Frequently Asked Questions

Does this document scanner work on Android phones and iPhones? +
Yes. Vytra Camera Scanner is fully responsive and leverages the HTML5 MediaDevices API. It works seamlessly on Safari (iOS), Google Chrome (Android), Samsung Internet, and desktop webcams without downloading mobile apps.
Are my scanned document photos uploaded to an external server? +
No. The camera stream is captured and processed 100% client-side inside your browser memory using HTML5 Canvas and jsPDF. Your sensitive Aadhaar cards, tax invoices, and certificates never touch any external server, guaranteeing total privacy.
What is the difference between Magic Color and Black & White filters? +
Magic Color enhances text contrast, removes yellowish paper tint, and whitens table backgrounds while preserving official colored ink stamps and passport photos. Black & White converts the page into high-contrast pure monochrome, ideal for legal affidavits, handwritten notes, and low-bandwidth job submissions.
Can I combine multiple camera photos into a single multi-page PDF? +
Yes. Snap as many pages as you need. All captured sheets appear in the gallery drawer where you can review, delete blurry shots, and compile all pages into one single multi-page A4 PDF document.
Can I upload pre-captured gallery photos instead of live camera scanning? +
Yes. Simply click the 'Or Upload Photos' option in the dropzone to select pre-taken images from your device gallery. They will be enhanced with the same scanning filters and compiled into PDF.
