Convert MHTML to ADR

Understanding mhtml and adr file formats

MHTML (MIME HTML) is a web page archive format that saves HTML code, images, and other resources into a single file, typically with a .mhtml or .mht extension. It is commonly used for saving complete web pages for offline viewing.

ADR files are associated with Opera browser's bookmark system. An .adr file stores bookmarks and their folder structure in a plain text format, used primarily by older versions of Opera.

Can you convert mhtml to adr directly?

There is no direct conversion between MHTML and ADR formats, as they serve different purposes: MHTML archives web content, while ADR stores bookmark data. However, you can extract URLs from an MHTML file and then create an ADR file containing those URLs as bookmarks.

How to extract URLs from mhtml and create an adr file

1. Open the MHTML file in a web browser (such as Chrome or Internet Explorer).
2. Copy the URLs you wish to bookmark from the page content or links.
3. Create a new ADR file using a text editor (like Notepad).
4. Follow the ADR file structure. For example:
   

   #FOLDER
   	NAME=My Bookmarks
   	ID=1234567890
   	UNIQUEID=1234567890
   #URL
   	NAME=Example
   	URL=https://www.example.com
       

5. Paste the URLs into the ADR file, following the format above for each bookmark.
6. Save the file with a .adr extension.

Recommended software for the process

• Web browser (Chrome, Edge, or Internet Explorer) to open MHTML files.
• Notepad++ or any advanced text editor for editing and creating ADR files.
• Opera (legacy versions) to import and use ADR bookmark files.

Automating the process

If you have many URLs to extract, consider using a tool like Python with the BeautifulSoup library to parse the MHTML file and extract all links automatically. Then, you can script the creation of an ADR file by formatting the extracted URLs accordingly.

Summary

While there is no one-click converter for MHTML to ADR, you can manually or programmatically extract URLs from an MHTML file and format them into an ADR file for use with Opera bookmarks. Notepad++ and Python are the best tools for this workflow.
