Preview Ninja allows you to safely view potentially dangerous
attachments that you may receive via email or find while browing the web.
When you upload a document, we conduct a multi-step safety check process to detect
common attacks. The document is then converted from any of hundreds of supported
file formats into a plain image file. This step ensures your computer never has to
"parse" or try to decode the file and avoids any software bugs that may be
exploited by bad guys.
