Frequently Asked Questions
Why does SSC CGL online form require files under 50KB?
Government portals receive millions of uploads. Enforcing a 50KB limit keeps their servers fast and their databases manageable for officials who review applications.
Will my text still be legible after compressing to 50KB?
Yes. Our algorithm uses content-aware compression that prioritises text sharpness and contrast so your document remains clear and readable.
Is my personal document safe when I upload it?
Absolutely. We process files in an isolated temporary session and auto-delete them within 15 minutes. We never read, store, or share your data.
My PDF has 50 pages — can I still compress it to 50KB?
It depends. A single-page scan can reliably reach 50KB. For multi-page PDFs, try removing unnecessary pages first or scanning in black-and-white mode.

No. Utilifyx does not add any watermarks. Your compressed PDF is clean and ready for official submission.
Can I use this on my phone without installing anything?

The 50KB Challenge: Navigating Indian Government Portals with Ease
If you're an aspirant for government jobs in India, you've likely encountered the frustrating "File size must be between 10KB and 50KB" error message. Whether it's the SSC, UPSC, or state-level PSCs, the 50KB limit is a standard mandate for uploads.
Why 50KB is the Standard
Government servers handle millions of applications. By enforcing a 50KB limit, portals ensure their databases remain manageable and load quickly. For users, however, compressing a high-quality scan down to 50KB without blur is a technical challenge.
