Will it behave the same on every attorney’s machine?

Yes. The lock is standard .docx header behavior — part of the format, not an add-in — so the file works identically in Word 2016 and newer on Windows and Mac, including the office machine that hasn’t been updated in years.

We added a named partner. What does updating cost?

Have the designer update the artwork, then rebuild the Word file from the new PDF — two minutes and $9, same as the first time. No subscription, no per-seat licensing, no waiting on a freelancer’s queue.

Can we get it on Legal-size paper?

Yes — Letter, Legal, A4, and custom sizes are all included. The typing area you drag becomes the margins for the size you pick, so pleadings-adjacent documents and standard letters can each get their own file.

Is a confidential letter safe to type on this file?

The letter never touches our servers — it’s typed in your copy of Word, in your file. WordLetterhead only ever sees the letterhead artwork itself, and only if you buy the clean file; the sample doesn’t upload anything at all.

Law Firm Letterhead in Word: Locked, Every Page, No Rebuilds

The firm’s letterhead exists — as the print PDF from the rebrand or the new named partner. The letters go out in Word. Here’s how firms bridge that gap without a designer on retainer and without the shared file that keeps breaking.

Why does the firm’s Word letterhead keep getting wrecked?

Because the artwork is reachable. In most hand-built files the design sits in the editable layer, so every engagement letter, demand letter, and representation letter is a chance for someone to nudge the logo or delete the footer — then the mangled version gets saved over the good one and multiplies. The fix is structural: artwork in the header layer can’t be selected at all while anyone types.

Does the letterhead file leave the firm’s hands?

Not here. The sample renders locally in your browser — the letterhead file isn’t uploaded. Paying sends up only the rendered artwork; the .docx is assembled in memory, streamed back, and never stored. No account, either. Compare that with emailing the brand package to a freelancer, or feeding it to a free converter site with unknown retention.

How does a firm set this up?

Once, in about two minutes, from the file the designer already delivered. WordLetterhead turns the PDF (or PNG or JPG) into a .docx with the design locked in the header at 300 DPI, on Letter or Legal:

Upload the letterhead the firm already has.
Drag the typing area where letters should sit — it becomes the margins.
Download the .docx and circulate it as the firm’s letter file.

The design repeats on every page, prints at full strength by default, and the standard first-page-only layout is already configured. Opening a new firm? The launch-list version is here.
