Do I need to install anything?

No. It runs in Safari (or Chrome) on the iPhone. You can optionally add it to your home screen as an app, but it is not required.

Is the contract uploaded while signing?

No — the PDF is processed on the phone itself. Nothing is sent to a server at any point.

Where does the signed PDF go?

Into the Files app (Downloads). From there, use the share sheet to send it back by mail or messenger.

Sign a PDF on iPhone

Someone emails you a contract; you are on your phone; they need it back today. You do not need a Mac, a printer or a subscription app — Safari on your iPhone can do the whole job.

Open the PDF in Haven PDF, draw your signature with your finger in the signature pad, drop it on the signature line, and download. The document never leaves the phone — it is processed in the browser, not on a server — and the downloaded file lands in the Files app, ready to reply with.

How to

Open havenpdf.com in Safari. No App Store visit — the editor runs in the browser.
Open your PDF. Pick it from Files, iCloud or a saved Mail attachment.
Draw your signature. Signature tool → draw with your finger → Add.
Place, resize, download. Drag the signature onto the line, pinch the handles to size it, then Download — the file appears in the Files app.

Finger-drawn, but presentable

The signature pad supports smooth finger drawing with adjustable stroke — sign large, then scale the signature down onto the line, which is the trick to a natural look. Made a mess? Clear and redraw; the pad is disposable, the placed signature is what counts.

Getting the file in and out

In: open havenpdf.com in Safari, tap the file picker and choose the PDF from Mail, Files or iCloud Drive. Out: the signed PDF downloads to Files (Downloads folder), where the share sheet sends it back through Mail, WhatsApp or anything else.

Why not just use Markup?

iOS Markup can sign, but it is easy to nudge the page, it flattens everything immediately, and it offers no PDF editing beyond drawing. In Haven PDF the signature is an object you can reposition and resize precisely before export — and the same editor fills form fields, adds dates as text, and compresses the result if the recipient has a size limit.
