How do I sign a PDF without uploading it?

Open the PDF in LuniPDF's Fill & Sign tool. It finds the signature, initials and date spots, you set up your signature once, then tap Next to fill each spot and download. Everything runs in your browser — the PDF is never uploaded.

Can I sign a PDF on my iPhone?

Yes. Open the tool in Safari, draw your signature with your finger or type it, tap Sign here to fill each spot, and save the signed PDF to Files.

How it works

Choose the PDF you need to sign. LuniPDF reads it in your browser and finds every signature, initials and date spot — including lease footers like "Landlord (____) Tenant (____)".
Pick who you are signing as (for example Landlord or Tenant), type your name and draw or type your signature. Your initials are made for you.
Tap Start signing. Each tap on Sign here ▶, Initial here ▶ or Add date ▶ fills the highlighted spot and jumps to the next one. Add extra signatures, dates, text or check marks anywhere with the toolbar.
Tap Finish & download. The signed PDF is saved to your device.

Frequently asked questions

Are my documents uploaded anywhere?

No. The PDF is opened, signed and saved entirely in your browser. Your contract never touches a server.

Is this a legally binding e-signature?

In the US and many countries, a drawn or typed signature on a PDF is generally accepted for everyday agreements. Some documents need a certified digital-signature service — check with the other party if unsure.

How does it find where to sign?

It reads the words printed on the PDF — "Signature", "Initials", "Date" next to blank lines, footer initial boxes, and fillable signature fields — all in your browser. If a spot is missed, add it yourself with the toolbar.

Will there be a watermark?

Never. The signed PDF contains only your document and your signature.
