Om dette verktøyet

The MHT Viewer renders and analyzes single-file web archives directly in the browser. It reconstructs the original HTML surface from the MHT/MHTML payload, exposing embedded resources and metadata without modifying the source.
Conceptually, it decodes MIME parts, resolves resource links, and assembles a faithful in-browser representation. It emphasizes non-destructive inspection so engineers can verify integrity, recapture assets, or prepare archives for long-term storage.
The tool targets developers, QA teams, historians, and digital archivists who need quick access to archived content, without server dependency. Its core value lies in in-context rendering, asset enumeration, and easy export of extracted items for downstream workflows.
Core features include in-browser rendering, resource listing, size and type reporting, and non-destructive export options. Use cases span archival QA, compliance checks, content migration, and documentation of web-history artifacts.

Frequently Asked Questions

Finn raske svar

Which formats are supported?

The tool supports MHT and MHTML single-file web archives. It does not parse plain HTML, ZIP, or other archive formats. If an input contains mixed formats, the tool will attempt to recover the MHT content and surface available parts; otherwise it will fail gracefully.

Can I extract embedded resources?

Yes. The tool enumerates embedded assets such as images, scripts, and stylesheets; users can archive or download selected items. Extraction preserves original MIME types and filenames, allowing offline reuse or revalidation of archived content.

Is rendering done in the browser?

Rendering is client-side within the browser sandbox. No server processing is required; the tool decodes and reconstructs the document locally. If external resources are blocked by user settings, rendering may show placeholders instead of remote assets.

Are there size limits or performance considerations?

Large MHT files with many embedded resources may impact memory usage and rendering time. The tool processes content progressively when possible and will report resource counts and total sizes to help manage expectations.
