A PDF Reader That Respects Your Privacy
Most online PDF readers upload your file to a server to process and display it. This creates a risk for sensitive documents like bank statements, medical records, or legal contracts.
Browser-Based Rendering
Andromeda PDF uses Mozilla's PDF.js library to render documents directly in your browser's memory. Your file is never sent to the cloud. It's as secure as opening it from your desktop, but without installing software.
Technical Insight: Pure Canvas Rendering
Many online viewers use "iframe embedding," which can still leak data. Andromeda uses raw vector parsing.
We parse the binary PDF stream and instruct the HTML5 <canvas> element to draw each line, curve, and font glyph individually. This means the "image" you see is generated 100% locally by your device's GPU, guaranteeing that no external server ever sees the visual output of your file.
Key Features
- ✓Instant Load: No upload wait times. Drag, drop, and read immediately.
- ✓Zoom Control: Inspect fine details or view the whole page at once.
- ✓Cross-Platform: Works on Windows, Mac, Linux, and Chromebooks equally well.
Troubleshooting
File won't open?
Check if the PDF is password protected. We currently support standard unlocked PDFs best.
Slow rendering?
Large high-res scans may take a moment to process on older devices as we use your device's CPU.
