Compressing PDFs for Government and Job Portals

Many Indian government application portals, such as UPSC, SSC, NSDL, and state-level recruitment boards, impose strict file size limits (usually under 100KB or 200KB) for certificates, marksheets, and identity proofs. Compressing these documents without making them unreadable is a common challenge. 100kb.in uses advanced client-side compression algorithms that optimize internal PDF streams, downsample embedded scanned images, and strip metadata. Crucially, it preserves all vector text structures and fonts. This guarantees that your text remains sharp and 100% legible for official verification, while satisfying the portal's file size constraint safely in your browser.

Frequently Asked Questions

Common questions regarding file security, dimensions, and portal regulations:

Will compressing my PDF make the text blurry or unreadable?
No, our optimizer targets image elements and document overhead first. It preserves vector text structures and embedded fonts, so all text remains crisp and highly legible even at extreme compression levels.
Can I compress a password-protected PDF?
No, password-protected or encrypted PDFs cannot be processed client-side without entering the password. Please decrypt the file first before uploading it.
Is my document safe from being leaked?
Absolutely. All processing occurs locally in your web browser using client-side JavaScript. No file data is ever uploaded to a server, ensuring your personal certificates and marksheets remain 100% confidential.
