100% Client-Side Privacy
All processing runs entirely in your browser. Files are never uploaded to any server. Refreshing or closing the app wipes your data completely.
Reading Modes
Use the right panel to switch reading modes. Options like True Black are perfect for OLED screens, while Sepia and Blue Light reduce eye strain.
Annotations & Tools
Use the floating toolbar at the bottom to draw directly on the document.
- Cursor: Navigate and interact normally.
- Pen: Freehand drawing (scales accurately with zoom).
- Highlighter: Semi-transparent wide marker.
- Eraser: Precision eraser to remove specific strokes.
- Clear: Wipe all annotations on the current page instantly.
Watermarks
Apply custom text watermarks via the right sidebar. You can target either the Current Page Only or All Pages in Workspace. Set your desired position (e.g., Center, Top Left) and color before applying.
OCR Extract
Need text from a scanned document? Select the language and target (Current Page or All Pages) to extract text. You can cancel long extractions midway, copy the result, or download it as a .TXT file.
Export Capabilities
Export your work securely using the bottom right controls.
- Targets: All Pages, Current Page, or Custom Range (e.g., "1-3, 5").
- Formats: Export as a merged PDF, a ZIP archive of images, or a standalone JPG.
Workspace Limits
To ensure optimal performance and prevent browser crashes, the workspace is limited to 10 files per upload, 50MB per file, and a maximum total of 200 pages.
Task Management
Heavy operations like OCR, Exporting, and loading large files are safely queued and managed to prevent browser freezing and crashes.
