💡 Tips for Best Results
Frequently Asked Questions
Why does MCA21 ROC e-filing portal require files under 150KB?
Government portals receive millions of uploads. Enforcing a 150KB limit keeps their servers fast and their databases manageable for officials who review applications.
Will my text still be legible after compressing to 150KB?
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 150 pages — can I still compress it to 150KB?
It depends. A single-page scan can reliably reach 150KB. 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.
Mastering the 150KB Limit for Professional Portals
The 150KB limit is large enough for a high-quality scan of an ID card, yet small enough to keep server costs low for institutions. If you're registering a company on MCA21 or filing for GST, this threshold is your frequent companion.
Why Readability Matters
In corporate compliance, an ROC officer or GST inspector needs to clearly see seals and signatures. Our 150KB compressor prioritizes Character Recognition (OCR) quality while stripping metadata.
