Choose a PDF, pick A4 (or Letter/Legal) and a margin, and tap Resize pages. Each page is scaled to fit and centred — nothing is cropped, and text stays selectable.
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.

FAQs
Does resizing to A4 reduce quality?
No. Pages are scaled as vector content, so text and lines stay sharp.
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.
