ZigZag Image Captcha for Contact Form 7 adds a powerful, image-based captcha field designed to protect your forms from spam and bots.
The plugin generates a
zig-zag distorted captcha image with background noise, dots, lines, and randomized angles — making it extremely difficult for automated bots to solve.
It integrates seamlessly with
Contact Form 7, works fully with
AJAX submissions, and displays
native CF7 validation errors.
