Page Utilities

This page gathers three free tools for completing a page or a link. UTM Constructor adds a measurable campaign to an address, Escape an expression protects RegExp special characters, and Email obfuscator turns an address into HTML entities. These utilities suit marketing teams, developers, and writers who prepare links or protect content. No sign-up is required, and everything stays in your browser.

Use UTM Constructor if you need to tag an address for campaign tracking. Choose Escape an expression when you insert text into a RegExp pattern. Pick Email obfuscator to turn an address into HTML entities. Each tool answers a precise need and can be used alone. They are free and require no sign-up.

How to use

  1. To track a campaign, start with UTM Constructor to add measurable parameters to an address.
  2. If a text must enter a pattern, use Escape an expression to protect RegExp special characters.
  3. To limit automated collection, choose Email obfuscator and turn the address into HTML entities before publishing it.
  4. Read each result before copying it into your page, because UTM Constructor, Escape an expression, and Email obfuscator change different elements.

How can I protect an email address?

Can I use UTM Constructor and Email obfuscator on the same page?

What should I check after escaping an expression?

Read the result provided by Escape an expression and test it in your pattern. Check that special characters are no longer treated as commands. If the pattern works, copy the resulting value into your code.
