Frequently Asked Questions

Is it safe to use these PDF tools for sensitive documents?
Yes, absolutely. All 31 PDF tools run 100% client-side in your web browser memory. Your documents, bank statements, and legal files are never uploaded to any external server.
How does the PDF to ZIP Converter tool work?
The PDF to ZIP tool breaks documents into standalone single-page PDFs, chunks pages into sets, renders high-DPI images (PNG, JPG, WebP), harvests embedded photos, and packs everything into a compressed ZIP archive in your browser RAM.
How does the PDF Redaction tool protect private information?
Unlike basic editors that merely draw a black box on top of text, our Redact PDF tool permanently purges and destroys the underlying text and vector paths so confidential data cannot be highlighted or extracted.
Can I merge specific pages from multiple PDF files?
Yes. Our Merge PDF tool features per-document page range filters and an expanded page visual grid, allowing you to reorder, extract, and combine specific sheets seamlessly.
How can I reduce the file size of my PDF for government portals?
Use our Compress PDF or Resize PDF tools to target strict file limits like Under 50 KB, 100 KB, 200 KB, or 500 KB while retaining clear text and signatures.
Are there any daily limits or paid subscriptions?
No. Harsh Cyber Cafe provides unrestricted access with no daily quotas, no hidden watermarks, and no sign-up requirements.
