Contact Form 7 Image Captcha


Add an SVG image captcha and honeypot to your contact form 7 form. This CAPTCHA is GDPR compliant and becuase the images are inline SVG’s, this plugin will not slow down your site with additional header requests like Google’s ReCAPTCHA.

Directions [PLEASE READ]

Add the shortcode [cf7ic] to the form editor where you want the captcha to appear.

As of version 3.2.0, Contact Form 7 Conditional Fields is now fully supported! You no longer need to add [hidden kc_captcha "kc_human"] to your forms that do not include the [cf7ic] shortcode.

All versions in 3.1.#, require that you add [hidden kc_captcha "kc_human"] to the form if that form does not include the [cf7ic] shortcode, otherwise those forms will not submit.

You can hide the CAPTCHA until a user interacts with the form, by adding „toggle“ to the shortcode.
[cf7ic „toggle“]


Version 3.0.0 uses SVG’s instead of font icons, I have tested the changes to make sure the update would not cause any noticeable changes, however if you notice any issues, please let me know. That said, for those who have added their own custom CSS styling, you may need to update your css to account for the icon change.

We also have a Gravity Forms Image Captcha which is only available at our online store.

Časté dotazy

Jak přidat ověření obrázkem do formulářů ?

Na váš kontaktní formulář jednoduše přidejte kód [cf7ic]

How do you use the toggle feature?

To make it so the CAPTCHA only shows when the form is being filled out, add „toggle“ to the shortcode [cf7ic "toggle"] in your contact form.

Toggle is not working

The most likely reason the toggle is not working is because the double quotes around the word toggle has been changed to „smart quotes“, meaning that they are opening and closing quotation marks and not the verticle lines.

To fix, simply delete the quotes and re-add them with your keyboard – do not copy and paste.

Totally like how user friendly and effective the icon quiz is designed. I can also recommend the pro version which offers more options and features to make it a perfect fit for your website. Great service on top of that, thank you for your quick reply on my request.

After a deluge of spam recently, I almost had to settle for Google ReCaptcha. But the ReCaptcha scripts are not efficient. The image captcha is a perfect solution to the spam problem, being easy and fast to use.

Completely eliminated the ever increasing deluge of Contact Form 7 spam without putting humans off with complicated pictures or equations to solve. Simple, effective, got rid of a major headache. Perfect, thank you!

  • NEW: Full compatability for “Contact Form 7 Conditional Fields” by Jules Colle. Conditional Fields had been an ongoing issue for this plugin for a while now due to how the Conditional Fields plugin performed form validations, however I was finally able to come up with a solution that will allow this plugin to function normally with Conditional Fields installed. You no longer need to include [hidden kc_captcha „kc_human“] to your forms if the [cf7ic] shortcode is not included.


  • Updated German (de) translation


  • Updated Spanish (es) MO file

  • Added Portuguese (Portugal) translation


  • Added additional css to prevent themes from changing the layout of the icons in the CAPTCHA
