Signature Notes
Electronic Signature: A visual representation of your signature placed on the PDF.
Draw / Type / Upload: Create a signature by drawing, typing a name, or uploading a photo — we remove the paper background automatically.
Resize & rotate: Drag corner handles to resize; use the top handle or rotate buttons to angle the stamp.
Readability: For typed signatures, tune ink strength, sharpness, and text weight. Uploaded photos have cutout and sharpness sliders.
Initials: Place a smaller initials stamp on individual pages, plus a full signature where needed.
Date: Optionally add an editable date next to the signature.
Multi-page: Add the same signature or initials to multiple pages before saving.
Privacy: Uploaded signature photos and cutouts are stored only as temporary files and deleted after processing (cleanup within ~10 minutes).
Note: This is a visual signature stamp, not a cryptographic digital signature.

Sign PDF Online Free — Draw, Type, Resize & Rotate Signatures

Add electronic signatures, initials, and dates to contracts, forms, and agreements without printing and scanning. PdfPeaks lets you draw, type, or upload a signature, then drag, resize from corner handles, rotate, and sharpen ink for crisp readability across multiple PDF pages.

How It Works

Upload the PDF, create a signature (draw, type, or upload PNG/JPG), tune readability with ink strength and sharpness controls, place stamps on one or more pages with drag/resize/rotate, then download the signed file. No account is required for standard use.

  • Step 1 — Upload: Open the PDF that needs a signature.
  • Step 2 — Create stamps: Draw, type, or upload your signature; adjust typed ink strength, sharpness, and weight — or cutout threshold for photo uploads; optionally enable a date stamp.
  • Step 3 — Place & download: Drag to position, resize from any corner, rotate with the top handle or buttons, add stamps to more pages, then save and share the signed PDF.

Security & Privacy

Files are encrypted in transit and deleted after processing — see our Privacy Policy for details.

Common Use Cases

  • Freelance: Return signed statements of work quickly.
  • Real estate: Initial disclosure pages and sign the final page from mobile.
  • HR: Complete onboarding forms with signature plus date.
  • Small business: Accept vendor agreements without fax or printing.
  • Personal: Sign permission slips, rental addenda, and school forms.

Tips for Best Results

Electronic signatures may not meet all jurisdictional requirements for every contract type — verify local rules for high-value agreements. This tool places a visual signature stamp (not a cryptographic digital signature). Pair with Protect PDF when sharing sensitive signed files. Scanned an ID first? Start with JPG to PDF / ID Card Scan, then sign the copy here. Supported format: PDF (.pdf); signature images PNG/JPG.
