How to sign a PDF online
Signing a PDF online takes less than 60 seconds. No software downloads, no printer, no scanner. Upload your document, place your signature, and you're done.
Step 1: Upload your PDF
Drag and drop your PDF into SignOwl or click to browse. We support files up to 25 MB on Pro plans. Your document is encrypted in transit and at rest.
Step 2: Add signature fields
Click where you want signatures placed. You can add fields for signature, date, initials, and text. For documents you're sending to others, place fields where each signer needs to sign.
Step 3: Sign or send
If you're signing yourself, draw or type your signature and download the signed PDF. If you're sending to others, enter their email addresses and hit send. Signers get a link — no account needed.
What you get after signing
Every signed document includes a court-grade audit trail with timestamps, IP addresses, and a SHA-256 hash to verify the document hasn't been tampered with. You can verify any signed document at signowl.app/verify.
