You don't need Adobe Acrobat or a paid e-signature service to sign a PDF. Here's how to add a legally valid electronic signature to any PDF document in your browser — for free.
Go to pdfeditor.onl/sign-pdf. No account or subscription is required. The tool works on all devices.
Click the upload area or drag your PDF onto the page. The document is loaded into your browser's memory only — it is never transmitted to a server.
On the signature canvas, draw your signature using your mouse, trackpad, or finger on a touchscreen. The canvas supports variable pen pressure for a natural-looking result. You can clear and redraw as many times as needed.
Tip: On a phone or tablet, use a stylus or your fingertip. Slow, deliberate strokes produce cleaner signatures than fast swipes.
After drawing, select which page to sign. Your signature will appear as a draggable element — position it exactly where required on the document. You can resize it freely.
Click Download Signed PDF. Your signature is permanently embedded into the PDF page as a vector element — sharp at any zoom level and tamper-resistant.
