Shrink a PDF for email without uploading it.
Compress a heavy file so it fits an attachment limit, or add and remove a password — all on your device, so a confidential file never touches a compression website.
One purchase. No subscription, ever.
Smaller files, kept private
The two things you reach for before sending a PDF.
Compress
Reduce a large PDF's size so it sends by email or message.
Password protect
Add a password to a sensitive file, or remove one you no longer need.
Share cleanly
Send the finished file through the system share sheet to any app.
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.
Questions
Can I compress a PDF without a website?
Yes. PDF Bench compresses on your device — the file never gets uploaded to a compression service.
Can I password-protect a PDF?
Yes. Add a password to protect a file, or remove one from a file you own.
Is it a subscription?
No. One-time purchase, no ads, no in-app purchases.
