Localizador de tipos MIME

Look up MIME records from the bundled mime-db 1.54.0 snapshot by MIME type, extension or file name. In file mode, read a local file’s declared browser type and the first 16 bytes to compare known signatures, then show matching extension records. Signature detection is prefix-based and the report is not proof that a file is complete or safe.

Recursos

  • Search the bundled MIME database by type, extension or file name.
  • Read a local file’s declared MIME type without uploading it.
  • Compare the first 16 bytes with known PNG, JPEG, PDF, ZIP and other signatures.
  • Export the lookup or inspection report as JSON.

Como usar

  1. Choose database lookup or local file inspection.
  2. Enter a MIME type, extension or file name, or select a file.
  3. Run the lookup and compare declared, signature and extension results.
  4. Copy or download the report and validate the file in its real processing context.
