➤How to scan documents with a smartphone: the best Android apps 🕹

How to perform scans from your Android smartphone? There are a few easy-to-use, and often free, applications for this.

The advantage of a scanner-type application is that it allows you to share files that are much smaller than photos that are also very easy to take. It takes care of automatically converting the “photographed” document to PDF format, and often adds some very practical functions. Possibility to adjust brightness and contrast, crop documents then share them on social networks and messaging services, not to mention annotation options: the options are generally numerous.

Here we focus on the range of applications available on Android. If your smartphone is from Apple, follow the link to learn how to easily scan documents with an iPhone.

How does it work?

The very principle of a scanner application on Android is quite simple: they take advantage of the quality of our mobile devices to take a photo of a document that you want to scan. Then, they are responsible for determining the edges so that they can isolate it from the bottom.

And finally, she'll work on retouching the photo so that it looks like a scanned document. Thus, the white becomes perfectly white again, the black perfectly black, and everything really passes for a scan as we did before. The great strength of a scanner application on Android will therefore be its ability to detect the edges of the document in a photo, but also to effectively transform it into a scanned page whether it is to retouch the colorimetry or even the angle. .

Very easy to use - creating an account is not mandatory - it allows you to scan color or black and white documents, adjust the level of details, search for documents by keywords and share documents from contacts who will be able to comment on them in annotations. To perform a scan, all you have to do is click on the pictogram representing a camera, then let yourself be guided. If you use the application on a regular basis, it is better to download the license (paid), which will allow you to remove advertisements and watermarks from documents.
