Questions

Are my files uploaded anywhere?

No. This page loads the PDF tools into your browser once, and then works on your file right there on your phone or computer. The file is never sent to mwai or anyone else. Many other PDF websites upload your file to their servers; this one does not.

Is this a legally valid digital signature?

It is a picture of your handwritten signature, like signing a printout and scanning it. It is not a certificate-based digital signature (DSC). Some official forms need a DSC or Aadhaar e-Sign instead.

Is my signature saved anywhere?

No. It exists only on this page and is gone when you close it.

Is it really free?

Yes. There is no sign-up, no limit on how many files you use, no watermark added and no ads.
