How do I decode Morse code?

Paste Morse code into our decoder and it instantly converts dots and dashes to readable text.

What do dots and dashes mean in Morse code?

Dots (·) are short signals and dashes (−) are long signals, typically three times the length of a dot.

How do I separate letters in Morse code?

Use a space between letters and a slash (/) or larger space between words.

What Is Morse Code Decoding?

Morse code decoding is the process of converting a sequence of dots (short signals) and dashes (long signals) back into readable text. Originally developed by Samuel Morse and Alfred Vail in the 1830s, Morse code assigns a unique pattern of dots and dashes to each letter of the alphabet, every digit from 0-9, and common punctuation marks. Our decoder instantly reverses this process — paste any valid Morse code and see the English text appear in real time.

How Separators Work

Morse code uses timing and spacing to distinguish between symbols, letters, and words. In written Morse, a single space separates individual letters (e.g., .... .. = "HI"), while a forward slash or triple space separates words (e.g., .... .. / - .... . .-. . = "HI THERE"). Understanding these separators is the key to accurate decoding. Without proper spacing, Morse code becomes ambiguous — for example, ...---... could be "SOS" written without gaps or multiple separate characters.

Tips for Decoding by Ear

If you're trying to decode Morse code by ear, start by learning the most common letters first: E (one dot), T (one dash), A (dot-dash), and N (dash-dot). Listen for the rhythm — dots are quick and dashes are three times longer. The gap between letters is three times the length of a dot, and the gap between words is seven times. Practice with our interactive learning tool to build your recognition speed. You can also use our decision tree to trace dots and dashes to their corresponding letters, or study the complete alphabet chart. Ready to translate in both directions?
