Sign a PDF without handing it to a stranger.
Complete form fields, draw or place your signature, and flatten it in — entirely on your device. The contract you sign is never uploaded to anyone's server.
One purchase. No subscription, ever.
Fill it in, sign it off
Everything a form needs, done on the device that holds it.
Draw your signature
Sign with a finger or stylus, then place and resize it exactly where it goes.
Fill form fields
Tap into form fields and type; checkboxes and text land where they belong.
Flatten & share
Flatten the signed result so it can't be edited back, then share it through the system sheet.
Private because of how it's built
PDF Bench has no network access at all. There is nowhere for your documents to go.
Stays on your device
Every file, edit and signature is stored only on your phone. No cloud, no account, no sign-up.
Works fully offline
The app never touches the internet — it behaves the same in airplane mode.
No ads, no tracking
No analytics, no trackers, no data collection. You paid for the app — you are not the product.
