Definition and Usage
The download attribute specifies that the target will be downloaded when a user clicks on the hyperlink.
This attribute is only used if the href attribute is set.
The value of the attribute will be the name of the downloaded file. There are no restrictions on allowed values, and the browser will automatically detect the correct file extension and add it to the file (.img, .pdf, .txt, .html, etc.).
If the value is omitted, the original filename is used.
The download attribute, if present, indicates that the author intends the hyperlink to be used for downloading a resource. The attribute may have a value; the value, if any, specifies the default filename that the author recommends for use in labeling the resource in a local file system. There are no restrictions on allowed values, but authors are cautioned that most file systems have limitations with regard to what punctuation is supported in file names, and user agents are likely to adjust file names accordingly.
The attribute can furthermore be given a value, to specify the filename that user agents are to use when storing the resource in a file system. This value can be overridden by the Content-Disposition HTTP header’s filename parameter.
lets have example, suppose your file name is mysitelogo.png but you want that whenever anyone download this file, file name change automatic like – logo.png for that you can use –
<a href="myFolder/mysitelogo.png" download="logo">Download image</a>
try this and have fun.
