The 100KB Standard for National Recruitment Portals
Major national examination boards across India—including the Institute of Banking Personnel Selection (IBPS), Staff Selection Commission (SSC), Railway Recruitment Boards (RRB), and Central Teacher Eligibility Test (CTET)—consistently specify 100KB as their maximum file limit for document attachments.
Submitting an uncompressed PDF that exceeds 100KB triggers immediate server validation errors, blocking candidate registration. Our dedicated 100KB compressor is calibrated to meet these exact portal constraints while preserving document authenticity.
Balancing Visual Clarity with Strict Size Limits
Reducing an oversized 5MB scan to under 100KB requires careful optimization. Standard compression software frequently blurs crucial details such as issuing authority stamps, serial numbers, and candidate signatures.
Our tool solves this by applying selective bi-cubic downsampling to 150 DPI for embedded raster images while keeping typography vector-clean. Redundant font subsets and invisible XML metadata are stripped away, yielding maximum size reduction with zero compromise on visual legibility.
Safe for Financial and Academic Records
Educational degree certificates, salary slips, and government identity cards contain confidential details that should never be uploaded to remote cloud converters. Etool Mitra processes all documents locally in your browser memory using WebAssembly.
Your files remain completely private, are never sent over the internet, and are permanently erased from memory the moment you refresh or close your browser tab.
