Morse Code Image Generator

Sometimes a message needs to travel as an image. A morse code image generator turns any text into the classic dots-and-dashes signal rendered as a clean PNG — useful for worksheets, puzzles, social posts, signage, or any place where you want morse code as a visual rather than a string.

OpenToolLab's morse image generator converts text to International Morse code and renders it as a PNG image. Letters become dots and dashes, letters are separated by a standard three-unit gap, and words by a wider seven-unit gap, preserving the real timing of the code.

The image is rendered locally on a canvas, so it is crisp at any size and downloads instantly as a PNG. You control the look: choose Small, Medium, Large, or XL dots and Black, Blue, Red, or Green signal colors to match your document, brand, or classroom materials.

The tool is also a full two-way translator. Paste dots and dashes into Morse → Text mode to decode them back into readable English, or type text to see it as code before generating the image. Both directions follow the International Morse standard, including digits and punctuation.

Privacy is a core guarantee. The image is generated entirely in your browser — your text never touches a server. Open the DevTools Network tab while rendering and you will see zero requests.

Because rendering happens locally, the tool is instant, free, and works offline. There are no watermarks, no upload steps, and no limits on how many images you generate.

OpenToolLab is a completely free morse code image generator with no signup and no premium tier. Whether you are preparing a classroom worksheet, making a puzzle, or sharing a hidden message, this tool gives you a clean, downloadable morse image — privately and at no cost.
