Signature Generator

Draw or type your signature and download it as a transparent PNG. Free online signature maker — no email, no watermark, nothing uploaded.

A Signature You Can Reuse Anywhere — Created Privately

The Signature Generator produces a clean, transparent-background PNG of your signature, ready to insert into PDFs, Word documents, email footers, and design tools. Draw naturally with a mouse, trackpad, finger, or stylus — or type your name and pick a script typeface. The canvas renders at twice your screen's pixel density, so the exported image stays crisp when placed into documents.

Why Privacy Matters More Here Than Almost Anywhere

A signature is an identity artifact. Most "free signature maker" sites route your strokes through their servers and keep the result attached to the email address they demanded first — an odd thing to accept for something you would never hand a stranger on paper. Here the entire process runs in browser memory: no account, no upload, no stored copy. Close the tab and the signature exists only in the file you downloaded.

From PNG to Signed Document

The transparent PNG drops straight into Word (Insert → Picture), Google Docs, or any email client. To place it onto a PDF — positioned, resized, and flattened into the page — pair it with the Sign PDF tool, which is equally private and runs in the same browser tab.

Drawn vs. typed: which one to use, and when

A drawn signature is yours — unique motor patterns, natural variation, visually convincing on any document. Its weakness is hardware: a mouse produces a shakier line than the pen you have used your whole life. Two techniques close most of the gap: draw large (use the full canvas and let the export’s downscaling smooth the path), and draw fast — hesitant slow strokes wobble, confident quick ones look natural. On a phone or tablet, your finger or stylus makes this a non-issue.

A typed signature in a script font is the pragmatic alternative: instantly clean, perfectly repeatable, and entirely adequate for the places a signature is really a formality — email footers, internal approvals, newsletters. Its weakness is the opposite one: the same fonts are available to everyone, so it carries no identity. The honest rule: typed for decoration and flow, drawn for anything where the signature represents you.

Why the export is PNG and not JPG or SVG

JPG has no transparency — every JPG signature arrives inside a white rectangle that collides with shading, table borders, and dark themes. PNG’s alpha channel makes the background genuinely absent, and its lossless compression keeps stroke edges sharp where JPG’s block artifacts would fuzz them. SVG would in principle scale infinitely, but document tools (Word especially) handle embedded SVG inconsistently, and a 2×-resolution PNG survives every real-world insertion path. Practicality wins.

The workflow this tool anchors

The signature image is step one of a chain: Sign PDF places it onto contract pages with position and size control, the Invoice Generator gives freelance invoices a personal close, and for recurring use, keep the PNG in a notes app or password manager attachment — it is small, and regenerating an identical drawn signature is by definition impossible.

Key Concepts

Alpha Channel

The fourth value in an RGBA pixel controlling opacity. PNG supports a full 8-bit alpha channel, enabling smooth anti-aliased edges over any background — the reason signatures are exported as PNG rather than JPG, which has no transparency at all.

eIDAS

The EU regulation defining three tiers of electronic signature — simple, advanced, and qualified — with escalating identity and integrity requirements. A signature image is a "simple" e-signature under this framework.

Pointer Events

The unified browser input API covering mouse, touch, and stylus with pressure and tilt data — what lets one canvas signature pad work identically on a desktop, phone, or tablet with a pen.

Frequently Asked Questions

Is an image of my signature legally binding?

It can be, but the picture alone is not what makes it so. E-signature laws like the U.S. ESIGN Act and the EU's eIDAS regulation focus on intent to sign and consent to do business electronically — an inserted signature image satisfies many everyday consumer and business contexts, while regulated documents may require a qualified e-signature with identity verification and an audit trail. For those, use a dedicated signing platform; for everything else, a clean transparent PNG is exactly what's needed. (This is general information, not legal advice.)

Why does the transparent background matter?

A signature exported with a white box around it looks pasted-on the moment it lands on any non-white document — shaded contract fields, letterheads, dark-mode PDFs. The PNG alpha channel makes the background genuinely empty, so only the ink pixels overlay the document beneath, exactly like a real pen stroke on paper.

Where does my signature go after I draw it?

Nowhere. The canvas lives in your browser's memory, the PNG is assembled locally, and the download travels straight from that memory to your disk. There is no server round-trip, no account, and no gallery of user signatures — which is precisely the property you want in a tool handling something as identity-sensitive as your signature.

What size and resolution should a signature image be for documents?

Aim for the signature to occupy roughly 400–600 pixels of width at export and be placed at 150–250 px wide in the document — inserting large and scaling down keeps edges crisp in print. This tool exports at 2× the drawn size for exactly that headroom. In Word and Google Docs, drag the image to about 4–5 cm wide; in PDFs, match the signature line's width. If the result prints blurry, the image was drawn too small, not placed too small.

Should I worry about someone copying my signature image from a document?

Treat a signature image like letterhead: mild, real, manageable risk. Anyone with a signed paper document could always scan your signature — the image file only lowers that effort slightly. Sensible practice: use image signatures for low-stakes documents and internal paperwork, use audited e-signature platforms for contracts (their evidence trail, not the picture, is what carries legal weight), and never publish documents bearing your signature on the open web when a redacted version will do — the Redact PDF tool on this site exists for that.

Troubleshooting & Technical Tips

Drawn lines look jagged or pixelated

The canvas renders at 2× your screen's pixel density, so jaggedness usually means the signature was drawn very small and scaled up later. Draw large — use the full canvas width — and let the destination document scale it down; downscaling sharpens, upscaling blurs.

Typed signature shows a plain font instead of handwriting

The script fonts load with the page; on a very slow connection the canvas may render before they arrive. Wait for the font preview buttons to display in their actual styles, then re-select the font — the canvas re-renders with the loaded typeface.
