Frequently Asked Questions

How does this tool compress PDFs without making text blurry? ▼

Zenith Growth uses a high-DPI super-sampling canvas engine (150–195 DPI). It intelligently resamples embedded image layers while maintaining razor-sharp vector contours for text and typography.

Are my confidential files uploaded to any servers? ▼

No. The entire compression process takes place locally inside your browser using client-side JavaScript. Your confidential financial records, resumes, and legal papers never leave your device.

Can I compress files under 100KB for government and job portals? ▼

Yes. Select the "Extreme Compression" preset to shrink file sizes to the smallest possible footprint while ensuring critical text remains legible for automated portal validators.
