Fill and sign alternative

Fill and sign simple PDFs locally.

Add visual signatures, text, marks and supported form-field edits in your browser, then export the finished PDF.

Visual signatures

Place signature-style marks, initials or approval text on PDF pages.

Supported forms

Edit supported AcroForm text, checkbox, dropdown, list and radio fields.

Flatten export

Optionally flatten supported form fields into the exported copy.

For lightweight signing, not enterprise e-sign.

Slay PDF is a practical fit when a document needs a visible signature mark or filled form fields before sending. It is not a certificate-based signing or identity verification platform.

The benefit is speed and locality: import the file, add the visible mark or form edits, and download the finished PDF without uploading it to Slay PDF.
