Sign Any PDF: Fill Forms
Document Signature & Scanner
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Fill in and sign any PDF free, export with one payment. Scan paper, autofill your details, lock fields and encrypt. No subscription, nothing uploaded.
Fill in and sign any PDF on your iPhone or iPad. Buy once, own it forever — one payment, no subscription, nothing to renew.
Sign Any PDF is for the moment a form lands in your inbox and has to go back today. Open it straight from Mail, Files or Messages, drop your signature on the line, and send it. Everything happens on your device, and nothing is ever uploaded.
TRY THE WHOLE THING FIRST, FREE
• Open any PDF and fill it in completely before you decide to buy
• Draw your signature once and place it exactly where it goes
• Add initials, typed text, dates, checkmarks and crosses on every page
• Scan paper to PDF with the camera, with edges and shadows handled
• Keep 2 saved signatures and 1 set of initials
Exporting and sharing the finished PDF is what Pro unlocks.
PRO — ONE PAYMENT, YOURS FOREVER
• Export and share your signed PDFs, as many as you like
• Autofill: save your name, address and phone, then tap them into any form
• Page tools: reorder, rotate and delete pages, or add pages from another PDF
• Lock filled fields so the recipient cannot change what you entered
• Password-protect an export with AES-256 encryption
• Unlimited saved signatures and sets of initials
One purchase, covering every device on your Apple ID, for good. It is not a subscription and there is nothing to renew.
BUILT FOR REAL PAPERWORK
Your signature is flattened into the page itself, so what you see is exactly what your bank, landlord or HR portal sees. There are no live annotations to render differently in Preview, Acrobat or a web viewer. Page size is preserved too: Letter stays Letter, A4 stays A4, and a landscape scan stays landscape.
PRIVATE BY DESIGN
No accounts. No uploads. No analytics SDKs, no ad networks, no tracking of any kind. Your documents, signatures and saved details are stored only on your device. Full privacy policy: https://mackgrissom.github.io/signfast-site/privacy.html
GOOD TO KNOW
Sign Any PDF places visible signatures and text on a document. It does not create certificate-based digital signatures, and does not verify anyone else's.

Ratings & Reviews
Pro now covers exporting and sharing your signed PDFs, and it is still a one-time purchase — buy once, own it forever, with no subscription and nothing to renew. Filling in and signing a document is still completely free, so you can do the whole job and see the finished result before deciding.
Everyone who already bought Pro keeps it. Tap Restore purchase in Settings if it does not appear straight away.
Also in this release:
• A clearer export screen that shows exactly what Pro includes.
• Restore purchase is now reachable directly from the export screen.
