged file too big?
Portals often cap uploads at a few hundred KB or a couple of MB. Merging adds the sizes together, so a set of scanned certificates can easily cross the limit. Shrink the merged file with Compress PDF — for example to 500 KB or 1 MB. Have photos instead of PDFs? Turn them into a PDF with JPG to PDF first, then merge.
Restricted and password-protected PDFs
Many official PDFs are restricted: they open normally, but copying or editing is switched off. You can still merge them — the tool marks them in the list and adds their pages as high-quality images, so they look exactly the same.
A few PDFs — e-Aadhaar and some bank statements, for example — need a password just to open. Those can't be merged, and the tool marks them clearly. You can usually make an unlocked copy by opening the file with its password, choosing Print → Save as PDF, and adding that copy instead.
Private by design
Your files are merged inside your browser. They are never uploaded, so marksheets, IDs and bank documents stay on your phone or computer.
