Morse Code Image Translator
Turn clear dots and dashes in a screenshot into text. Review the detected marks, fix their spacing, then copy or hear the message.

Review the detected marks.
Compare with your image. Edit a mark or add spaces between letters; use / between words.
Your image is processed on this device and is not uploaded by the tool. Best for clear, horizontal dot-and-dash images.
Get a readable image first.
Choose the signal.
Upload a PNG, JPG or WebP, drop a file, or paste a screenshot. Include the full first and last marks and enough blank space between letters and words. Avoid captions, decorative borders and unrelated text.
Adjust the picture.
Crop margins to isolate the Morse area. If the marks are light on a dark background, turn on the light-marks option. Raise or lower the threshold when faint marks disappear or the background is being picked up. Press Read image again after changing settings.
Review the draft.
The editable box shows what was recognized. Add a space between letter groups and a slash between words. The text updates as you correct the draft. Copy the English result or preview its sound; playback is limited to the first 240 Morse characters.
Visible marks, not general text recognition.
This image Morse code translator looks for connected shapes, compares their widths, groups them into horizontal lines and estimates the gaps. It then decodes that draft with the same character table as the text translator.
The method is designed for distinct dots and horizontal dashes. It does not understand arbitrary handwriting, beads, curved tattoos, blinking lights or recordings. A photograph with shadows, skewed rows or merged marks may need cropping and manual corrections, or may produce no usable result.
Character patterns and timing checked against ITU-R M.1677-1, International Morse code.
Why a plausible answer can still be wrong.
A cropped dot can disappear. Two touching dots can look like a dash. A wide gap can split one word into two. Even a draft made entirely of valid Morse characters may use the wrong boundaries.
Compare the result with your original. Use the alphabet reference for uncertain groups and the reading guide for spacing. Warnings describe detection problems; they do not certify the intended meaning of an image.
Image decoding questions.
Can it read more than one line?
Yes, for clear horizontal rows. Each detected row is separated by a word break in the draft. If one word wraps across rows, remove that slash manually.
What should I do when no marks are found?
Check the light-marks option, adjust the threshold, and crop away unrelated graphics. A blank image returns no text. Very small or merged shapes may require a better screenshot.
Are my pictures stored?
The tool uses your browser's image and canvas APIs and a local worker. It does not upload your image or save it to a site account. Clear the image or leave the page to discard it. Ordinary site analytics are described on the About page.
Can I decode typed dots and dashes instead?
Yes. Use the Morse code translator when you already have editable text; no image recognition is needed.
