5 Excellent Free PDF Scanners for Android

The high-resolution cameras on our smartphones are being put to a myriad of useful purposes today. We’re even at a point where if manufacturer support for the scanner you’ve been using for years fails to keep up with operating system upgrades, you can forget it and use your smartphone instead.

An Android PDF scanner for a phone or tablet can provide the scanning functions for which you used to have to rely on having a desktop scanner. They enable you to quickly scan any paper document and convert it to a PDF file. You’ll have digital records of receipts, forms that you’ve had to complete, and all sorts of paper documents that take up unnecessary physical space. You’ll find it faster and many scanners now available even have OCR support. Best of all, you’ll be able to find a free Android PDF scanner to meet your needs.

The applications scan documents and export them to industry-standard PDF format and, in most cases, pages can be added or deleted. You can save files to or access documents from cloud facilities from the application, which also provide enhancing and trimming functions. Some of the best on the market include the following apps.
