Chrome Gets MHTML Support – Save and View Files in .mht Format

Recently WebKit added support for MHTML and Chrome has incorporated it too, since webkit is used in Chrome too.”Enabling MHTML reading on the Chrome side now that the WebKit patchadding support for MHTML landed in WebKit.That is necessary for the MHTML layout tests to pass.” says a recent commit in Chromium.




What is MHTML

“MHTML, short for MIME HTML, is a web page archive format used to combine resources that are typically represented by external links (such as images, Flash animations, Java applets, audio files) together with HTML code into a single file.” wiki says.

Have you ever tried saving a webpage ? The file will save as .html and then a folder will be created along with it which will have all files from that web page, say, images and other graphics. Can this be saved as a single file ? Yes, that is our MHTML, with a .mht extension.

MHTML Support in Modern Browsers

IE : The .mht format was introduced in 1999 with Internet Explorer 5. In Internet Explorer 8 and Internet Explorer 9 Beta, the default saving format for the “Save as” function is MHTML.

Opera : Supports this from v.9

Firefox : Mozilla Firefox requires an extension to be installed to read and write MHT files

Safari : Does not support .mht as of now. However, the feature is added to webkit now, so we will soon see Safari supporting this file format.

    I’ve been wanting this feature in Chrome for a long time. I’ve been using an extension to save as one file–does a decent job but not able to view in all other browsers.

    From HTML to MHTML? Too much change for a girl missing from blogosphere for a few days now 😀

    I don’t get it. Should I re-install my browser, will they offer it as an update, or what? I’m using version 11.0.696.71 and it doesn’t support saving as or viewing .mht files.
    I have sh*tload of saved documents as .mht (since before I started to use Chrome), would find this new feature extremely helpful!

    So when exactly is this rolling down the line? I’m using 12.0.742.91 beta-m and i’m not seeing this anywhere…?

    I’m using version 13 stable and i’m not seeing this anywhere! 🙁

    I am using latest dev chromium (15.x) and it can not view mht files. Seems like everyone’s shouting about it but no one adds this function into code.

    Web browsers need an easy function to combine multiple web pages into a single MHTML, so you could do as much as archive a whole site. How about “Add to existing MHTML” ?

    How is this done exactly in chrome 15? I can not see an option to do it. Did the author try it – then please tell us, how you saved or open mhtml files, thanks!

    Google Chrome is up to date (16.0.912.75)

    And still no trace about this (so!) needed feature… And, to top it off, you (and many other blogs) get my hopes up for nothing 🙁

    Why haven’t any of the questions, about when this option will be available, been answered? A year and a half has gone by and I still do not see any option to use Chrome for MHTML docs. I hate having to use IE for anything but don’t seem to have any other choice.

    I think the website should be renamed to chromemadeupstory. And the headline “People Love These Articles !!” to “People No Longer Love These Articles As There is No One Here to Follow Up And Answer Questions!!”

    It’s not working !!! Nasty developers doesn’t support standard forcing me to use Opera as all my web pages stored in mht and i don’t use IE ! Standard mht should be supported by default in all browsers in options ”saving as mht” period and no philosofing tutoring and messing around ! Who fuck who here ??? Tons of useless developed extensions but standard is not supported !!! I don’t want it as extensions as don’t work always, i want to be supported by default !!!! Nasty developers ! Saving as html is pure hard drive polluting !!! When do they hear the voice of user ??? Some things simply are just to be there/here by default and not to be asked and prayed for !!!

  • steve 06/11/2013, 12:21 am

    Does not work !!!! Extension does nothing !!!! Who the hell has idea to save web page as tons of files ??? And no uniform standardized solution as to day ! The only browser that support single web page without extension and working is Opera on Presto engine !!! No other browser offers save complete web page !!! Why ?????????????????
