A letterhead is a clean, printable business-letter header you build in your browser and download locally; the Letterhead Generator produces exactly that as a single vector SVG file. The generator draws a white page, a horizontal accent rule under the company name, right-aligned contact lines, and a small footer with the company and website, leaving the rest of the page blank for the actual message. Every string you type is XML-escaped before it goes into the file, so ampersands, angle brackets, quotes, and apostrophes display as plain text and cannot become SVG elements. The output is a vector file, not a bitmap, which means you can scale the letterhead in your editor or print pipeline without losing sharpness, and the preview on screen shows the exact SVG string the Download SVG button will save. All generation runs in the current browser tab, so company information is not uploaded, stored in an account, or sent to a remote rendering service, and the download is created only after a direct click.
What the Letterhead Generator Produces
The Letterhead Generator outputs a single, self-contained vector SVG file. SVG is the format used for scalable graphics on the web, and because every line, rule, and label in this letterhead is drawn as vector geometry rather than a raster image, you can scale it to fit your page without losing sharpness. The file holds a white page area, a horizontal accent rule under the company name, right-aligned contact lines, and a small footer that repeats the company and website when available. There is no embedded logo, signature, QR code, tracking pixel, remote font, or external asset, so the file stays small, renders predictably across editors, and works without an internet connection after download.
The canvas uses a fixed 816 by 1056 logical viewBox with matching width and height attributes. Those numbers describe a portrait-shaped drawing surface in vector coordinates; they are not a guaranteed inch, millimeter, DPI, or paper-size value. When you open the SVG in a vector editor, word processor, layout application, PDF converter, or printer, the downstream application does the actual sizing. That is why it pays to check printer scaling, page setup, and margins after you download the file rather than trust the canvas numbers as physical dimensions or a calibrated paper size.
Because the same SVG string is shown in the preview and saved by Download SVG, what you see on screen is exactly what you get in the file. The browser trims surrounding whitespace, rejects disallowed control characters, XML-escapes ampersands, angle brackets, quotes, and apostrophes, and refuses a fourth non-empty address line rather than silently hiding content past the visible header. Other foreground and background colors stay neutral so the output remains readable regardless of the accent you choose.
Fields, Limits, and What Each One Controls
Every field has a defined boundary so the layout stays predictable and the generator can reject bad input instead of silently hiding it. The company name is the only required field; everything else is optional and skipped when left blank, so no fake content reserves space in the header. These limits are layout and performance boundaries for the tool, not official formatting rules for any particular paper standard.
| Field | Required | Limit | Where it appears |
|---|---|---|---|
| Company name | Yes | 80 characters | Upper left of the header and again in the footer |
| Tagline | No | Explicit character limit | Directly below the company name in the header |
| Address lines | No | Up to 3 non-empty lines | Top of the right-aligned contact block |
| Phone | No | Explicit character limit | Right-aligned contact block |
| No | Explicit character limit | Right-aligned contact block | |
| Website | No | Explicit character limit | Right-aligned contact block and footer |
| Accent color | Color picker required | 6-digit hex in #RRGGBB form | Horizontal header rule and footer divider |
The accent color is the one design choice you control directly. The browser color input supplies a #RRGGBB value, and the validator checks the format again before any SVG is generated, so partial values like three-digit shorthand or named colors get rejected. Header text, body area, contact text, and the page background use fixed neutral design colors, which is why the tool does not calculate brand contrast compliance or claim that any single accent satisfies your organization's accessibility policy. If your brand guide calls for a specific palette, choose the closest #RRGGBB value you can and verify the contrast yourself before sending the letterhead out.
How to Create the Letterhead Step by Step
- Open the Letterhead Generator in your browser and type your company name in the first field. The company name is required and capped at 80 characters, so keep it close to your registered or trading name rather than a long descriptive phrase.
- Add an optional tagline directly below the company name if you use one in your communications. Leave it blank if you do not have a tagline; the header adjusts without reserving fake space or showing placeholder text.
- Fill in up to three address lines, one piece of information per line. The generator rejects a fourth non-empty line rather than silently dropping it, so trim your address to three lines if it is longer and combine street and suite on a single line where it still reads naturally.
- Add the phone, email, and website you want shown on the letterhead. Each has its own character limit, and blank fields are skipped in both the header and footer, so you only need to enter what you actually want displayed on every letter.
- Pick an accent color using the browser color picker or by entering a six-digit hex value in #RRGGBB form. The accent appears in the horizontal rule under the company name and the matching divider in the footer; other design colors stay neutral and cannot be customized in this tool.
- Select Generate letterhead and read the preview carefully. The preview shows the exact SVG that the Download SVG button will save, so every visible detail in the preview carries over to the exported file including whitespace, alignment, and text order.
- Inspect the spelling, line wrapping, contact accuracy, accent contrast, and overall spacing in the preview. If anything is off, edit the field and the previous preview clears so the old download cannot appear to represent your new inputs.
- Click Download SVG, place the file in your document workflow, and verify printer scaling, page setup, margins, brand permission, and accessibility considerations before you send or print anything that carries the letterhead.
Editing any field clears the previous preview and revokes its temporary object URL, so a stale download cannot quietly survive a change to the inputs. The download URL is also revoked after use and when the component unmounts, which keeps the file in your hands rather than lingering as a cached resource. All generation happens in the current browser tab; nothing is uploaded, stored in an account, or sent to a remote rendering service, and the file name is derived from a sanitized version of the company name you typed.
What to Verify Before Printing or Sending
A clean header is only half the job. Before you put the letterhead in front of a customer, supplier, or regulator, walk through a few checks that the generator cannot do for you. The tool's contract is narrow: validate bounded text and one color, escape every string for XML, serialize one deterministic SVG, show that exact string in the preview, create a local download only after direct action, and distinguish logical canvas dimensions from physical print claims. Everything outside that contract is your responsibility.
- Confirm spelling and punctuation for the company name, tagline, address, phone, email, and website. The preview mirrors the SVG, but a missing comma, stray space, or transposed digit will travel with the file into every document you create from it.
- Check the line wrapping and contact order. The right-aligned contact block renders in the fixed order address, phone, email, and website, so rearranging means changing the fields themselves, not the layout.
- Evaluate the accent color against your brand guide and against any accessibility guidance your organization follows. The tool does not audit contrast or assert that a chosen accent meets a specific policy, so a quick visual check on the preview is worth doing before you commit.
- Verify that you have brand permission to use the company name and any phrasing in the header. A polished letterhead does not prove that the named organization exists or that you are authorized to send correspondence on its behalf.
- Open the SVG in the editor, word processor, or PDF converter you plan to use, and confirm that the page setup, margins, and scaling produce the physical size you expect. The 816 by 1056 viewBox is a logical canvas, not a calibrated paper size, and physical output depends on the downstream application's page setup and hardware.
- Review the body area the letterhead leaves blank. The page is intentionally empty below the header so you can write the message in the same vector editor or paste in content from your usual workflow without overlapping the contact details.

Creating a letterhead is realistic when the tool gives you validated input, a deterministic SVG output, and a preview that matches the file. The Letterhead Generator keeps the contract narrow: bounded text, one color, escaped strings, one SVG, local download. The rest of the work, including proofreading, brand permission, accessibility review, and physical page setup, stays with you, which is exactly where it belongs.
