Write a polished cover letter, privately
A cover letter has to look right on one A4 page and read like it was written for this one job. SlimDoc gives you a real page to work on — proper margins, your own letterhead, the font you want — and exports a clean PDF straight from the browser. It runs entirely on your device, so your name, address, and salary expectations are never uploaded anywhere.
Why SlimDoc for cover letter
It stays on one page
You write on a true A4 page, not an endless scroll. Live pagination shows exactly where the page ends, so you can trim a sentence instead of guessing — and tighten margins with a margin preset if you need a little more room.
A letterhead that matches your CV
Add a header pinned to the top of the page for your name and contact details, with its own padding and background. Pick from nine fonts and set the size so the letter and your resume look like one application, not two.
Your details never leave your device
There is no upload, no account, and no sign-up. SlimDoc is a local-first editor — your address, phone number, and the company you are applying to all stay in your browser. It even works offline.

- Nine font families and adjustable font size to match your resume
- {{company}} and {{role}} placeholders to reuse one letter across applications
- One-click Print / Export to PDF via the browser's native print dialog
- Saves a self-contained .html file that re-opens straight back into the editor
How to make it
Set up the page and letterhead
Open the editor and add a header for your name, email, and phone. Choose a font and a margin preset. Type the date, the hiring manager's details, and your greeting on the A4 page below.
Write with reusable placeholders
Draft your letter once, then drop in {{company}} and {{role}} tokens wherever you name the employer or position. To send it to a new job, change just those two values. SlimDoc warns you if a token would collide with a reserved page-number token.
Preview and export to PDF
Switch to Preview to check the finished page, then use Print / Export to PDF. The output is print-perfect, with your letterhead and margins intact. Save the .html file too so you can re-open and tweak the letter later.
Frequently asked
Is my cover letter uploaded to a server?
No. SlimDoc runs entirely in your browser. Your letter, your contact details, and the company you are applying to never leave your device — there is no upload and no account. It works offline.
Can I export my cover letter as a PDF?
Yes. Use Print / Export to PDF and the browser's native print dialog produces a faithful, print-perfect PDF, including your letterhead, margins, and fonts. There is no watermark.
How do I reuse the same letter for different jobs?
Write the letter once and use {{company}} and {{role}} placeholders where you mention the employer and position. For each new application, change only those two values. SlimDoc highlights a warning if a placeholder would clash with the built-in page-number tokens.
Will my cover letter fit on one page?
SlimDoc uses true A4 pages with live pagination, so you see exactly where the page ends as you type. If you are slightly over, trim a sentence or switch to a narrower margin preset to keep it to a single page.
Can I make the cover letter match my resume?
Yes. Choose from nine font families, set the font size, and add a letterhead header with your name and contact details. Use the same font and header style as your CV so the two documents read as one application.
Is it really free, with no sign-up?
Yes. SlimDoc is free, with no account, no sign-up, and no watermark on your exported PDF. Your letter saves as a single self-contained .html file that opens and prints in any browser and re-opens right back into the editor.
