Frequently asked questions

Is it safe to use Escape Tool with sensitive or confidential data?
Yes, completely. All processing done by Escape Tool runs 100% client-side inside your local web browser using a background Web Worker thread. Your data is never uploaded, transmitted, or stored on any server, not even temporarily.
What is the maximum file size Escape Tool can handle?
Escape Tool supports files up to 100 MB. Because all parsing happens inside your browser's memory rather than on a server, performance scales with your computer's available RAM. The Web Worker architecture keeps the UI fully responsive even during heavy processing.
How does Escape Tool process my data without uploading it?
Escape Tool uses modern browser File and Blob APIs alongside battle-tested open-source libraries (such as PapaParse and SheetJS) bundled directly into the page. When you load a file or paste data, the browser reads it into local memory and the conversion runs entirely inside a sandboxed Web Worker thread. No network call is ever made.
Do I need to install anything to use Escape Tool?
No installation, browser extension, or plugin is required. Escape Tool runs as a standard web page inside any modern browser. Simply open it, load your data, and download the output. Nothing to install and nothing to uninstall.
Does Escape Tool work offline after the page has loaded?
Yes. Once Escape Tool has finished loading in your browser, the conversion engine itself requires no active internet connection. You can disconnect from the network and continue converting files; all processing stays fully on-device.
