Frequently Asked Questions

  • Are my documents uploaded anywhere?

    No. Detection, perspective correction and export all run in your browser. Your photos never leave your device. The first time you add a photo, the tool downloads its image-processing engine once (about 13 MB) and your browser caches it for next time.

  • How does corner detection work, and what if it gets it wrong?

    The tool looks for the largest four-sided shape with clear edges, such as a sheet of paper on a darker table. If it finds one, the page is cropped and straightened automatically. If not, it starts with a slightly inset rectangle. Photos with low contrast between page and background are the hardest; corners can then be adjusted by hand.

  • Which enhancement profile should I pick?

    Original keeps the colours exactly as photographed and only straightens the page. Magic colour evens out shadows and brightens the paper while keeping colour, which suits forms and printed pages. Grayscale does the same without colour and suits text documents. Black & white gives pure black text on white and the smallest files; it works best on text-only pages.

  • Can I export a PDF, and which image formats work?

    You can add JPEG, PNG and WebP photos. At the end, choose one PDF with all pages (A4, US Letter or fit to each page) or separate image files with a ZIP download. HEIC/HEIF photos from iPhones are not supported by most browsers: set the camera to “Most Compatible”, or convert the photo to JPEG first.
