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
How precise is the audio cutter?
The audio cutter allows precision down to 0.1 seconds (100 milliseconds) using the fine-tuning nudge buttons and waveform display.
Is my audio file uploaded to any cloud server?
No! All audio slicing, fading, and exporting run 100% locally in your web browser using HTML5 Web Audio APIs. Your files remain 100% private.
What is the difference between 'Keep Selected' and 'Remove Selected'?
'Keep Selected' exports only the region between your start and end points. 'Remove Selected' cuts out that section and stitches the rest of the audio together.
