Quick answer. Fill in your name (and any optional details), copy the signature, and paste the preview into Gmail or Outlook — not the HTML tags. For a logo that recipients will actually see, use a public image URL, or add the image inside Gmail or Outlook after you paste.
How to create and copy your signature
Type your name, then add a role, shop name and contact lines if you want them. A name-only signature is fine. Choose a layout, a common email font (Arial, Georgia, Calibri, Times New Roman or Verdana) and an accent colour for your name and links. Copy the signature, paste it into Gmail or Outlook as in the official steps below, and save. Details you enter can be remembered in this browser so the next visit is quicker; use Clear saved details to wipe them. A logo file is never stored.
How to add this signature in Gmail and Outlook
Paste the preview, not the HTML tags. Pasting source code will show the tags as text in the signature box. Official menu labels, from help pages read on 12 November 2026:
- Gmail (computer): Settings → See all settings → Signature → paste into the signature box → Save Changes. Official article: Create a Gmail signature.
- Outlook (new Outlook, Outlook on the web, or Outlook.com): Settings → Accounts → Signatures → paste into the editing box → Save. Official article: Add and change an email signature in Outlook.
- Classic Outlook for Windows: New Email → Signature → Signatures → paste into Edit signature, or follow Microsoft’s path of pasting into a message and then copying into Signatures, in Create an Outlook signature block with a photo and links.
Copy HTML is only for a client or CMS field that accepts HTML source. Gmail and Outlook signature boxes want Copy signature.
Logos, image URLs and file size
This site does not host images. The reliable path is a public https URL of a logo that is already on the web. The HTML then uses a normal <img src="https://…">, which matches Gmail’s official “Web Address (URL) — Enter the URL of an image that is publicly available on the web” method (Troubleshoot issues with Gmail signatures, read 12 November 2026). A Google Drive image only works if sharing is set so anyone with the link can view; if the file is later deleted, Gmail’s help says the image will not show.
If you choose a file on this page, it is previewed locally and, if you still copy HTML from here, embedded as a data URI (a long data:image/…;base64,… string). That is not a publicly hosted web address. Gmail’s official image methods are a URL, a public Drive file, or an upload inside Gmail. A data URI is large and can hit Gmail’s official 10,000-character signature limit — “Your image also counts toward the character limit” — or trigger Gmail’s “try to resize the image” error. Many email clients also do not display data-URI images reliably. The recommended workaround: copy the signature without the file embed (or with a URL if you have one), then add the logo inside Gmail or Outlook, or host the logo yourself and paste the URL here.
Gmail’s official size guidance (same troubleshooting article): recommended 70–100 pixels high by 300–400 pixels wide; maximum 100 pixels high by 1000 pixels wide. The default preview follows that recommended height. A much taller local file is resized here and flagged. Use the Image Resizer to get a logo into that size first. Outlook’s photo-and-links article accepts .bmp, .gif, .jpg or .png for signature images; those are the types this page accepts. The HTML is a simple table with inline styles and a normal image — no VML, no scripts, no tracking pixels and no web fonts. A plain-text fallback (name, title, contact lines) goes on the clipboard with the rich signature.
For sellers and small shops
Use the same shop name and contact details you put on invoices, so customers see one letterhead. The Invoice Generator builds the PDF in your browser too. The Favicon Generator can make a small shop icon from a logo. To sign a PDF contract or packing slip, use Sign PDF — that is a different job from an email footer, and this page is not a legally binding electronic signature.
Privacy
The signature is built in this browser. The logo is not uploaded to DailyToolLab. Saved details stay only in this browser until you clear them, and a chosen logo file is never written to storage. Microsoft Clarity does not record this page.
Frequently asked questions
Is this email signature generator free?

Do I need to sign up?
No. Open the page and start typing.
Does this work in Gmail?
Yes. Copy the signature (the preview, not the HTML tags) and paste it into the signature box in Gmail Settings, then save. Official steps: https://support.google.com/mail/answer/8395
Does this work in Outlook?
Yes. Paste the copied signature into the signature editor in new Outlook, Outlook on the web, or classic Outlook, then save. Official steps: https://support.microsoft.com/en-us/outlook/mail/how-to-add-and-change-an-email-signature-in-outlook
Why should I use a logo URL instead of uploading a file here?
DailyToolLab does not host images. A public URL is what Gmail’s “Web Address” option expects. A file chosen here can only be embedded as a data URI, which is large (Gmail’s signature limit is 10,000 characters, and images count toward it) and often unreliable in inboxes. You can also add the logo inside Gmail or Outlook after you paste.
What size should my signature image be?
Gmail recommends 70–100 pixels high by 300–400 pixels wide, and sets a maximum of 100 pixels high by 1000 pixels wide. Resize the logo first if it is larger.
Is my information uploaded?
No. The signature is built in your browser. If you save your details, they stay only in this browser until you clear them.
Is this a legal electronic signature?
No. This tool makes an email footer. To draw or type a signature on a PDF, use Sign PDF.
