Contact Form 7 Image Captcha


Add an SVG image captcha and honeypot to your contact form 7 form by adding the shortcode [cf7ic] to the form editor where you want the captcha to appear. This CAPTCHA is GDPR compliant and does not slow down your site with additional header requests like Google’s ReCAPTCHA.

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

Currently you need to have the CAPTCHA on the form in order for the form to send. To display a form without the CAPTCHA simply add [hidden kc_captcha "kc_human"] to your form.


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.

Preguntas frecuentes

¿Como añades el captcha de imagen a los formularios?

Simplemente añade este shortcode [cf7ic] a tu formulario de contacto

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.

i really like this plugin, but honestly: add that important notice about kc_human TO THE TOP of your description! I only inserted cf7ic in one form, and didnt wantet the other forms to be touched! guess what? none of the other forms worked and without seeing and knowing of that nessessary addition about kc_human I didnt check all other forms. OK maby it was my fault, but this plugin should make it easy and not a BAD IDEA !

This plugin has been an excellent alternative for our agency after making the decision to ditch Google's recaptcha. This plugin + Conditional fields (to only show image captcha if someone has filled out required fields) = beautiful forms that are 100% spam free. Would definitely recommend!

This plugin so far seems to be working very well. I appreciate the fact that it is very unobtrusive and not as labor-intensive to solve such as Google's image Re-Captcha, which not only requires complex configurations, but is something of a nuisance. Simple, elegant, and it works.
