HTM file contains markup code in Hypertext Markup Language format, and shares many similarities with HTML. This is a standard document file used for creating static web sites. HTM stores markup code used to display images and text. This format is very popular among website designers and developers.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the HTM file after converting to HTML5 may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from HTM to HTML5 to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting HTM to HTML5 does not meet your expectations, you can simply try to find on the Internet a different version of your file in HTM format, properly converted to a HTML5 file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file HTM the desired result was not achieved, you can try to change the format of HTM file to other than HTML5. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your HTM file converted by someone else, and the attempt to convert it to HTML5 on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the HTM file in its original format (without conversion to HTML5 file). Such a solution will be difficult to implement, but it certainly will give the best result.
