Convert UHTML to HTML

A program may reject a UC Browser offline page because it uses the .uhtml extension instead of .html. Changing it to HTML can make the saved page easier to open, edit, archive, or publish, although the result may still depend on separately saved resources.

What the UHTML format is

In the Internet context, UHTML is a webpage-save format associated mainly with UC Browser. A saved file may contain HTML markup and may embed or reference images, stylesheets, JavaScript, and other resources captured from an offline page.

UHTML is not a separate web markup language. Many files are ordinary HTML source saved with a nonstandard extension, but some versions or files may use application-specific packaging or encoding. The extension alone does not prove which structure a particular file uses.

What the HTML format is

HTML is the standard markup language used by web browsers to represent webpage structure. An .html file can be opened in Chrome, Firefox, Edge, Safari, and text editors such as Visual Studio Code or Notepad++, and can be placed on a web server without a format-specific application.

HTML is preferable when the destination software does not recognize .uhtml, when the markup must be edited, or when the saved page needs to be inspected and republished.

How to convert UHTML to HTML

1. Make a copy of the original file, such as page.uhtml.
2. Open the copy in Visual Studio Code, Notepad++, or another text editor. If it contains readable markup beginning with elements such as <!DOCTYPE html>, <html>, or <head>, it is already HTML content.
3. Rename the copy to page.html. In Windows File Explorer, enable View → Show → File name extensions before renaming, then confirm the extension-change warning. On macOS or Linux, rename the suffix in Finder or with mv page.uhtml page.html.
4. Open the renamed file in a browser by dragging it into a window or using the browser's file-open command. Open it in an editor when the source needs correction.
5. If images, styles, or scripts are missing, keep the HTML file beside the resource folder produced by UC Browser and preserve the original relative paths in src and href attributes. Do not rename or move referenced resources unless you also update those paths.

Renaming is sufficient when the file is valid HTML with a different suffix; it does not transform the content. If the editor displays binary or compressed data, inspect a copy with an archive utility such as 7-Zip and open the original in the UC Browser version that created it. If that application can export or resave the page as HTML, use that output; otherwise there is no dependable generic UHTML conversion engine.

Quality and compatibility limits

An offline save is a snapshot, not a complete copy of a live website. Server-side functions, login sessions, forms, advertisements, network APIs, streaming media, web fonts, and scripts requiring the original domain may fail after renaming.

Some saved pages keep resources embedded or use application-specific references, so valid HTML can still display without its images or styles. Use the browser's developer tools or search the source for broken src, href, and stylesheet paths. A page that opens locally may also behave differently when hosted because browsers apply local-file security restrictions.

No widely established online service reliably converts arbitrary UC Browser UHTML files. Generic HTML converters are unnecessary for text-based files and may damage embedded resources; uploading an offline page can also disclose cookies, private content, or saved URLs. Use local renaming or local inspection unless an online service explicitly documents support for this UHTML variant.
