If you have large piles of paper stacking up on your desk, then a document scanner can help eliminate that clutter by preserving it all digitally. However, not all document scanners are created equal. Some excel at receipts and small documents, while others specialize at digitizing longer documents quickly and effortlessly. To cut through the confusion, we've laid out a step-by-step buying guide to help you choose the best model for you.

Step 1: What Are You Scanning?

Our review focuses on document scanners, which can generally handle paper documents, receipts, and ID cards. If you'll mostly be scanning these types of things, read on.

If you're looking to digitize a bunch of old photos, you're going to want a dedicated photo scanner. These models are generally bed-style scanners (so you don't bend the original photograph) and are better optimized for high resolution and more accurate color reproduction, not lengthy documents.

Step 2: How Often/Much Do You Scan?

The volume and type of scanning jobs that you will perform during a normal day will largely dictate which model you should get. If you tend to scan only a few documents or receipts a week, you are best off using a cheap smartphone app like the Scanner Pro App. This app uses the camera on your smartphone to create high-quality PDFs that can be shared via email, text, or Bluetooth. It also performs optical character recognition well, making your documents searchable. If you tend to scan a few 10ish page long documents a week, a portable model like the Brother DS-620 Mobile adds a level of convenience over having to take photos of each individual page. You just have to feed each page you want to scan into the scanner, and it does the rest.

If you scan dozens of pages every day, it is worth investing in a high-end model like the Fujitsu iX1600 or the Epson WorkForce ES-400. High-end models can zip through documents in a flash and often have automatic document feeders, so you don't have to load the pages individually. You'll want to make sure you have a document feeder that is large enough for the types of documents you tend to scan, as their capacities range from 10-pages to 80-pages.

Step 3: Do You Need Optical Character Recognition? Probably

Optical Character Recognition (OCR) is a software program that recognizes text, resulting in PDFs with searchable text. Even if you aren't planning to copy and paste large sections of text from the documents you scan, OCR can help keep you organized because it allows you to search your hard drive for documents based on the text they contain (i.e., find every document that contains a certain credit card number). All but one of the models we tested features OCR, though some tend to be more accurate than others. You can look to the Software section of our reviews for more information on a specific model's OCR capabilities and performance.

Step 4: Does Resolution Matter?

For text documents, you really don't need to worry about resolution. All but the smallest of text is perfectly readable at a 300 dpi (dots per inch) resolution. All of the scanners we tested provide at least 600 dpi, double the minimum acceptable quality.

Step 5: Think About Compatability

Almost all scanners come with PC-compatible software, but some of them don't play so nicely with Mac operating systems. While you can generally find 3rd party drivers for models that aren't inherently Mac friendly, this often comes at the expense of some level of functionality. If you're a Mac user, it's better to stick with a model that comes with Mac software in the box.
