Why Do Portals Enforce a 200KB File Limit?
Institutional servers receive millions of candidate documents each year. Storing uncompressed, high-DPI scans of resumes, certificates, and ID cards puts severe bandwidth and storage constraints on their infrastructure.
To maintain lightning-fast response times and prevent server crashes during high-traffic deadlines, web developers configure upload forms with strict 200KB thresholds.
The Risk of Cloud-Based Compressors
Most traditional online PDF compressors require you to upload your resume, passport copy, or tax return to external remote servers. This introduces serious privacy risks, potential data leaks, and compliance violations.
DocSwift solves this problem by using WebAssembly to compress the internal streams of your PDF directly inside your web browser. Your private documents never leave your laptop or smartphone.

Frequently Asked Questions
Will text remain sharp and legible after compression?
Yes! Vector typography and fonts are preserved. Compression focuses on eliminating invisible metadata and resizing oversized scan images.
What if my file is still above 200KB?
If your PDF contains dozens of high-resolution color pages, consider splitting unnecessary pages with our Split PDF tool before compressing.
