Photograph a document; its edges are detected and the page is straightened. Nothing is uploaded.
How it works
Turn photos of paper documents into a clean, straightened PDF — like a scanner app, but in your browser. Take a photo with your camera (or pick an existing one): the document edges are detected automatically, you can fine-tune the corners by dragging them, and the page is deskewed with an optional grayscale or black-and-white finish. Add as many pages as you need before downloading. Everything runs on your device, which matters here more than anywhere: photos of IDs, contracts and receipts are never uploaded to any server.
Frequently asked questions
How does the document detection work?
Edge detection (OpenCV) runs in your browser to find the document outline; you can always adjust the four corners by hand before adding the page. The first use downloads the engine (~10 MB), which is cached for next time.
Are my photos uploaded to a server?
No. Detection, straightening and PDF creation all happen on your device — nothing is uploaded, which is exactly what you want for IDs or contracts.
Can I scan several pages into one PDF?
Yes. Add pages one by one — each is cropped and straightened — and download a single PDF at the end.
What if the edges are not detected correctly?
Drag the four corner handles to frame the document yourself; the straightening then uses your corners. Low-contrast backgrounds (white paper on a white table) are the hardest case.
