I would like to know how to do that by choosing the file to upload it to filter by native .pdf extension html or by JS, Jquery.
Using the type="file" it brings all the files.
<!DOCTYPE html>
<html>
<body>
<h1>Selecione o arquivo PDF:</h1>
<h3>Selecione o PDF:</h3>
<form action="/action_page.php">
<input type="file" name="myFile"><br><br>
</form>
</body>
</html>
