In this tutorial, we will explore how the accept attribute in HTML5 functions.
What do you mean by accepting attributes in HTML5?
The accept attribute in HTML defines a restriction on the types of files that users can select from the file input dialog box. This attribute is specifically designed for <input type="file">. Its purpose is to enable browsers to display only the files that are permitted for the particular input field.
Syntax:
Example
<input accept="file_extension|audio/*|video/*|image/*">
In the syntax provided above, there is an option to specify either a file extension or a file type when selecting a file from an upload feature, like image, audio, video, etc.
Below are different instances of accept attributes in HTML 5:
Example 1:
Example
<! DOCTYPE html>
<html>
<head>
<meta charset = "utf-8">
<meta name = "viewport" content = "width=device-width, initial-scale = 1.0">

<h1> HTML5 accept attribute Example </h1>

</fieldset>
<fieldset>
<label for="select-choice"> Select Hobbies </label>
<select name = "select-choice" id = "select-choice">
<option value = "Choice 1"> - - select one - - </option>
<option value = "Choice 2"> Dancing </option>
<option value = "Choice 2"> Singing </option>
<option value = "Choice 2"> Playing </option>
<option value = "Choice 2"> Cooking </option>
</select>
</fieldset>
<p>
<label for = "imageFile"> Select some images: </label>
<input type = "file" id = "imageFile" accept = "image/*" multiple>
</p>
<button> Submit </button>
</form>
</body>
</html>
Explanation:
In the example provided earlier, we have demonstrated the application of the accept attribute by allowing only image files to be uploaded through the file input field.
Example
<input type = "file" id = "imageFile" accept = "image/*" multiple>
In this
- <input> tag is used to get the input from the user
- type="file" used to specifies the file input.
- accept parameter is used to specifies that the server accepted file types.
- "image/*" is define the input file must be image format.
- multiple attribute means we can upload multiple image files from the input dialog box.
Output:
Following is the output of this example.

Explanation:
In the previous instance, we have demonstrated the accept attribute by restricting the file input box to only allow audio files to be uploaded.
Example
<input type = "file" id = "soundFile" accept = "audio/*">
In this
- <input> tag is used to get the input from the user
- type="file" used to specifies the file input.
- accept parameter is used to specifies that the server accepted file types.
- "audio/*" is define the input file must be audio format.

</html>
Explanation:
In the demonstration provided earlier, an instance of the accept attribute was illustrated. This particular demonstration showcased the process of selecting and uploading a video file exclusively from the designated file input field.
Example
<input type = "file" id = "videoFile" accept = "video/*">
In this
- <input> tag is used to get the input from the user
- type="file" used to specifies the file input.
- accept parameter is used to specifies that the server accepted file types.
- "video/*" is define the input file must be video format.

Following is the output of this example.
