Business letter template on your own letterhead
A formal business letter has to look right: your letterhead at the top, the date and addresses in the correct places, clean margins, a tidy signature block. SlimDoc gives you a real A4 page to lay all of that out, with your logo set as a page background so it sits behind every page like printed stationery. It runs entirely in your browser, so the letter — and whoever it is addressed to — never leaves your device. No upload, no account, no watermark.
Why SlimDoc for business letter
Your letterhead, not a generic template
Add your company logo as a page background image so it anchors the top of every page like pre-printed stationery. Pair it with a header and footer for your address, phone, and registration line. They repeat on each page automatically.
Looks like a real printed letter
You edit on a true A4 page (210×297mm) with live pagination, so what you see is exactly what prints. Set page margins, pick a font, align the date and references, and the layout holds when you export.
The recipient never touches a server
Everything runs locally in the browser. A confidential letter to a client, lawyer, or candidate stays on your machine — nothing is uploaded. Save it as one self-contained .html file and reopen or reprint it any time, even offline.

How to make it
Set up your letterhead
Right-click the page to add a logo as the page background image, then add a header for your company name and address and a footer for the registration or contact line. Both repeat on every page.
Write the letter body
Type the date, recipient address, salutation, and body on the A4 page. Choose a font, set the line spacing, and use alignment to place the date and reference. Add a signature block at the bottom; pagination flows extra text to a clean second page.
Export to PDF and send
Switch to Preview to check the finished page, then use Print / Export to PDF. The logo, header, footer, and margins all resolve in the output. Save the .html file to reuse the letterhead next time.
Frequently asked
How do I add my company logo as a letterhead?
Right-click the page and set your logo image as the page background. It sits behind the text on every page, exactly like pre-printed letterhead stationery. You can also place a logo in the header if you prefer it inline with your address.
Will the letter print on a single, properly formatted A4 page?
Yes. SlimDoc edits on a true A4 page (210×297mm) with live pagination, so the layout you see is what prints. If the body runs long, it flows onto a clean second page and your header, footer, and logo repeat automatically.
Is my letter uploaded anywhere?
No. SlimDoc runs entirely in your browser. The letter and its contents never leave your device — there is no upload, no account, and it works offline. That matters for confidential correspondence to clients, candidates, or legal contacts.
Can I reuse the same letterhead for future letters?
Yes. Save the letter as a single self-contained .html file with the logo, header, footer, and fonts all included. Reopen it in SlimDoc, replace the date and body, and you have a reusable letterhead. You can also use {{placeholder}} tokens for fields you fill in each time.
What font should a formal business letter use?
SlimDoc includes 9 font families including Arial, Georgia, and Courier New. A serif like Georgia or a clean sans like Arial both read as formal. Set the size between roughly 11 and 12px-equivalent for the body and use justify or left alignment for the paragraphs.
How do I add page numbers or a footer to a multi-page letter?
Add a footer pinned to the page edge and insert a "Page X of Y" token. The footer and its page numbers repeat on every page, which is useful for longer letters or attached enclosures.
