Is my uploaded MHTML file uploaded to external servers?

Yes. The archive is uploaded to the conversion server for decoding. The application does not persist uploads or output documents in a database or file store.

Can I copy text and inspect images from the MHTML viewer?

Yes. You can select, copy, and search all text content, switch to Text/Code mode, and view extracted embedded MIME images.

Does this viewer support large MHT email archives?

MHT and MHTML archives are supported up to 4 MB. The decoded output must also fit within the 4 MB download limit.
