Why PDF Toolkit instead of other PDF editors?
• Truly offline — most "free PDF editor" apps upload your files to a server. We never do.
• No watermarks on output — most competitors stamp every page with "Made with X".
• Lightweight — under 60 MB with full OCR built in.
• Modern Android — Jetpack Compose UI, not a slow WebView wrapper around a PDF.js mirror.
• Indie-built — no surprise paywalls on features that used to be free, no aggressive upsell dialogs.

USE CASES
• Scan a paper receipt and convert it to a searchable PDF
• Sign a rental agreement on your phone and email it back in 30 seconds
• Combine multiple scanned pages into one document for upload to a portal
• Convert a class handout PDF into Word so you can edit it
• Shrink a 20 MB PDF to fit a 5 MB email attachment limit
• Add a watermark to drafts before sharing

PERMISSIONS
• Storage — to read your source PDFs and save the results
• Internet — only for ads (free tier) and crash reporting; never to upload your PDFs

REQUIREMENTS
• Android 7.0 (Nougat) or newer
• Works on phones and tablets

SUPPORT

Built by an indie developer who got tired of PDF apps that upload private documents to sketchy servers, plaster watermarks on every page, and lock basic features behind aggressive subscriptions. PDF Toolkit does the job, respects your privacy, and works offline.
