How Client-Side Processing Works Behind the Scenes
Unlike traditional cloud utilities, ReadyForFile executes all file processing directly within your device’s browser sandbox:
The browser loads your document into local device RAM via the HTML5 File & FileReader API.
High-performance JavaScript / WebAssembly compiles the output locally without transmitting network packets.
The generated output is packaged into a local blob: URI and saved directly to your filesystem.

Frequently Asked Questions
Do the generated QR codes ever expire?
No! All QR codes generated on ReadyForFile are static QR codes that encode your data directly into the pattern. They will work forever and never expire.
Is there any scan limit on created QR codes?
No. Since the QR codes are static, there are zero scanning limits, zero subscriptions, and zero tracking redirects.
Can I add my business logo to the center of the QR code?
Yes! Upload your PNG, JPG, or SVG logo in the customization panel. High Error Correction Level is automatically applied when using a center logo to guarantee 100% scannability.
How do Wi-Fi QR codes work?
When a guest scans your Wi-Fi QR code with their iPhone or Android camera, their phone automatically prompts them to join the Wi-Fi network without typing the password.
