Sign PDF FAQ
Is an image-based signature legally valid?
In most jurisdictions, an image of your signature on a PDF is legally acceptable for everyday business documents. For high-security legal documents, a cryptographic digital signature may be required.
How do I create a signature image?
Sign your name on white paper, take a photo with your phone, and upload it. Our tool automatically removes the white background to give you a clean, transparent signature overlay.
Can I sign multiple pages?
Yes! You can navigate between pages and place your signature on any or all pages of a multi-page PDF document. Each page can have a signature in a different position.
What file formats are supported for signatures?
You can upload signature images in JPG, PNG, or WebP format. PNG images with transparent backgrounds work best, but our tool can process any format.
Does my signed PDF retain the original quality?
Yes. The original PDF content is preserved, and your signature is overlaid on top. The output maintains the same resolution and formatting as the original document.
Is this tool free?
Yes, completely free with no limits. Sign as many PDFs as you want, with no watermarks, no registration, and no premium features locked behind a paywall.
