Frequently Asked Questions
Why does UPSC Civil Services Mains require files under 100KB?
Government portals receive millions of uploads. Enforcing a 100KB limit keeps their servers fast and their databases manageable for officials who review applications.
Will my text still be legible after compressing to 100KB?
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 100 pages — can I still compress it to 100KB?
It depends. A single-page scan can reliably reach 100KB. For multi-page PDFs, try removing unnecessary pages first or scanning in black-and-white mode.
Does the tool add a watermark to my file?
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?
Yes, the tool works entirely in your mobile browser. Just open Utilifyx, upload your file, and download the compressed version — no app required.
