Frequently Asked Questions

A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a type of challenge-response test used in computing to determine whether the user is human. It typically involves distorted text that humans can read but computer programs struggle to interpret correctly.

Using our CAPTCHA Generator is simple:
  1. Enter custom text in the input field or click the refresh button to generate a random CAPTCHA
  2. The CAPTCHA will appear in the display area with visual distortion applied
  3. You can test the CAPTCHA by entering the text in the verification field
  4. Use the download button to save the CAPTCHA as a PNG image
  5. For accessibility, use the audio button to hear the CAPTCHA text

Yes, you can download the CAPTCHA images and use them on your website or application. However, for production use, we recommend implementing a server-side CAPTCHA solution that can generate and validate CAPTCHAs dynamically, as static CAPTCHAs can be vulnerable to automated attacks once they've been solved and recorded.

Yes, our CAPTCHA Generator is completely free to use with no limitations. You can generate as many CAPTCHAs as you need without any cost or registration requirements.

A good CAPTCHA should:
  • Be easy for humans to solve but difficult for bots
  • Have sufficient visual distortion to prevent OCR (Optical Character Recognition) software from reading it
  • Be accessible with alternative options like audio CAPTCHAs
  • Not rely on cultural knowledge that might exclude some users
  • Have a reasonable level of difficulty - not so hard that it frustrates legitimate users
