Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

Yes. In most jurisdictions—including the United States (ESIGN Act & UETA) and the European Union (eIDAS Regulation)—electronic signatures created by drawing, typing, or stamping have the same legal enforceability as handwritten ink signatures on paper.
Yes. You can specify any page number within the document (e.g., page 1 for simple forms, or the final agreement page of a long-form contract).
Transparent PNG files with a clear background yield the best results because they overlay cleanly onto PDF text and signature lines without masking background content.
Yes. We recommend chaining your signed document into the Elixuvo Flatten PDF tool. Flattening bakes the signature image permanently into the page stream graphics, preventing subsequent editing, repositioning, or removal.
No. All signature placement and document compilation happen strictly in memory on the Elixuvo API. Files and signature drawings are immediately discarded once the signed PDF is returned to your browser.
