CHECK FILE TYPE BASED ON CONTENTS OF THE FILE
Have you ever found a file on your computer without an extension or has an incorrect extension? CheckFiletype.com helps you determine the true file type of any file based on the content of the file, not the extension. Simply use our online tool to upload the file and we will test it and show you the results.
CheckFileType does not require an e-mail or registration. The purpose of this site is to provide a quick tool to help you determine the file extension for an unrecognized or unknown filetype.
In some cases such as zip files this tool may search the contents of the archive to give you the file type of each file contained in the archive.
