Free Online Morse Code Decoder — Paste Dots & Dashes, Get Text Instantly

This Morse code decoder processes dots (.) and dashes (-) that you type or paste into the input field. Each letter in Morse code is made up of a combination of these short and long signals. For example, the letter A is dot-dash (.-), B is dash-dot-dot-dot (-...), and the distress signal SOS is three dots, three dashes, three dots (... --- ...).

The decoder recognizes standard International Morse code characters including all 26 letters of the alphabet, numbers 0 through 9, and common punctuation marks. Simply separate each Morse letter with a single space, and use a forward slash (/) to separate words. The decoder instantly maps each Morse sequence to its corresponding character.

This Morse code decoder is entirely browser-based — your data never leaves your device. There is no server processing, no upload, and no storage of your input. You can decode sensitive messages with complete privacy.

This Morse code decoder is purpose-built for typed input — use it when you already have a Morse code sequence as text and need to read what it says. Common scenarios include decoding puzzle clues from escape rooms and geocaching, checking answers from Morse code practice worksheets, or verifying a manually typed Morse sequence before transmitting it.

If your Morse code is in an audio recording rather than typed form, use our audio Morse code translator instead, which can decode sound files directly. If you have a live audio source like a radio transceiver or a practice oscillator, our live Morse code decoder listens through your microphone in real time.

For visual Morse code in images or screenshots, switch to the image Morse code translator which includes zoom and contrast tools. If you want to encode English text into Morse code instead of decoding, head over to English to Morse code.

Getting accurate results from a Morse code decoder depends on correct input formatting. Always use a single space between letters and a slash (/) between words. For instance, "HELLO WORLD" should be formatted as .... . .-.. .-.. --- / .-- --- .-. .-.. -... Missing or extra spaces can cause the decoder to merge or split characters incorrectly.

If your decoded text looks wrong, check for these common issues: missing spaces between letters causing characters to run together, incorrect dot/dash patterns from transcription errors, or non-standard characters that the decoder doesn't recognize. Use our Morse code chart to verify individual character patterns.

For beginners learning to recognize Morse code patterns, we recommend practicing with the learn Morse code by sound guide, which teaches pattern recognition without relying on visual lookup tables. Decoding by ear is significantly faster than decoding by eye once you build the skill.
