How to Use Scan to PDF in 3 Simple Steps

Capture document pages using your camera or upload photo files.
Adjust Border & Filter
Fine-tune crop corners and apply document or black-and-white filters.
Generate PDF
Combine all scanned pages into a standard A4 PDF document.
Features & Technical Capabilities
Our scanner utilizes computer vision algorithms for real-time edge detection, 4-point quadrilateral perspective warping, and image enhancement.
Perspective Warp & Keystoning
Corrects angled shots into flat, rectangular pages as if scanned on a professional flatbed scanner.
Adaptive Document & B&W Filters
Normalizes uneven lighting, removes background paper textures and shadows, and sharpens text characters for maximum readability.
Multi-Page Batch Sequencing
Capture or upload multiple pages in sequence, reorder or rotate individual pages, and export them into a single consolidated PDF.
Place physical documents on a contrasting, dark surface under even lighting to allow the automatic corner detector to snap boundaries accurately.
Important Considerations
Document scanning operational parameters.
Severe Glare on Glossy Photo Paper
Direct camera flash on glossy paper can create blinding reflections. Use ambient room lighting for optimal contrast.
Extreme Low-Light Conditions
Low-light environments may introduce sensor noise; ensuring adequate lighting yields crisp, high-resolution text boundaries.
