Learn how →A native iOS app that works the way you expect.












No account setup, no learning curve. Three steps, all on your device.
Open files from the Files app or Photos, scan paper with your camera, or send a PDF to PDF Slayer from any app via the Share sheet.
Sign, merge, split, reorder, rotate, convert, protect, or unlock. Every operation runs on your iPhone — it even works in airplane mode.
Your finished PDF is saved locally. It only leaves your device when you choose to share it — never before, never to our servers.
Most PDF apps and every "free online PDF editor" upload your documents to cloud servers. PDF Slayer is fundamentally different.
Signing, merging, splitting, converting, encrypting — it all happens entirely on your device. No internet required. No data transmitted. Ever.
Every feature works in airplane mode. That’s the proof.
Your documents never leave your device.
No analytics, no telemetry, no data collection.
Step-by-step guides for the tasks people actually search for — each one done privately, on your device.
Draw a signature with your finger or Apple Pencil and place it on any page — no Adobe or DocuSign needed.

Learn more →Yes. PDF Slayer processes everything on your device — it even works in airplane mode. Online PDF editors upload your files to their servers; PDF Slayer never does.
Learn more →Use the Merge tool: add your PDFs, drag them into order, and tap Merge. The combined file is created on your iPhone in seconds.
Learn more →Open the Scan tool and capture each page with your camera. Multi-page scans become a single PDF you can sign, merge, or protect — all in the same app.
Learn more →Choose Images to PDF, pick photos from your library or Files, arrange the order, and convert. Each image becomes a page in one PDF.
Learn more →Open the file, choose Password Protect, set a password and permissions, and save. The PDF is AES-encrypted on your device and stays locked wherever you send it.
Learn more →Open the locked PDF, enter its current password, choose Unlock, and save an unprotected copy. You must know the password — PDF Slayer removes protection, it doesn’t crack it.
Learn more →Open the Organize tool to see every page in a grid. Select pages to delete, drag to reorder, rotate sideways ones, and save.
Learn more →Completely. Every feature — signing, merging, splitting, scanning, encrypting — runs on your iPhone with no internet connection. That’s also the proof nothing is uploaded.
Learn more →PDFs often embed the author’s name, the software used, and timestamps. PDF Slayer shows every metadata field and erases them before you share the file.
