Common Recruitment Portal Errors and How Kagazo Fixes Them
Critical failure points prevented by our automated validation engine:
Exceeding 300 KB Ceiling on UPSC Server
Files measuring 300.5 KB are rejected by the UPSC ORA portal. Kagazo enforces a safe 220 KB target.
Pixelated Matriculation Certificate
Over-compression blurs date-of-birth numerals on 10th certificates. Kagazo preserves numeric typography.
Lossy Compression Fading Red & Blue Wax Seals
Crude algorithms destroy color saturation in seals. Kagazo retains authentic chromatic accuracy.
Uneven Scaling in DAF Document Annexures
Combining mixed-size scans creates awkward aspect ratios. Kagazo standardizes all pages to A4.
Frequently Asked Questions
Verified answers regarding exam portal requirements, document security, and file formatting:
What is the PDF file size limit for UPSC Civil Services and ORA applications?
The UPSC Online Recruitment Application (ORA) and Civil Services DAF portals mandate that uploaded document PDFs must be between 100 KB and 300 KB (some forms permit 20 KB to 300 KB). Kagazo locks in a safe 220 KB target.
Will my matriculation certificate date of birth remain clear after compression?
Yes. Kagazo isolates high-frequency text zones so that dates, student names, and board secretary signatures remain crisp and legible for scrutiny committees.
Can I compress my degree certificate and consolidated marksheet together?
Yes! Upload the combined multi-page PDF. The engine optimizes both pages evenly to stay comfortably under the 300 KB ceiling.
Does this tool support OBC Non-Creamy Layer and EWS certificates for UPSC?
Yes. All central government format category proofs, issuing authority seals, and signature blocks are preserved with high contrast.
Are my confidential educational credentials uploaded to any server?
Never. Kagazo processes all PDF documents locally in your browser memory via WebAssembly. Zero files are uploaded or stored remotely.
Does Kagazo add any watermark or logo to the UPSC PDF?
No. The generated PDF is completely clean with zero watermarks, brand stamps, or alterations.
Can I compress documents directly on my smartphone?
Yes. The tool runs smoothly on Android and iOS mobile browsers without requiring any app download.
How does Kagazo handle color saturation in university seals?
Kagazo retains native color gamut coordinates so that colored governmental watermarks, embossed logos, and multi-color university crests remain vibrant.
What should I do if my scanned document is 10 MB?
Upload the file directly. Our engine downsamples the heavy embedded scan to 150–200 DPI, bringing it safely under 300 KB in seconds.
Does this tool work for UPSC NDA, CDS, CAPF, and Engineering Services (ESE)?
Yes. All exams administered by the Union Public Service Commission adhere to these document upload standards.
