Honest overview
Adobe Acrobat Online is a heavyweight industry standard, but free users are abruptly blocked by an Adobe ID sign-in modal after filling a document, and free e-signature requests are strictly limited before requiring a recurring paid subscription. PdfPixels Sign PDF lets you draw, type, or upload your signature, stamp dates and checkmarks, and download the finished signed document immediately in your browser — completely free, on any device, with no account creation required.
