Managing a lot of scanned documents? Sometimes the sheer number can present a problem. In your case, your scan resulted in a file too big to email. The result of a scan is not a simple document or text file format.

I do this with credit card receipts all the time.Ī camera’s image can be quite large, depending on a number of different factors, and a scan is no different. Indeed, many smartphones now have apps for exactly that purpose: point the device’s camera at a document, snap a photo, and you’ve “scanned” it. Scanning results in a pictureĪs I said, scanning a document is almost exactly like taking a picture of the piece of paper with your camera. That simply takes more data to represent. The difference is simple: while the text can be represented by eight bytes, each of which represents one character in the string, a picture is a collection of information that describes each pixel in an image - in this case, a 133×40 image, which contains 5,320 pixels. That picture - a “.png” file in this case - is 2,431 bytes in size, over 300 times the size of what was needed to represent the text. That’s exactly eight bytes: one for each of the letters, one for the space, and one for the exclamation point. Options to make the resulting file smaller: use OCR to return only the text found in the picture, scan at a lower resolution, or save. Scanning is the equivalent of taking a photograph of a document.
