What this guide helps you do

| Text resume or form | Compress moderately | Formatting, links, page breaks, and contact details |
| Scanned certificate | Compress carefully | Names, dates, stamps, seals, and signatures |
| Phone photo document | Image to PDF, then compress if needed | Blur, shadows, crop edges, and orientation |
| Multiple documents | Merge first, then compress | Page order and whether all required pages are included |
FAQ
Can I use this for UPSC certificate uploads?
Yes. Use it for PDFs that need to be smaller, but always follow the exact official portal requirement.
Will compression change my document?
It can reduce image quality if the target size is very small, so review the final file carefully.
Should I use 100KB for every document?
No. Use 100KB only when the upload instruction asks for it. Scanned documents may need a larger allowed limit.
Can I combine documents for UPSC uploads?
Only combine documents when the form specifically asks for one PDF. Otherwise upload each document separately.
Final upload checklist
- Open the final PDF before uploading.
- Check the file size against the official limit.
- Confirm that all text, photos, stamps, and signatures are readable.
- Use a simple file name without special characters.
- Keep the original document safe in case you need to try again.
