Is an electronic signature legally valid?
In the US (ESIGN Act), the EU (eIDAS) and many other countries, electronic signatures are legally recognised for most contracts. Some documents, such as wills or certain government forms, have special rules; check with the recipient if unsure.
What’s the difference between an electronic and a digital signature?
An electronic signature is a visible mark of agreement, like the one this tool adds. A digital signature is a cryptographic certificate embedded in the file that proves who signed and that nothing changed afterwards. This tool does not add certificates.
Is it safe to use with confidential documents?
Yes. The file is opened by your own browser and processed in your device’s memory. It is never uploaded, so no server, including ours, ever receives a copy. That makes it suitable for contracts, IDs, medical or bank documents.
Is it really free?
Yes. There is no sign-up, no watermark, no daily limit and no paid tier hiding the useful settings. Because your device does the work, it costs us almost nothing to run.
