10 Best Input Mask Plugins In JavaScript (2026 Update)
When you're creating a user-friendly HTML form on an email subscription, sign-up, or payment page to engage users and to improve the conversion rate, you might need an input mask plugin to simplify the task.
What Is Input Mask?
An input mask is a method by which a large variety of input errors can be eliminated. It simply cleans up the user-input with validations, formatting and data-types.
Suppose when you enter a phone number (e.g., +1 222-333-4444) in the input field, you would like the field to auto format the characters in '+1 NXX-NXX-XXXX' format while typing. The input mask plugin is designed for this purpose.
The Best Input Mask JS Libraries and jQuery Plugins
In the world of web development, there are a number of things you will want to make your life easier. One of these is handling input masking to get users to put in data that makes sense for you.
Input mask works by using a set of rules to create a mask for your input fields. This means a user will fill in information that makes sense instead of just typing gibberish.
Input mask can be super helpful when it comes to handling a registration form. You don't want users putting in anything in the name and email fields, for example. By using an input mask plugin, you can prevent this from happening.
In this blog post, you will find the 10 best jQuery Plugins & Vanilla JavaScript libraries for currency/date/time/phone input fields to restrict user input to a specific pattern and mask data entry in a specific format while typing. Have fun!

Input Mask FAQs
Can an HTML input pattern replace a JavaScript input mask?
The HTML pattern attribute can check a field against a regular expression during constraint validation. It does not insert parentheses, spaces, or separators as someone types. Live formatting requires JavaScript or another input-handling solution.
Does an input mask validate the value?
A completed mask only establishes that the entered characters follow its formatting rules. Dates, phone numbers, payment details, and other submitted values need appropriate validation in the application and on the server.
How do I get the unmasked value for form submission?
Use a library API that exposes the raw value, such as Inputmask's unmasking methods or imaskjs's unmaskedValue. Check the library's behavior before submission because the DOM input value may contain formatting characters.
