TNPSC Certificate Upload Manual: Community, Nativity & PSTM PDF Compression (Under 200 KB)

When registering for Tamil Nadu Public Service Commission (tnpsc.gov.in) recruitment drives—including Group 1, Group 2/2A, Group 4, and Village Administrative Officer (VAO)—applicants must upload multiple educational and revenue certificates to their One Time Registration (OTR) profile. The TNPSC portal enforces an uncompromising ceiling: every certificate must be a single PDF file strictly between 100 KB and 200 KB. Uploading raw smartphone camera scans (which often weigh 3 MB to 8 MB) triggers an immediate server rejection error. Conversely, using aggressive generic compression tools blurs university roll numbers and invalidates the official digital signature seal. You can safely compress and verify your certificates using Kagazo's free TNPSC OTR Compliance Kit and TN Marksheet Compressor.

Key Takeaways

• Strict File Bounds: All educational and reservation certificates uploaded to TNPSC OTR must be in PDF format, weighing strictly between 100 KB and 200 KB. Files under 100 KB or over 200 KB are blocked.
• PSTM 2021 Amendment: Persons Studied in Tamil Medium (PSTM) preference requires certificates covering 1st Standard up to the prescribed educational qualification issued strictly in the new prescribed annexure format.
• Digital Signature Green Tick: Revenue certificates issued via TNeGA e-Sevai (Community, Nativity, Income) must retain authentic cryptographic verification markers.
• Marksheet Merging: Multi-semester grade cards must be compiled chronologically into a single unified multi-page PDF under 200 KB before upload.
• Zero Document Storage: Kagazo compresses and verifies certificates entirely inside device RAM memory using WebAssembly; no personal identity documents are stored.

How to Compress TNPSC Certificates Under 200 KB Without Roll Number Blur

Kagazo uses targeted WebAssembly quantization and font stream preservation rather than crude raster downsampling, ensuring text stays razor-sharp under 200 KB.

Generic online PDF compressors treat your certificates as flat photos and indiscriminately lower DPI, turning 6-digit roll numbers and Controller of Examinations signatures into illegible grey smudges. During TNPSC Certificate Verification (CV), administrative officers immediately flag blurred documents.

Kagazo resolves this through a client-side three-stage pipeline:

1. Background Noise Isolation: Eliminates scanner grain and shadows while boosting pure monochrome contrast.
2. Vector Preservation: Keeps embedded PDF font dictionaries and digital signature metadata intact.
3. Calibrated Packaging: Locks the final output file strictly between 120 KB and 180 KB, comfortably inside TNPSC's safe acceptance window.
