Frequently Asked Questions
Everything you need to know about PDFMiniFly’s local-first architecture.
Can I safely process confidential bank statements or contracts?
Yes. Because supported tools in PDFMiniFly process documents directly within your browser's local sandbox, your documents are edited on your machine. You can inspect your browser’s Network tab to confirm that no document bytes are transmitted during local tool execution.
How does the PWA / offline mode work?
You can click the Install App button in the navigation bar to add PDFMiniFly to your desktop dock or phone home screen. Once installed, service workers cache the application shell and core local processing modules, allowing you to edit PDFs even without internet access.
Are there limits on file sizes?
PDFMiniFly enforces no artificial paywall limits. The only constraint is your device’s available memory (RAM). For large files (>100MB), the app will display a gentle advisory so your browser tab remains responsive.
