How to sign a PDF with OnyxPDF
- Drop your PDF into the tool.
- Create your signature: draw it on the pad, or type your name.
- Drag the signature onto the page and position and size it.
- Click “Save” and download the signed PDF.
Why do it in your browser instead of uploading?
- No account and no upload: the contract you are signing never passes through an e-sign company’s servers.
- Free — the big sites funnel signing into accounts and paid plans; here it is a plain local tool.
- Placement is visual and exact: you see the page and put the signature on the line, not in a guessed box.
- The signature is embedded into a standard PDF that any reader can open.
Good to know (honest limits)
- This is a visual signature baked into the document, not a cryptographic digital signature (PKI certificate) and not a multi-party e-sign workflow with audit trails — regulated workflows that require those must use a dedicated e-sign service.
- A drawn signature’s legal weight varies by jurisdiction and document type; for high-value contracts, check what yours requires.
Frequently asked questions
Is a signature made here legally binding?
A drawn or typed signature image is accepted for many everyday documents, but it is not a certificate-based digital signature and this tool provides no audit trail. For regulated or high-value contracts, use a formal e-sign service.
Can I sign on my phone?
Yes. Draw with your finger on the signature pad — the tool is fully touch-friendly.
Do I need an account to sign?
No account, no email, no upload. The signed PDF is created in your browser and downloaded to your device.
Can other people request signatures through this?
No. This is a personal signing tool, not a send-track-and-collect e-sign workflow — those need servers and accounts by design, which this site deliberately has none of.
