Frequently Asked Questions (FAQ)

Q: What is an SVG signature and why should I use it?
A: SVG (Scalable Vector Graphics) signatures are vector-based, meaning they maintain perfect quality at any size—never pixelated or blurry. Unlike PNG/JPG images that lose quality when enlarged, SVG signatures stay crisp whether printed on business cards or large documents. You can download your SVG signature and reuse it across multiple platforms!
Q: Is this tool really free?
A: Yes! PDF Signature Pro is completely free with no hidden charges, subscriptions, or watermarks. It's an open-source tool built for everyone.
Q: Is my PDF secure? Where is it stored?
A: Your PDF is completely secure. All processing happens directly in your browser using JavaScript. Your files never leave your device and are not uploaded to any server. Once you close the browser tab, everything is deleted from memory.
Q: Can I download my drawn signature as an SVG file?
A: Absolutely! After drawing your signature, click the "Download SVG" button to save it as a vector file. You can then reuse this SVG signature in other documents, websites, or applications without any quality loss.
Q: What signature formats are supported?
A: You can draw signatures (automatically saved as SVG vectors), or upload existing signature files in PNG, JPG, JPEG, or SVG format. All formats maintain their original quality in the final PDF.
Q: Are the signatures legally binding?
A: Digital signatures created with this tool can be legally binding depending on your jurisdiction and document type. For high-security legal documents requiring certificate-based digital signatures, consult with a legal professional or use certified digital signature services.
Q: How is the SVG signature embedded in the PDF?
A: SVG signatures are converted to high-resolution PNG (2400x800 pixels) for PDF embedding, ensuring maximum quality and compatibility across all PDF readers. The conversion maintains the crisp appearance of the vector signature.
Q: Can I add multiple signatures to one PDF?
A: Currently, the tool supports adding one signature per session. To add multiple signatures, download the signed PDF and re-upload it to add another signature.
Q: What's the maximum PDF file size?
A: The tool works best with PDFs up to 50MB. Larger files may work but could be slower depending on your device's processing power and available memory.
Q: Can I use this on mobile devices?
A: Yes! The tool is fully responsive and works on smartphones and tablets. You can draw signatures using your finger or stylus, and drag/resize them with touch gestures.
Q: Does this work offline?
A: After the initial page load, most functionality works offline since processing happens in your browser. However, you need an internet connection to load the page and external libraries initially.
Q: How do I resize and move the signature?
A: After placing your signature, drag it anywhere on the PDF by clicking and holding. To resize, drag the circular blue handle at the bottom-right corner. The tool automatically enters fullscreen mode for easier positioning.
Q: What browsers are supported?
A: PDF Signature Pro works on all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the best experience, use the latest version of your browser.
