Frequently asked questions

How does this secure TSV to HTML converter protect my files?
All parsing and formatting happens entirely inside your browser's JavaScript engine. Your TSV data is never sent to a server, and no copy is retained after you close or refresh the tab, achieving true zero data retention.
Can I use this secure tool to convert confidential TSV data?
Yes. Because the TSV to HTML conversion runs client-side in an isolated Web Worker thread, even confidential or personally-identifiable TSV records never leave your device. It is suitable for HIPAA-sensitive datasets, financial records, and enterprise data governance workflows.
Does the secure TSV to HTML converter work without an internet connection?
Once the page has loaded, the conversion engine itself requires no active network connection. You can paste or drag a TSV file and produce a HTML output entirely offline after the initial page load.
Is there a file size limit for secure TSV to HTML conversions?
There is no server-enforced upload limit because no file is ever uploaded. Files up to 100 MB are supported in-browser. Performance scales with your machine's RAM; a background Web Worker keeps the UI responsive during heavy TSV parsing.
What encryption or security standard does the TSV to HTML conversion use?
The strongest protection is eliminating the transmission entirely. Because TSV processing never crosses a network boundary, there is no attack surface at the transport layer. All computation is sandboxed inside the browser's origin-isolated context.
