In Library, select Import PDF and choose a file with Android's system picker. From another app, use Share or Open with and choose PDF Reader. The app works on a private copy; the original is not modified.
The app restores your last page. Use search to move through text results, thumbnails or Go to page to navigate, bookmarks to save positions, and Settings to select continuous or single-page layout.
Select text to highlight, underline, strike out, or copy it. You can also add notes and freehand drawings. Save annotations before leaving. Drawings and signatures are embedded and may not be removable later.
Tools lets you sign, merge, split, rotate, remove, extract, and reorder pages. The app uses temporary files and backups to protect documents during destructive operations.
Use Make searchable (OCR) for scanned documents. Recognition runs on the device. You can cancel before the final save; the original remains unchanged if processing fails.
Linking Drive is optional. The app uses the restricted drive.file scope and can only access files it created or that you explicitly opened with it.
Password-protected PDFs require the correct password. Damaged or incomplete files must be downloaded again. If a library file is missing, you can keep its entry or remove it.
Email hello@armelix.dev. You can include the app version, device model, steps, and any visible error message, but never send confidential documents unless you choose to.
