When to sign a PDF online
Contracts, consent forms, delivery receipts, NDAs — whenever a document needs your handwritten approval, draw your signature once and place it wherever the line asks for it. An electronic signature like this — your own handwritten mark on the document — is what everyday agreements mean by signing. You can sign multiple pages of the same document in one pass.
Signing runs entirely on your device, so confidential agreements never leave your computer.

Frequently asked questions
Is this a legally binding signature?
It places a handwritten-look image of your signature on the document — an electronic signature in the everyday sense, the same as printing, signing, and scanning. It does not add a cryptographic digital signature (a certificate-based one); if your counterparty requires that level, use a dedicated e-sign service.
Can I sign multiple pages?
Yes. Place the signature on as many pages as you like — each placement can be moved and resized independently, and all of them export in one click.
Can I use a photo of my signature instead of drawing?
This version supports drawing with mouse or finger. Placing an image file as a signature is on the roadmap.
Will my signature look blurry when printed?
No. The pad records your strokes at the display's native resolution and embeds the trimmed bitmap as a lossless PNG into the PDF.
Does signing change anything else in my PDF?
No. Your signature image is drawn on top of the original pages — text, images, metadata, and page rotation are preserved untouched.
Is my document uploaded anywhere?
No. Drawing, placing, and exporting all run entirely in your browser.
Do I need an account to sign a PDF here?
No. Open the page, drop your file, draw and place your signature, download the signed PDF. There is no signup step anywhere in the flow, and the file never leaves your device.
What about a free e-signature with no sign up for sending to others?
Placing your own signature, this page is exactly that. Sending a document for someone else to sign works differently: the eSign service needs a free account, because audit trails and completion certificates have to attach to an identity. Its free tier sends 3 documents a month with up to 2 signers.
