Common questions

How is this different from a regular photo?

A regular photo of a document often has perspective distortion (trapezoid shape), uneven lighting, and background clutter. This tool automatically detects the document edges, corrects the perspective to make it perfectly rectangular, and enhances contrast - just like a flatbed scanner would produce.

Do my photos get uploaded to a server?

No. All processing happens entirely in your browser. Your images never leave your device. There is no server upload, no account required, and complete privacy.

What kinds of documents work best?

Any flat document on a contrasting background works well - receipts, letters, book pages, ID cards, business cards, forms, and handwritten notes. Documents on a dark or light desk surface with good lighting produce the best results.

What if the auto-detection does not find the document edges correctly?

If the automatic edge detection does not produce perfect results, a manual corner editor will appear. You can drag four colored dots to precisely mark the four corners of your document, and the perspective correction will use your manual input instead.

Which output mode should I choose?

Choose 'Color' to preserve the original colors of your document (best for photos, certificates, colored forms). Choose 'Grayscale' for a clean, professional document look without color distraction. Choose 'Black & White' for pure text documents where you want maximum contrast and small file size.

Is there a file size limit?

There are no hard limits. The tool processes images entirely on your device, so larger images (above 200MB) may take longer but will not be blocked. A soft warning will appear for very large files.
