Electronic Signature Online Free

Draw and download your signature instantly — 100% private, no uploads required.

Why Use QuickPDFify to Create Signatures?

Most online signature tools require you to upload documents to a remote server, exposing sensitive information. QuickPDFify processes everything locally on a canvas in your browser — your signature data never leaves your device. Draw naturally with your mouse or touchscreen, choose from Black, Blue, or Red ink, adjust stroke thickness from 1 to 8 pixels, undo individual strokes, and download your signature as a transparent PNG. 100% private, always free.

Draw Naturally

Use your mouse, trackpad, or touchscreen to draw your signature just as you would with a pen. Smooth stroke rendering for a natural feel.

Choose Ink Color

Select from Black, Blue, or Red ink colors to match your document style. The canvas updates instantly with your selected color.

Adjust Thickness

Fine-tune your stroke width from 1 px (fine tip) to 8 px (broad stroke). Find the perfect weight for your signature style.

Transparent PNG

Download your signature with a transparent background, ready to insert into any document, PDF, or form without messy white boxes.

Use Cases

The QuickPDFify signature creator is perfect for: signing digital documents and contracts, adding handwritten-style signatures to PDFs before sharing, creating signature images for online forms, placing a signature in email footers, stamping approval on internal documents, and generating quick sign-offs for personal use. No paper, no scanner — just your device and a few clicks.

How It Works

Draw — Use your mouse, touchscreen, or stylus to draw your signature on the canvas. The stroke appears in real-time with your chosen color and thickness.
Customize — Switch between Black, Blue, or Red ink using the color buttons. Adjust the stroke thickness slider (1–8 px) to get the perfect weight.
Undo — Made a mistake? Press the Undo button to remove the last stroke without clearing the entire canvas. Keep undoing until it is just right.
Download — Click the download button to save your signature as a transparent PNG image. It is immediately ready to insert into any document.

What formats are supported?

Signatures are downloaded as PNG images with a transparent background. This format works universally across documents, PDFs, forms, and image editors.

Can I change the signature color?

Yes. Three ink colors are available — Black, Blue, and Red. Simply tap or click the color button to switch. The next stroke you draw will use the active color.
