Frequently Asked Questions
How does the perspective deskew feature flatten angled photos?
Our built-in editor provides an interactive 4-corner perspective warp grid. Drag the corner pins to the edges of your document, and our matrix homography engine transforms the slanted photo into a flattened rectangular page.
Can I upload photos from my phone gallery instead of taking live photos?
Yes! In addition to live webcam and rear phone camera scanning, you can upload existing document pictures directly from your device storage or camera roll.
Does the scanner support A4 and US Letter paper sizes?
Yes. You can select standard A4, US Letter, Legal, or Fit to Document dimensions. The tool automatically centers and scales your scans with clean margins.
How do the document enhancement filters improve scan readability?
Our Magic Color and B&W filters run an adaptive thresholding algorithm that removes yellowing, uneven lighting, and desk shadows while enhancing black text ink.
Are my camera feed and scanned documents stored on any server?
No. All camera stream captures, image transformations, perspective warping, and PDF compilation run 100% locally inside your device browser RAM.
