Frequently Asked Questions
Why does a file’s extension sometimes not match its real format?
Files are occasionally renamed or saved with a mismatched extension; this tool reads the actual file data to identify the true format regardless of what the filename says.
What information does this tool show?
The real format, pixel width and height, color space, whether it has an alpha (transparency) channel, and the file size.
Does this modify or re-save my file?
No — it only reads and reports information; your file is untouched.
Can I check multiple files at once?
No — one file at a time.
