Sign PDF Online Free – Add Your Signature to Any PDF
PdfPeaks Sign PDF is a free online tool for adding an electronic signature to a PDF. Upload your file, then draw, type, or upload a signature, add initials and a date, and drag, resize, or rotate each stamp on any page. No sign-up is needed. It places a visual signature, not a certificate-based digital signature.
Got a contract, form, or agreement that needs your signature today? Upload the PDF here, add your signature, and download the signed copy. You don’t need a printer, a scanner, or an account.
Draw your signature with a mouse or finger, type your name in a handwriting-style font, or upload a photo of your real signature and let the tool remove the paper background. Then drag it to the right spot, resize it from the corners, rotate it, and add initials or a date wherever they’re needed. It works in any modern browser on Windows, Mac, Linux, Android, and iPhone. Choose your PDF below to start.
How It Works
- Upload your PDF. Drop the file into the box or tap Select PDF.
- Create your signature. Choose Draw, Type, or Upload Signature. For typed signatures, pick a font and adjust ink strength, sharpness, and weight. For a photo, use clean white paper and good light, then fine-tune the cutout.
- Add initials and a date (optional). Make a smaller initials stamp for each page, and switch on the date stamp to place today’s date beside your signature.
- Place it. Drag the stamp onto the page, resize it from a corner, and rotate it with the top handle. Use Add to this page to repeat it on other pages.
- Download. Click Add Signature to PDF, preview the result, and download your signed file.
Security & Privacy
Your PDF is encrypted in transit and deleted after processing. Uploaded signature photos and their cutouts are kept only as temporary files and removed within about ten minutes. If you tick Remember my signature on this device, it’s stored in your own browser only, not uploaded and not tied to an account.
Signed documents are often sensitive. After signing, you can lock the file with Protect PDF before you share it. Details are in our Privacy Policy.
Common Use Cases
- Freelancers: return signed statements of work and quotes the same day.
- HR and onboarding: complete offer letters and forms with a signature plus date.
- Real estate and rentals: initial each page and sign the last one from your phone.
- Small business: accept vendor agreements without printing or faxing.
- Students and parents: sign permission slips, fee forms, and school paperwork.
- Job applications: sign declarations and consent pages for employers.
- Everyday admin: sign any PDF a bank, landlord, or office emails you.
Tips for Best Results
- Photograph your signature properly. Use a dark pen on plain white paper in bright, even light, and hold the camera straight on.
- Use Signature Maker first if you don’t have a signature image yet: Signature Maker creates a clean one you can upload here.
- Fill the form first. Complete blanks with Fill PDF Forms, then sign.
- Scanned a paper document? Turn photos into a PDF with JPG to PDF, then sign it here.
- Soft or faint signature? Raise ink strength and sharpness, or tighten the cutout for photo uploads.
- Know the limit. This tool adds a visual stamp. It is not a certificate-based digital signature. For high-value contracts, check which kind of signature the other party requires.
- Lock it afterwards with Protect PDF when the file is sensitive.
