MHTML files are notoriously redundant. If you archive the same news site every hour, 95% of the data (the logo, the CSS layout) repeats. NippySpace uses block-level deduplication. When you upload 1,000 MHTML snapshots of the same page, NippySpace stores the core template once and only the text diffs for the rest. You effectively get 1,000 archives for the price of 1.5.

The W3C has not updated the MHTML specification significantly since 2011. However, NippySpace is petitioning the Internet Engineering Task Force (IETF) for MHTML 2.0 features, including support for WebP images and AVIF compression within the MIME envelope.

Furthermore, NippySpace recently announced NippyAI Summarization. Soon, when you save an MHTML, the AI will generate a 100-word summary and store it as metadata. This means you can search for "Summary: Climate report" and instantly find the right MHTML without reading the 50-page archived webpage.

NippySpace (often associated with Nippyfile) is a file hosting service. It allows users to upload files to the cloud and share them with others via generated links. These types of services are commonly used for sharing documents, backups, or web archives.

When dealing with archived web data, security is paramount. NippySpace addresses the specific vulnerabilities of MHTML.
