How MimiFile identifies a file
MimiFile compares signatures, container structure, text structure and format-specific markers. The filename extension is treated as a hint, not as proof.
Drop a file to determine what it really is. MimiFile checks content evidence first, explains the result and routes supported formats to the right editor.

The default identification reads bounded slices of the file in your browser. It does not upload the file. Uploading starts only when you choose a server-backed MimiFile tool.
MimiFile does not execute files during identification and never labels an executable as safe simply because its format was recognized.
Use the file identifier when the extension is missing, unfamiliar or does not appear to match the file. MimiFile inspects recognized file information so you can understand the likely format before choosing a compatible conversion or tool. Identification is a diagnostic step; changing an extension alone does not rewrite the file.
A filename suffix is useful context but can be missing or wrong. Identification should be based on the file information the tool can recognize rather than on a rename alone.
Once the format is recognized, use a supported source-to-target route or focused tool when MimiFile offers one for that file type.
A file can remain unidentified because its format is unsupported, uncommon or ambiguous. That result does not by itself prove that the file is corrupt.
The identifier is intended to inspect the file rather than depend only on the filename extension, so it can be useful when the suffix is missing or appears inconsistent.
No. Renaming changes the filename, not the underlying file structure. Use a real conversion when another format is required.
Not necessarily. The format may simply be unsupported or ambiguous. Keep the original file and use a format-specific application when necessary.
