About this utility
How to use MHTML Web Archive Inspector
Inspect multipart MHTML resources, content locations, encodings, media types, and active-markup signals without rendering them.
What to provide
Drop a saved web page archive. URLs and embedded resources remain inert and are never fetched.
- Choose or drag the local file into the clearly labeled drop area.
- Review the input and the clearly labeled output behavior.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
A MIME-part table with locations, media types, transfer encodings, sizes, and active-content warnings.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- All input and output remains in this browser tab and is never uploaded or saved. This inspector does not reproduce browser layout, decode every MIME edge case, or establish whether archived content is trustworthy.
