Choose two or more PDFs, arrange them with ▲ ▼, and tap Merge PDFs. You get one combined PDF with every page in the order you chose.
Getting documents right for online forms
- Check the exact limit first. Portals state the format (PDF or JPG) and a maximum size such as 100 KB, 200 KB or 1 MB. A file even 1 KB over is rejected.
- Scan at 150–200 DPI. That is sharp enough to read and keeps files small. 600 DPI scans only make files bigger.
- Upload only the pages asked for. Remove blank or extra pages with Organise PDF before compressing.
- Password-protected PDFs (for example e-Aadhaar or bank statements) must be opened and saved without a password before most portals — and these tools — can use them.
- Name files clearly, e.g.
10th_marksheet.pdf, and open the final file once to check every page is readable.
How to merge pdf files into one
- Choose the PDFs (you can add more later).
- Reorder them with ▲ ▼ or remove any with ✕.
- Tap Merge PDFs — the combined file downloads.
FAQs
How do I merge PDFs on my phone?
Open this page in Chrome or Safari, choose your PDFs, put them in order and tap Merge. The merged file downloads to your phone.
Is there a limit on files?
No fixed limit. Very large files depend on your device memory; for exam forms, merging a few documents is instant.
The merged PDF is too big for the form — what now?
Run it through Compress PDF with your form's KB limit.
Are my files uploaded to a server?
No. The tool runs entirely in your browser using JavaScript — your files never leave your phone or computer, so they stay private.
