Frequently Asked Questions
Do I need to download any compress PDF app?
No. Our tool works entirely in your browser. No software, no app store, no installation. Just open the website and compress.
Will this work on my iPhone / Android phone?
Yes. The tool is fully mobile‑responsive. Works on Safari, Chrome, Firefox, and any modern browser. You can even add it to your home screen as a PWA.
Is it really free? No in‑app purchases?
Completely free. No hidden fees, no premium upsell, no “pay to compress larger files”. We believe PDF compression should be free for everyone.
How is this better than an app from Google Play or App Store?
Apps often request intrusive permissions, show ads, or limit compressions. Our web tool requires zero permissions, has no ads, and works instantly on any platform – even on computers where you can't install apps.
Can I compress PDFs offline?
After the page loads once, you can use it offline (basic compression) because it's a Progressive Web App. But for best results, an internet connection is recommended.
What about file privacy? Do apps store my PDFs?
Many free apps upload your PDFs to their servers without encryption. We use SSL encryption and auto‑delete after 2 hours. Your files never stay on our servers – more private than most apps.
