Simple Pdf Utils

Your documents never leave your phone.

Simple Pdf Utils merges, edits, and compresses PDFs, photos, and Word files entirely on your device — no uploads, no account, no ads, and literally no networking code. It even works fully in Airplane Mode. It's free, with no subscriptions and no "premium" tier.

WHAT IT DOES
• Combine PDFs, photos, and Word documents (.docx) into one file
• Reorder pages by dragging, or swipe a row left/right to mark it for removal
• Add text to any page — pick font, size, and color; drag to reposition
• Rotate any page 90° clockwise with one tap
• Preview any page full-screen with pinch to zoom
• See each page's byte cost to find what's bloating your file
• Compress oversized pages instantly — choose page-by-page
• Combine multiple photos onto a single page in a grid layout
• Save through the share sheet — Google Drive, Gmail, Messages, or anywhere else

PRIVATE BY DESIGN
Built for the documents you'd never want sitting on someone else's server — contracts, receipts, medical records, scans, and IDs. Most PDF tools online, and many on the Play Store, upload your file to a server to do their work. Simple Pdf Utils never does:
• No accounts, no sign-up, nothing to log in to
• Does not collect, transmit, store, or share any data
• Contains no networking code at all
• A strict Content Security Policy blocks every outgoing connection from inside the app
• Asks for no special permissions — the system file picker and share sheet handle everything

You can verify all of this with Airplane Mode. The app works identically.

GOOD FOR
• Combining receipts before submitting an expense report
• Tidying up scans of paperwork
• Stripping irrelevant pages from contracts before sharing
• Merging photos from your gallery into a single PDF
• Adding a handwritten note or signature line to a document
• Shrinking image-heavy PDFs that are too big to email
• Converting a Word draft to PDF when you only have the file

HOW IT WORKS
• The app uses the system document picker and photo picker for input — no storage permissions needed on Android 13 and above.
• Images from your gallery are converted to JPEG and wrapped as PDF pages, all on-device.
• Word documents are converted to HTML locally (via the open-source mammoth library) and rendered to PDF using Android's built-in print engine — no third-party cloud involved.
• When you add multiple photos at once, you can lay them out as a grid on a single page rather than one page per photo.
• Text annotations are baked into the page at export time using pdf-lib, a fully on-device PDF library.
• When you save, the result goes to the standard Android share sheet. You decide where it ends up.
• Per-page compression rasterizes the chosen page to a JPEG sized to fit the budget — useful for image-heavy scans (compressed pages become image-only, so text is no longer selectable).

NOTE ON WORD DOCUMENTS
.docx conversion works best for straightforward documents (body text, simple tables, headings). Complex formatting — multi-column layouts, text boxes, charts, headers/footers — may look different or be omitted. The app shows a warning when a Word file is loaded.

NO CATCHES
Free. No upsells. No ads. No subscriptions. No "premium" tier. The app is what's on this page.
