What Is an Online File Scanner?

An online file scanner is a tool that scans files for viruses and malware patterns. It is used on devices that are connected to the Internet, such as desktop computers, laptops, tablets, and smartphones. Online file scanners can scan multiple files in a single session. This is important because it saves time and resources.

One prominent online scanner is Virus Total, which is free to use and requires no download. It uses over 70 antivirus engines to scan your file. It also identifies obfuscated or polymorphic variants of malware, which are hard to detect with traditional antivirus software. It also detects a variety of malware types including trojans, worms, ransomware, backdoors, spyware, and more.

Another option is NordVPN’s free File Checker, which allows you to scan your files for threats. It identifies malware and phishing attempts, and can even help you determine whether a file is safe to download or not. It works by scanning the file in a sandbox and then displaying the results to the user.

With the Recognize Text (OCR) feature, you can convert text images in PDFs into searchable, selectable text. This is useful for creating documents that are accessible to people with visual impairments. The OCR settings in the Document Properties dialog control how text is recognized. To improve recognition accuracy, the original scanner resolution must be 72 dpi or higher. To enable PDF/A-1b compliance, select the Add Metadata option in the Document Properties dialog after scanning.
