Edges found for you

The page is found in every frame of the camera and in every photo you drop, and its four corners are set.

Flat pages

A page shot at an angle comes out straight and rectangular, in its true proportions.

Automatic capture

Hold the page steady for a moment and the picture is taken. The shutter is there too.

Shadows and uneven light are evened out. Black and white keeps thin strokes crisp.

Many pages

Take page after page. Reorder, rotate or remove them before you save.

Searchable text

Text recognition runs automatically when saving. Review the recognized text in the downloaded PDF.

Frequently asked questions

How do I scan a document to PDF?

Select Camera and point it at the page, or drop photos of the pages. Check the corners, pick a look and select Save.

Does it work without a camera?

Yes. Drop photos of documents taken with any phone or camera. The pages are found in them the same way.

Can I fix a corner?

Yes. Open Corners and drag the corner to the edge of the page. The page is made again at once.

Are my photos uploaded?

No. The camera picture and the PDF stay in your browser and never leave your device.

Is it free?

Yes. No account, no usage limits and no watermark.

Technical details

Page edges

The photo is reduced, smoothed and searched for edges. The largest four-sided outline with an edge along all of its sides is the page, then each side is placed on the full photo to a fraction of a pixel.

Flat page

A perspective transform maps the four corners to a rectangle. Its proportions come from the corners and a pinhole camera model, so an A4 page stays A4. The long side is at most 2400 pixels.

Filters

The paper brightness is estimated across the page and divided out, which removes shadows. Black and white uses an adaptive threshold over a window a sixteenth of the page wide.

Camera

The camera is asked for only when you select Camera. Its picture goes to the page and nowhere else. The torch is offered where the camera has one.
