Sometimes when applying for jobs online, the employers ask for sending the scanned copies of the documents over the email or upload to their web site. This is usually not a problem if you are near a scanner or multi-function printer. But when you have to send the scanned documents online as soon as possible and you have no idea where to find a scanner, then it can turn into a nightmare. But if you have an Android smartphone with a camera then you are in luck. You can use your smartphone’s camera to scan and convert any documents into PDF files using the free CamScanner app.
Usually the camera scanning does not work very well. But the CamScannner app scans the documents so perfectly, that you can barely tell if they have been scanned using a camera. The quality of the scanned documents improves if your smartphones has a good quality camera of 8 megapixels or more. Having an LED flash in the smartphone camera also helps.
In the CamScanner app, you can touch the camera icon at the bottom to start scanning your documents. Place the document on a smooth surface having a color different to the document being scanned. For example, if your document is a white paper sheet, then placing it on a colored bed sheet is a good idea.
After the document is snapped, the CamScanner app automatically calculates its edges and you are given an opportunity to adjust the edges, rotate the scanned image and resize it as necessary. After this CamScanner will turn it into a rectangular scanned page and modify the brightness, contract, color etc., to make it look better. But you can also manually adjust these settings if you are not satisfied with the auto-adjustments.
Finally, as you touch the checkmark icon near the bottom edge to proceed and save it as a PDF document. You can rename the document as you wish, add a comment to it, share it with others or touch the PDF icon to open it using a PDF viewer app in your smartphone.
Verdict: CamScanner is a great app that allows you to scan any document of any size directly into a PDF file using just your Android smartphone camera. It can be very useful if you do not have a traditional scanner or you have to quickly scan something when you are away from your office or home.
