About the Remove Email Addresses

Sharing a support thread, a log file or a spreadsheet export usually means removing the email addresses in it first. Doing that by hand is slow and easy to get wrong, and the one you miss is the one that matters.

This tool finds every email address in a text and removes, masks or replaces it. Full redaction takes the address out entirely. Masking keeps the shape — j••••@example.com — which is enough to tell two people apart in a thread without exposing either. Domain-only mode keeps the company but drops the person, which is often exactly the right amount of detail for an analysis. Nothing is uploaded, which matters more here than on most tools.

Key features of the Remove Email Addresses

Three levels of redaction

Remove entirely, mask the local part, or keep only the domain — enough detail for analysis without exposing anyone.

Masking keeps people distinguishable

j•••••@example.com still tells two participants in a thread apart, which full removal does not.

Obfuscated forms caught

"name at example dot com" and the bracketed variants are matched, since those are how addresses get written to dodge scrapers.

mailto links handled

Both the visible text and the address inside the href are treated, so nothing survives in the markup.

Nothing is uploaded

The document never leaves your device, which is the whole point when the reason you are here is confidentiality.

Frequently asked questions

The processing itself is: everything happens in your browser and nothing is uploaded or stored. Always read the result before sharing, though — no pattern match is a substitute for a human check on a sensitive document.
