Sign
Web and iOS: draw or load an image, then freely place the signature, optional date and location; everything stays local. Only the web isolates a white background and offers the prepared PNG separately. iOS preserves the image background or existing transparency and shares only the finished PDF. This is a simple electronic signature, not a qualified one.

Frequently asked questions
What kind of signature is this?
A simple electronic signature, not a qualified electronic signature.
Can I load a signature image?
Yes. PNG, JPG or WebP and the PDF may each be up to 150 MiB; the prepared PNG for embedding may be up to 20 MiB. On the web, a white background is made transparent locally and the prepared signature can be saved separately as PNG. iOS re-encodes the image locally as a fresh sRGB PNG without source metadata or embedded profiles but preserves its background or transparency and shares only the finished PDF.
Where is it placed and how large is it?
Bottom left, centre and right are starting positions. You can then independently drag and scale the signature, optional date and optional location on the selected page; everything stays inside the visible page. Date and location are each one line of up to 120 characters. Characters unsupported by the embedded PDF font are clearly rejected, not substituted.
