Questions people ask
Is this signature legally valid?
It is a simple electronic signature, which many offices accept. Where a certified Digital Signature Certificate (DSC) or Aadhaar eSign is required by law, use those instead.
Can I use a photo of my signature on paper?
Yes. We remove the white paper so only the ink is placed on the PDF.
Is Sign PDF really free?
Yes. Every PDFtoOne tool is free with no login, no daily limit and no watermark. The site is supported by ads.
Is there a file size limit?
We set no limit. Files are processed by your own device, so the only limit is its memory. Computers handle very large files; phones handle most everyday files easily.
Does it work offline?
Yes. Once you have used a tool, it keeps working without internet. You can also install PDFtoOne as an app.
