Save Webpages Offline As MHTML

The “Save Webpages Offline As MHTML” is a very small but useful extension for Google Chrome and other supported browsers. Users can install it from this link and start saving web pages offline as MHTML file.

How To Use?

Once you have installed it from the above link, you should notice its icon on the toolbar. Click on this toolbar button, and extension would save the current tab as MHTML file on your computer.

chrome mhtml

Keyboard Shortcut

Alternatively, you can also use extension’s keyboard shortcut command: Alt + S. Make sure this keys combination doesn’t conflict with any other extension or system command on your computer. You can always change this combination and set a different keys combination by following this tutorial.

Context Menu Option

You can also save a web page by using extension’s option in the context menu (right click menu). For this, right click anywhere on a web page and select the option “Save page as MHTML” as shown in the following screenshot:


What is MHTML?

It is a file format to archive web pages. When you save an online web page to your computer, its components like CSS files, images etc. are generally saved in a folder which is linked with the saved HTML document. But with MHTML, all such components are combined and saved as a single MHTML file along with the HTML document. This simplifies managing and sharing saved web pages. MHTML files can be opened by  Google Chrome, Internet Explorer and many other browsers. Firefox doesn’t support this file format. Read more about MHTML on Wikipedia.

chrome mhtml

This Save Webpages offline As MHTML extension is very useful if you are looking for a simple and quick way to save offline copies of web pages. You can take backup of these saved MHTML files on cloud storage services like Dropbox and Google Drive – and refer them in future if required. This extension is highly recommended for students, researchers, developers and other professionals.

Firefox Version?

AFAIK Firefox doesn’t support MHTML format, so there is no point of creating Firefox extension. Firefox users should save web pages by using the usual Ctrl + S keyboard command, which saves web pages as HTML file.

  1. Ignore my previous comment, it turns out that the download option in Vivaldi was set to default, so it didn’t prompt for where to download the saved file.

    It’s all good and works fine

  2. Haven’t tried in a short while, but now I find that this doesn’t work in the Vivaldi web browser. It still seems to work in many other browsers, just not Vivaldi any more, whereas it used to work fine.

    What has changed?

  3. It worked perfectly… once. But when I tried again a few hours later, it suddenly won’t work at all no matter what I do. The keyboard shortcut doesn’t work, clicking the icon does nothing, and even choosing the option from the right-click context menu does nothing. I’ve disabled and re-enabled the extension, but that didn’t fix it. Completely uninstalling and re-installing it did absolutely nothing, as well. What the heck?!

  4. Hi,

    greate extension. But I have problem with saving a Microsoft Teams channel.

    It does not save the complete channel, but only a few pages, and it doesn’t save images.

    If it could save complete Teams channels and chats without limits it would be great tool so export information from Teams.


  5. very nice extension, 2 requests:
    can you add a silent mode? – no file requester for file name each time?
    can it save the pages with filename made of host-date-time-title?

  6. Excelente extensão!
    Existe uma maneira de juntar todos os arquivos salvos em um único arquivo?

  7. But does it save an entire website, not only a page, so one does not have to go through every single page to save them?

  8. Best MHTML downloader extension for Chrome browser. Works smoothly. Use it everyday for my research work and other stuff.
    My only concern with MHTML is that it’s not widely supported, like we can’t see file previews directly in Gmail app similar to PDF files.

  9. Thanks for this extension, I use it everyday. Could you please explain how can I convert mhtml to HTML or PDF? Sometimes, I have to use Firefox and MHTML is not supported in that.

  10. Please Can you add “save to another location” as i dont keep my stuff in Downloads folder.

    That would be awesome


  11. Works nicely. Thanks!

    My only gripe is that it automaticcally saves to the Downloads folder – having a file selector open instead, to choose case by case, would make it more versatile.

  12. I’ve found the solution. the “Chrono Download Manager” was the problem. I’ve disbled it and the txt problem’s gone. I think it’s time to find another download manager

  13. Thanks Arpit for your explanation. I was facing the same issue as Raidel reported, so I visited this page to report, and saw your reply. I tried this extension with no other extension installed … and it worked perfectly!

    I agree that some third-party extension is breaking this. Well a workaround for those seeing .txt extension -> manually change .txt to .mhtml when it prompts to save the file – and it will work without any problem.

  14. @Raidel: It looks like some other extension is interfering with it. Please try after disabling other extensions, and it should work fine.

  15. Hello very good, I have been using it for a long time but for a few days now it is saving me the pages in .txt format someone knows why this happens thanks

  16. Thanks for this useful extension. I was badly missing save as mht chrome feature. Earlier it was available in Chrome through a chrome flag –save-page-as-mhtml , but it has been removed now.

    Tried pagearchiver and singlefile chrome extensions as well, but they didn’t work as expected. finally got your extension, and it is super handy. Thanks

  17. With the new versions of chromium and derivatives you can no longer activate the mhtml from flags. Luckily there is this great extension, THANKS.

  18. @Arpit Is there a way you could add this extension to the contextual menu within Chrome? Sometimes I have trouble quickly aligning the cursor onto the (relatively) tiny icon in the top of the browser window; it would be faster and more reliable (for me, at least) to call the extension from the contextual menu, if possible.

    Great extension, though. It has quickly become indispensable to me.

  19. @Mike @MDESGeezer We have removed timestamp in the latest version, as this was requested by many users.

  20. Can you guys make a toggle switch or something to disable adding the timestamp to the filenames?

  21. Nice, what would be nice would be options for you to set the download directory, wildcard filenames, perhaps a timer that does this every x seconds,

  22. Excellent extension!

    Thank you very much.

    I was using “Save As MHTML” but I found out that “Save Webpages Offline As MHTML” also includes the page headline and the date and hour of MHT downloading. It’s great!

    What a pity that you can not make a version for Firefox ( which had the formidable “Mozilla Archive Format” and now in Quantum only supports the pathetic “Save Page We” ); and I think too it’s a horrible shame that Microsoft has not implemented something similar to “Save Webpages Offline As MHTML” for its browser Edge: Why to develop a good browser if it does not allow the user to save in an efficient way pages of the website?

    Please, do not faint in your magnificent work spirit.

    For now and forever I wish you the best successes.

  23. thank you for the good job, it works perfectly, and perhaps i should add that if you want to convert the mhtml back to html, just open it in microsoft word and save it as html
