Build an email signature
Your signature goes out with every message you send, so it is the worst place for anything that can break. This builds the plain version that looks the same everywhere.
- Runs entirely in your browser

How it works
- Fill in the fields you want — leave the rest empty and they disappear.
- Choose the Japanese or Western order and an accent colour.
- Press “Copy as formatted signature” and paste it into your mail client’s signature box.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
Why no logo image?
Because a logo in a signature is a picture loaded from the internet on every message you send. Most mail programs block such pictures by default, so many recipients see a broken-image box instead of your logo. It makes each message heavier, some programs turn it into an attachment so every reply shows a paperclip, and some spam filters treat it like a tracking pixel. A text signature always displays.
Why tables in 2026?
Because the classic Outlook on Windows — still the standard in a large share of Japanese offices — displays mail with the Word engine, not a web browser, and Word does not understand modern web layout (flexbox, grid). Tables are not nostalgia here; they are the layout that survives everywhere, including that program. (The newer Outlook is moving to a web engine, but the old one is not going away soon.)
What is different about the Japanese order?
Company and department come before the person, the postal code is written with 〒 before the address, and phone numbers are labelled TEL and FAX. The Western order puts the person first with the job title beside the name. Both are provided because sending the wrong one reads as carelessness to the recipient.
Will the copy button keep the formatting?
Yes — it puts both an HTML and a plain-text version on the clipboard, so pasting into a signature editor keeps the layout and pasting into a plain-text field gives readable text. If your mail program only accepts HTML code, the code is shown below the preview.
