The HTML accept attribute specifies the type of file that the server accepts. The submission is possible through a file upload.
You can only use this attribute on the <input> element. It is only used with <input type="file">.
The accept attribute must not be used as a validation tool. File uploads must be validated on the server.
<input accept="file_extension | audio/* | video/* | image/* | media_type">
Example of the HTML accept attribute:
<html> <head> <title>Title of the document</title> </head> <body> <form action="/form/submit" method="post"> <input type="file" name="Image" accept="image/*"> <input type="submit"> </form> </body> </html>
