Questions & Answers

Common Questions

Find quick answers about how PDFVision works and keeps your files safe.

Is the signature background transparent?

Yes. The canvas has no background fill, so only your ink strokes are captured and embedded — no white box.

Can I choose any position?

Yes. After drawing your signature, you will see a live preview of your PDF with the signature you can drag anywhere on the page.

How to sign PDF files securely online

Traditional e-signature services often require you to upload your sensitive contracts to their servers, where your data is stored and managed by a third party. PDFVision takes a different approach. Our Sign PDF tool uses client-side technologies to ensure that your signature and your documents never leave your browser.

By performing the signature embedding locally, you maintain total control over your information, making it the most private way to sign legal agreements, NDAs, and business proposals online.

The importance of transparent signatures

A common problem with many PDF signers is the "white box" effect, where a signature has a solid background that obscures the text underneath. PDFVision's signature pad captures your strokes with a transparent background.

When you embed your signature into a PDF using our tool, only the ink is placed on the document. This results in a professional, authentic look that integrates seamlessly with the existing layout of your file.

Why local PDF signing is more professional

Beyond security, local signing offers several professional advantages:

High Precision: Drag and drop your signature exactly where the line is.
Responsive Design: Sign on your desktop, tablet, or smartphone with ease.
Permanent Embedding: We use industry-standard PDF libraries to inject the signature data directly into the file structure.
Privacy Verification: You can verify that no network requests are made with your document content.

Placing your signature with precision

Our tool provides a live, interactive preview of your document. After drawing your signature, you can navigate to any page and drag the signature to the precise location required. You can even adjust its size using the slider to ensure it fits perfectly within the signature block of your document.
