Free Online CAPTCHA Image Generator
Features
Custom text
Type any text you want and it is rendered onto the CAPTCHA image instantly — letters, numbers or mixed characters.
Distortion controls
Adjust the noise level, wave intensity and rotation range to make the image as readable or as scrambled as you need.
Emoji noise
Scatter emojis between characters and tune their size, adding an extra layer of noise that plain OCR struggles with.
Color and size control
Pick the text color and background color, set the font size, then download the result as a PNG image.
Runs in your browser
Rendering happens on a canvas locally in your browser — no account, no upload, no server round trip.
