FAQ

Q: Can I scan multiple pages or an entire book in one go?

A: Absolutely. The app’s edge‑detection algorithm works in real time, so you can snap page after page without stopping. When you’re finished, the app assembles the images into a single PDF, making bulk‑scanning a smooth, seconds‑long process.

Q: What kinds of documents or objects can I scan?

A: Anything that fits in the camera frame can be scanned: paper receipts, IDs, handwritten notes, recipes, photographs, business cards, whiteboard scribbles, and even printed book pages. The scanner adjusts to both color and black‑and‑white material, giving you flexibility for any situation.

Q: How does the enhancement feature improve my scans?

A: After a capture, you can apply a range of filters that boost color vibrancy or sharpen black‑and‑white text. The app also lets you crop, rotate, reorder, or merge pages, and you can fine‑tune brightness and contrast manually. The result is a crystal‑clear PDF that looks as good as a professional scan.
