Format Verifier FAQs

A file's extension (like .jpg) can be easily changed and might not represent the file's actual format. This can cause errors when you try to open or process the file. Our verifier will read the file's "magic numbers"—a unique signature at the start of the file—to tell you its true type, ensuring you know exactly what you're working with.

A MIME type is a standard way to identify the format of a file on the internet. For example, `image/jpeg` is the MIME type for a JPEG image. Our tool will show you the correct MIME type for your file.

Yes, absolutely. Like all our tools, the Image Format Verifier is free and processes everything securely in your browser. Your files are never uploaded to our servers, so your privacy is protected.
