TinyPDF - PDF Tools

TinyPDF is a fast, private, offline PDF toolkit. No accounts, no cloud uploads, no daily limits, no paywalls. WHAT YOU CAN DO: Merge — combine multiple PDFs into one, in any order you choose. Split — extract page ranges like 1-3, 5, 7-9 into separate files. Compress — shrink image-heavy PDFs with three quality presets; text stays razor sharp. Watermark — stamp diagonal text (e.g. DRAFT, CONFIDENTIAL) with adjustable opacity. PRIVACY FIRST: Everything happens on your device — your documents never leave your phone. Files are picked through Android's system file picker; no broad storage permission. Password-protected PDFs open only with the password you enter; it is never stored. No account, no tracking by us. OUTPUT: Saved straight to your Downloads/TinyPDF folder. Share or open results right from the app. TinyPDF shows a small banner ad to stay free.
