Frequently Asked Questions (FAQ)

Is this an electronic signature or digital certificate?

This tool creates a visual electronic signature (ISO 32000-1) by placing your handwritten, typed, or stamped signature directly onto the document. It does not generate cryptographic PKI digital certificate seals.

Are my confidential PDF documents uploaded to any server?

No. All signature drawing, vector embedding, and PDF compiling execute 100% locally in your browser. Your sensitive contracts, signatures, and personal details never leave your computer.

Does signing a PDF reduce text or image quality?

No. Our engine embeds high-resolution PNG vectors natively onto the existing PDF pages without rasterizing or flattening the background document. Selectable text and sharp vectors remain 100% intact.

Can I sign multiple pages in the same PDF?

Yes! Use the left thumbnails sidebar to navigate between pages. You can place signatures, initials, dates, and checkmarks on any page or duplicate signatures across pages.

How does white background removal work on uploaded signatures?

When you upload a signature photo on white paper, our automatic background filter detects and removes white/light pixels, creating a clean transparent signature that blends seamlessly over document lines.

Can I change the signature ink color?

Yes. You can choose between standard Black, Navy/Dark Blue, or Red ink colors when drawing or typing your signature.

Does the tool work on smartphones and tablets?

Yes. The drawing canvas supports touch events and stylus pens with pressure sensitivity on iPads, Android tablets, and iPhones without installing software.

What is the Signing Audit Report?

It is a downloadable text file detailing the exact pages signed, number of visual signature objects placed, coordinates, file size, and timestamp for your compliance records.

How does the in-memory verification test work?

After compiling the signed document, the engine reopens the output PDF in memory and renders all signed pages with PDF.js to verify that zero rendering faults occurred.

Is there any fee or watermark added to my signed PDF?

No. IMGFixy Sign PDF is 100% free with unlimited document signing and zero watermarks.
