Bunker PDF: Merge, Split & OCR

Most PDF apps quietly upload your file to a server to process it — merge, split, compress, whatever you asked for happens somewhere else, on someone else's computer. Bunker PDF doesn't request network access at all. Not "we promise not to upload your files" — the app is structurally incapable of it, because the permission was never asked for. You can check this yourself in your phone's app permissions in about ten seconds.

MERGE, SPLIT, AND ORGANIZE — FREE, NO LIMIT
Combine PDFs, split by page range, reorder or rotate pages, extract specific pages into a new file, and turn photos into a PDF. No cap, no watermark, no time limit.

PRIVATE BY DESIGN, NOT BY PROMISE
Every operation runs entirely on your device. Nothing is uploaded, nothing is logged, there's no account and no server that could see your documents even if it wanted to. Tax forms, contracts, IDs — whatever you're working with stays on your phone.

COMPRESS WITHOUT GUESSING
See the exact before-and-after file size every time you compress a document — a real number for your actual file, not a marketing claim.

REDACT — GENUINELY, NOT JUST VISUALLY
Select pages to permanently destroy the content on them — text, images, everything — replaced with a solid black page, not just covered up. The original content is removed from the file itself, not hidden behind a box someone could see through.

MORE WHEN YOU NEED IT
- Password protect or remove a password from a PDF
- On-device text recognition (OCR) — pull searchable text out of a scanned document, entirely offline
- Export your file history to CSV

RECEIVE AND SEND WITHOUT LEAVING YOUR OTHER APPS
Share a PDF straight into Bunker PDF from Gmail, Files, or anywhere else, then share the result back out the same way.

PAY ONCE, NOT MONTHLY
PDF tool subscriptions in this category are common and often expensive — $5.99/month and up is typical, frequently sold through a short free trial that starts charging automatically. A single one-time purchase unlocks compression, password tools, redaction, OCR, and history export. No trial, no recurring charge, no subscription of any kind.

Built by a solo developer who thinks a PDF tool shouldn't need your internet connection to merge two files.
