Step by step
- 01
Open the signer and upload your PDF
Go to the DocSignHub signer and drag your PDF into the upload area, or click to choose it from your device. Multi-page documents are fully supported, and the file is loaded into your browser — nothing is uploaded to a server.
- 02
Create your signature
Draw your signature with a mouse, trackpad, or finger; type your name and pick a handwriting font; or upload a photo of your real handwritten signature. You can reuse the same signature across every page.
- 03
Place the signature and download
Drag the signature to the exact spot the document requires, resize it to fit the signature line, and add a date if needed. Click download to save your signed PDF instantly.
Why sign a PDF in the browser?
Most PDFs only need a single signature — a contract, a consent form, an application. Installing desktop software or creating an account on a cloud service is overkill for a one-minute task, and it means handing a private document to a third party.
A browser-based signer removes both problems. The PDF is processed locally using WebAssembly, so the document stays on your computer or phone. There is nothing to install, nothing to pay for, and no sign-up between you and a finished, signed file.
Three ways to create your signature
There is no single "correct" way to sign — pick whichever produces a signature you are happy with:
- Draw it: best on a phone or tablet where you can sign naturally with a finger or stylus.
- Type it: enter your name and choose a handwriting-style font. Fast and consistent, and ideal when you do not have a touchscreen.
- Upload it: photograph your real pen-on-paper signature, then drop the image in. This gives the most authentic result for formal documents.
Placing and sizing the signature correctly
A signature that overlaps the printed text or sits crooked on the line looks unprofessional and can cause a document to be rejected. After placing your signature, drag it so its baseline rests on the signature line and resize it so the width roughly matches the space provided.
For multi-page documents, repeat the placement on every page that requires initials or a signature. Many agreements need initials on each page and a full signature only on the last.
Is an electronic signature legally valid?
In most countries, electronic signatures are legally recognized for the vast majority of everyday documents. In the United States the ESIGN Act and UETA give electronic signatures the same legal standing as handwritten ones; in the EU, eIDAS does the same. That covers contracts, NDAs, offer letters, rental agreements, and consent forms.
A small number of documents — certain wills, some property deeds, and specific court filings — may still require a traditional wet signature or notarization. When in doubt for a high-stakes legal document, confirm the requirement with the requesting party.
