Do you have tons of documents or books taking up space home? Got no room for new books and don't want to throw away old ones? This is where a scanner can help. Not only can you convert your documents and books into electronic files to free up space at home, but you can also read them on a special mobile app. There are many scanners on the market today, so how to choose the right one? Here’s a guide to help you!

1. Type

There are three main types. Choose according to the following tips and your personal needs.

2. Resolution

The higher the resolution, the more detailed the image quality. A resolution of 300dpi is best for text-only scans, while 600dpi is more suitable for images and photos. The higher the resolution, the higher the file capacity. If you are looking for more detail, choose a model with a high resolution.

3. Sensor

CCD and CIS sensors are the two main types of scanners now available. CCD sensors offer fast reading speed and high resolution for high quality images. Although CIS sensors are not as fast and detailed as CCDs, they are smaller and more affordable, which makes them a good choice for those on a budget.

4. A3 size

Generally, document scanners and platform scanners are suitable for A4 documents. For larger documents and books choose an A3-size scanner.

5. Additional features

Some scanners come with extra features such as auto-correction, residual image elimination and document background correction etc. These features solve noise and skew problems and improve work efficiency. Some models support mobile apps, making it easier for users to store scanned documents. Look for these features before you buy.
