Three ways to make your signature

✒︎

Draw

Sign with your finger or a stylus, exactly like paper. Saved to your device's library so you never redraw it.

𝒯

Type

Type your name and pick a cursive style — or use the /s/ Your Name convention used on legal filings.

Photo

Photograph your inked signature on paper. Inkwell lifts the ink and drops the background, leaving a clean signature.


How it works

1

Open a PDF

Pick any document from your device. Word files work too — export to PDF first.

2

Place your marks

Tap to drop a signature, initials, today's date, or free text. Drag to position; pinch to resize.

3

Save

Export a flattened, signed PDF — named however you like — straight back to your device.


Private by architecture

Your documents never leave your device. Inkwell has no server — the entire app runs in your browser, and the PDF you sign is read, marked, and saved locally. There is nothing to upload, no account to create, and nothing to track. Add it to your phone's home screen and it works fully offline after the first launch.

One honest note: Inkwell marks up your PDF; it does not attach the tamper-evident audit trail that enterprise services like DocuSign provide. For everyday signing — consent forms, approvals, contracts, school and rental paperwork — that's exactly what you want. For high-stakes legal disputes, those services still have their place.

Common questions

Can I sign a PDF without a DocuSign subscription?

Yes. For everyday personal signing — leases, consent forms, contracts — you don't need a subscription service. Inkwell is a one-time $9.99 purchase that signs PDFs entirely on your own device, with no account and no monthly fee. (Your device also has free options: iPhone's built-in Markup and Adobe's free Fill & Sign both handle basic signing — Inkwell exists because they're fiddly for signatures, initials, dates, and reuse.)

Is there a one-time-payment alternative to e-signature subscriptions?

Inkwell is a buy-once PDF signer: $9.99 one time, no recurring fee. It supports drawn, typed (including the /s/ Your Name legal convention), and photographed signatures, plus initials, dates, and text fields, with a saved signature library so you never redraw.

Can I sign a PDF offline, without uploading my document?

Yes. Inkwell runs entirely in your browser — the PDF is read, signed, and saved on your own device. Nothing is uploaded to any server; there is no server. Installed to a phone's home screen, it works fully offline after the first launch.

Is a signature made this way legally valid?

For most everyday documents, yes — U.S. law (the ESIGN Act and UETA) recognizes electronic signatures generally. What Inkwell does not provide is the tamper-evident audit trail that services like DocuSign attach, which can matter in high-stakes disputes. For ordinary signing, a placed signature is exactly what's expected. (This is general information, not legal advice.)

How is Inkwell different from DocuSign?

DocuSign is a subscription service built for businesses: documents pass through its cloud, and plans start around $10–15 per month with limits on how many documents you can send. Inkwell is built for individuals: a one-time $9.99 purchase, documents never leave your device, unlimited signing. It doesn't do multi-party workflow routing or audit trails — it does personal signing, simply.
