PDF Plain and Simple — description
PDF Plain and Simple is a complete PDF toolkit that runs entirely on your device. Your files are never uploaded or tracked, and every tool is unlocked from the start, with no paywall.
VIEW & READ • Fast, smooth PDF viewer (powered by pdf.js) • Light, dark & system themes • Works fully offline. The app doesn't even request internet access.
ORGANIZE • Merge multiple PDFs into one • Split by page range or every N pages • Reorder, rotate, delete & extract pages • Insert blank pages, add page numbers
ANNOTATE & SIGN • Highlight, draw & add text notes • Save your signature once, stamp it anywhere
IMAGES to PDF • Build a PDF from camera photos or your gallery • Crop & rotate before converting
SECURITY & SIZE • Add or remove password protection • Add text or image watermarks • Compress large PDFs • Fill & flatten PDF forms • Export any page as an image
Built by an indie developer who got tired of "free" PDF apps that bombard you with full-screen ads, fake "premium" upsells, and surprise subscriptions. PDF Plain and Simple is free now and will stay that way. If you'd like to support development, there's an optional donation link in Settings.
