Frequently asked questions

Is it safe to use Phone Extractor with sensitive or confidential data?
Yes, completely. All processing done by Phone Extractor 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 Phone Extractor can handle?
Phone Extractor 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 Phone Extractor process my data without uploading it?
Phone Extractor 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 Phone Extractor?
No installation, browser extension, or plugin is required. Phone Extractor 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 Phone Extractor work offline after the page has loaded?
Yes. Once Phone Extractor 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.
