Signature Generator

As a rule of thumb, a signature about 1000 pixels wide prints crisply at roughly 8 cm (3 inches). Exporting larger than you need adds file size, not detail.

PNG or SVG? The PNG is a pixel image at the size you picked and works everywhere. The SVG is a vector file built from the actual stroke paths you drew, so it stays perfectly sharp at any size and can be recoloured or edited in Illustrator, Inkscape or Figma — useful if the signature will be engraved, embroidered or printed very large.

How to add the signature to a document

Microsoft Word

Insert → Pictures → This Device, choose the PNG, then set Wrap Text to In Front of Text. You can now drag the signature onto the signature line and resize it from a corner handle. Because the background is transparent, the printed line stays visible under the ink.

PDF

Most PDF editors offer an image stamp or "Add image" annotation. Place the PNG over the signature field and scale it down until the ink height matches the surrounding text.

Google Docs

Insert → Image → Upload from computer, then choose the Wrap text or Behind text option so the signature can be positioned freely.

Email signature

Use the 1× export and keep the image under roughly 300 pixels wide. Remember that some email clients block images by default, so never rely on the signature image alone to carry your contact details.

Tips for a signature that looks real

• Sign large, export trimmed. Use the full width of the pad — big movements are smoother than cramped ones, and the export is cropped to the ink anyway.
• Move quickly. Drawing slowly produces a wobbly line. One confident sweep beats a careful trace every time.
• Do not aim for perfection. Real signatures are inconsistent. If it takes ten tries to get a "perfect" one, it no longer looks like a signature.
• Use a stylus or your finger on a phone or tablet if you have one — touch input records far more detail than a mouse.
• Check it on dark. Flip the pad background to Dark before exporting. If a pale halo appears around the ink, thicken the stroke slightly and export at 2×.
• Keep it modest in size inside documents. A signature much taller than the surrounding text reads as pasted-in.

Are electronic signatures legally valid?

In most places an electronic signature carries legal weight. The ESIGN Act and UETA in the United States, eIDAS in the European Union, and comparable statutes in the United Kingdom, Canada, Australia and India generally recognise a signature applied with the intent to sign. What the law cares about is intent, consent, and being able to show who signed and what they agreed to — not the file format.

Some documents are still excluded almost everywhere: wills and testamentary trusts, many property deeds, adoption and divorce paperwork, court filings, and notices such as utility shut-offs or foreclosure. High-value or regulated agreements may also require a qualified electronic signature backed by an identity certificate, which an image cannot provide. When in doubt, check your local rules or ask a lawyer.

Frequently Asked Questions

How do I create a signature with a transparent background?

Draw your signature in the pad or type your name, then click Download PNG. The exported file is a PNG whose background pixels have an alpha value of zero, so only the ink is visible. Placed on a contract, a letterhead or a dark slide, the signature shows no white box around it. A JPG cannot do this because the JPG format has no alpha channel.

Is the signature generator free?

Yes. Drawing or typing your signature, downloading it as a transparent PNG and copying it are free. The SVG vector export, which stays sharp at any size for print and design work, is part of a membership.

Is my signature uploaded to a server?

No. The signature is drawn on an HTML canvas element and exported by your own browser using the canvas toDataURL and toBlob methods. No stroke data, image or name is ever sent to miniwebtool or anywhere else, and nothing is stored after you close the page.

What size should I export my signature at?

For email footers, web pages and on-screen documents, 1× is enough. For a PDF or a Word document that will be printed, choose 2× or 4× so the signature stays crisp at 300 DPI. A signature roughly 1000 pixels wide prints cleanly at about 8 centimetres. Exporting larger than you need only makes the file bigger, it does not add detail.

Why does my drawn signature look thick and thin in places?

That is deliberate. The pen measures how fast you move and makes fast strokes thinner and slow strokes thicker, imitating the pressure a real pen puts on paper. It is what stops a mouse-drawn signature from looking like a flat, uniform line. Choose the Ballpoint pen if you prefer an even stroke width, or the Marker pen for a constant thick line.

Is an electronic signature made with this tool legally valid?

In many jurisdictions an electronic signature is legally recognised. The United States ESIGN Act and UETA, the EU eIDAS regulation and similar laws elsewhere generally accept a signature applied with the intent to sign. What matters legally is intent, consent and a record of who signed, not the file format. Some documents, such as wills, deeds and certain court filings, still require a handwritten or notarised signature. Check your local rules for high-value or regulated documents.

Can I use a typed signature instead of drawing one?

Yes. Switch to the Type tab, enter your name and pick one of the five handwriting styles. The typed signature is rendered with a small amount of natural variation in the position and angle of each letter so it does not look mechanically perfect. The styles use the handwriting fonts already installed on your device, so the exact look varies a little between Windows, macOS, Android and iOS.
