Our File MIME Type Checker analyzes any uploaded file to determine its true file type, size, and last modification date based on content analysis rather than just the file extension. This tool examines the actual binary signature and structure of files to identify their genuine format according to MIME (Multipurpose Internet Mail Extensions) standards, which define file types across the internet. Developers use this information when troubleshooting file upload systems, verifying file integrity, or implementing content validation. Security professionals rely on MIME type checking to verify that files are what they claim to be, helping prevent certain types of attacks involving disguised file formats. The tool provides essential metadata including file size in bytes, actual content type, and the file's last modification timestamp. Whether you're debugging upload functionality, validating file contents, or simply need to verify a file's true format, this checker provides accurate file analysis without requiring specialized technical knowledge.
