How to compress PDF to under 100KB or 200KB for government forms?

Select your PDF file and choose High or Extreme compression. KraftDoc automatically recalculates document streams inside browser memory to fit under strict limits like 100KB, 200KB, or 300KB required by SSC, UPSC, and State examination portals without losing text clarity.

Is it safe to compress National ID, Tax ID, or document PDFs here?

Yes. Unlike typical online converters, KraftDoc processes your file 100% locally in your device's browser using WebAssembly. Your confidential documents are never uploaded to any remote server or cloud storage.

Does compressing reduce the quality of certificates or signatures?

No. The local compression engine selectively resamples oversized images while keeping text fonts, signatures, and stamps sharp and readable for official portal verifications.

How In-Browser Compression Works

PDF files often carry heavy redundant font dictionaries, uncompressed metadata, and duplicate object references. KraftDoc recompiles and re-indexes these object streams directly inside your browser’s virtual engine without sharing your data across cloud servers.

Compress PDF for Online Portals & Government Applications

Most competitive examination and official recruitment portals across India (such as UPSC, SSC, IBPS, State PSC, and Railway recruitment) require documents like documents, caste certificates, and National ID cards to be uploaded under strict limits—typically under 100KB, 200KB, or 300KB. KraftDoc optimizes these documents on-device without compressing text into unreadable scans.

Target: 100KB

Identity Proofs

Ideal for National ID cards, Tax IDs, and voter IDs that require small file footprint with crisp text.

Target: 200KB

Documents & Degrees

Keeps 10th/12th grade certificates and multi-semester scorecards clearly readable for verification officers.

Zero Server Upload

100% Data Privacy

Processed entirely in local memory (RAM). No data ever leaves your device or lands on foreign servers.
