Scan, edit, and mark up your PDFs.

True on-device text editing
Tap the text. Change the text. On your device.
PolyPDF edits the real content stream underneath the page, powered by our custom PolyPDFKit engine, so your changes become part of the document itself. It all happens on your device, so your files never leave your iPad.
- Edit the contentTap any line and change the actual text — the way paid desktop editors do.
- Formatting is preservedBold, italic, font family, size, and color all survive the edit.
- Inline, tap-to-editA caret appears exactly where you tapped — and a rich formatting toolbar rides above the keyboard.
- Resize & reshape the edit areaDrag handles to squeeze or expand the text column, or extend the selection across more lines.
- Undo / redo every changeExperiment freely — step back and forward through every edit.

- Real content-stream editing of existing text, images and vector paths.

- Not a licensed black box or cloud API — we own it, so we can keep pushing what's possible.
PolyPDFKit · for developers
License the engine behind PolyPDF.
The same on-device PDF editing engine that powers PolyPDF will soon be available to license. Embed real content editing into your own iOS, iPadOS and macOS apps — or partner with us on a fully custom build. No servers, no black box.
SDK licensing — coming soonOn-device & private
Runs entirely on your users' devices. No servers to operate, no documents leaving the device — privacy by default.
Real content editing
Edit existing text, images and vector paths at the content-stream level — the real document, not overlays.
Native Swift framework
A drop-in framework for iOS, iPadOS and macOS. No web views, no bridging — just Swift APIs.
No recurring fees
No in-app purchases, nothing to host, and no per-document API fees. It works fully offline, so there's no infrastructure to scale.
Format fidelity
Edits preserve the original fonts, weight, size and color, so documents keep looking exactly as authored.
Ship-proven
The exact engine shipping in PolyPDF on the App Store — not a prototype or a roadmap promise.
Building something custom?
Whether it's a custom deployment, a white-label PDF app, or real text editing embedded in your own product — we'll help you ship it, working directly with the people who built PolyPDFKit.
Your documents never leave your device.
There's no cloud round-trip, no account to create, and nothing to upload. Every edit, scan and annotation happens locally on your iPhone or iPad. The only place anything syncs is your own private iCloud — if you choose to turn it on.
Independent software
An indie app.
PolyPDF is an independent product — no investors, no data brokers, no growth-hacking playbook.
