Key Features

Perspective Correction

Drag the four corners to match the paper in your photo — the page is automatically straightened into a flat, rectangular scan.

Full Manual Control

Every page can be re-opened and adjusted: corners, rotation, filter, brightness, contrast and black & white threshold.

Color, Grayscale or B&W

Switch between full color, an enhanced document look, grayscale, or a crisp black & white scan mode.

Multi-Page Documents

Capture as many pages as you need, reorder them by dragging, and combine them into a single PDF.

No Server Upload

Every photo and the final PDF are processed entirely on your device using your browser.

Frequently Asked Questions

Does this tool automatically detect the edges of my document?

The tool starts with a sensible default crop and gives you draggable corner handles so you can line them up precisely with your paper — this gives more reliable results than automatic edge detection, especially on busy backgrounds or uneven lighting.

Can I scan multiple pages into one PDF?

Yes. Add as many photos as you need — each becomes a page. Drag the thumbnails to reorder them before creating the PDF.

What is the difference between the filters?

Color keeps the original photo colors. Enhance boosts contrast and brightness for a cleaner scanned look while keeping color. Grayscale removes color. Black & White converts the page into a high-contrast, print-style scan using an adjustable threshold.

Can I fix a page after adding it?

Yes. Tap any thumbnail to reopen it in the editor and adjust the corners, rotation or filter at any time before creating the PDF.

Is my photo uploaded anywhere?

No. Photos are read directly from your device and processed with on-page JavaScript. Nothing is sent to a server at any point.
