How to scan documents from your smartphone

you need to scan a document, but do not want to invest in a machine dedicated to this? You are in the urgency for a paper to send absolutely as soon as possible? Why not use your smartphone! Thanks to this tutorial and more powerful sensors in your device, scan documents will become child’s play.


A lot of ways, the digital killed the paper entirely. It must be said that he is superior at many levels: environmentally of course, since he doesn’t kill tree. But also on the practice, while it is much easier to download a book in seconds to make the way to the shop.

Where this becomes especially true East with administrative formalities. Although digital arrives to the Government, many papers are still to receive hand-delivered, sign, scan and send by mail for more speed.

But when you are a student, or if you want to do in an emergency, for example, difficult to justify the purchase of a scanner. Why so do not use your smartphone in this case? It is quite possible, and we will show you how.


in itself, the use of this method is no prerequisite since it is based on the use of an Android app that is compatible with many devices.

However, keep in mind that this method obviously uses the sensor photo from your phone. Also, it must be a minimum performance to be able to capture a sheet. Test this method by yourself and make sure that the document is legible before sending it.

The environment in which you perform this capture is also to be taken into account. A barely lit room of course won’t give the same rendering than a room bathed in light. Also be sure to perform the scan on a neutral background to facilitate the work of enforcement.

Download CamScanner

we will therefore need a simple application: CamScanner, available for free on the Store over here:

Please note that the free version will add an advertising banner on your scan. If you do not have it, the paid version is available here at € 2.09 in limited promotion (usually€ 4.99):

test the application before any thing, but trust us: €2 will appear soon as a ridiculous amount compared to the service that the application makes you.

First launch


to launch the application, you will be able to create an account in order to online backup your scans for example. This step is optional, as we will not address it in this tutorial. It’s your choice.

You can click “use now” to skip this step. Once in the interface, CamScanner will ask you to allow it to access the storage: agree. Then click on the camera icon, and agree a new its application for authorization.

Use CamScanner


so here you are in the interface of the application scan. Please have a background contrasting with your worksheet to help the application to recognize it, and be in a well-lit room.

On your screen, tap the sheet you want to scan in order to put autofocus on it. Bottom right, these icons allow you to choose between a single scan or a scan batch (if you want to scan a document of several sheets in one).

Try to be as as possible above your document, but don’t be afraid however: enforcement is so well made that even when the angle does not match, it will give the whole flat as in the example above.

Edit the capture


base, CamScanner performance are quite staggering. But if he had made a mistake automatically cropping a photo, or if you would like to edit the contrast of your scan, press the icon surrounded by a red square in the preview (see above).

The first window will allow you to retouch the automatic clipping of your worksheet. So, if you think that the application has trimmed part of your document, you can find it here and edit as seems you the clipping.

Once this is done, you’ll find yourself in CamScanner-editing interface. At the top of the application settings are available: Auto, which will edit for you the contrast and the brightness of the document to make it more readable as possible, original that will keep the source, low quality and high quality whose names are quite misleading in itself.

Note that at the bottom of the interface, you also have the possibility to switch the image on the left or the right, to find the document in its natural sense of reading.

By pressing the icon of sliders, you will have access to much more accurate settings: those of contrast, brightness, and finally details. Make sure well manage your balance between brightness and contrast, so that the document is readable without to erase elements of the document.

And this is, here you are ready to send it to your bank, to the State or whatever! You didn’t think that your smartphone could be used so is not it? These small devices know better herself than you think!
