Read Morse code straight from a picture.
A free image Morse code translator: drop a photo or screenshot of dots and dashes and it decodes the message on the spot. Also translates audio and text — all in your browser, nothing uploaded.
How the image Morse code translator works
- STEP 01 Drop a picture
A photo, scan or screenshot of Morse code. It is read on your device — nothing is uploaded.
- STEP 02 See what it detects
The marks are thresholded and measured, and shown back to you in a side-by-side preview so nothing is a black box.
- STEP 03 Read & fine-tune
Get the text instantly. If a mark is off, nudge the threshold, flip invert, or edit the detected Morse by hand.
No upload, no OCR black box. The picture is analysed with plain canvas pixel maths on your own CPU — grayscale, threshold, then measure each mark. You can watch exactly what it detected, and it keeps working offline once the page has loaded.

Used by the people who actually read dots and dashes
-
“Half my puzzles hide a message in a photo of dots and dashes. I paste the screenshot in, nudge the threshold once, and it reads the whole thing back — saved me from hand-decoding every prop I build.”
Elena Vasquez Escape-room designerReddit -
“I photographed a straight-key card at a hamfest and the picture decoder pulled the callsign out cleanly. The adjustable dot/dash split is what makes it work on real photos, not just perfect clip-art.”
Marcus Feld Ham radio operator (KD9xxx)X -
“My class sends each other Morse notes as images. Being able to drop a picture in and see it translate — right in the browser, nothing uploaded — makes it safe to use on the school Chromebooks.”
Priya Anand Middle-school STEM teacher -
“Cache logs love hiding coordinates in Morse. I snap the sign, load the photo, and the confidence score tells me when I need to re-shoot it straighter. Way faster than counting dashes by eye.”
Tom Bright GeocacherX -
“The audio decoder handles the beeping clips I record for my games, and the text side plays them back at the exact WPM I want. One tool for making the clue and for checking it — no install.”

Frequently asked questions
What is an image Morse code translator?
It is a tool that reads Morse code out of a picture. You upload a photo or screenshot of dots and dashes and it analyses the image pixel by pixel — thresholding the marks, measuring their width, and reading the gaps — to rebuild the Morse and translate it to text. Everything runs in your browser.
How do I translate a picture of Morse code?
Drop a picture onto the tool above (or click to choose, or paste a screenshot). It decodes the dots and dashes automatically and shows the translated text. If a mark is misread, adjust the threshold or invert switch, or edit the detected Morse directly.
Does it use OCR or AI?
No. It uses plain canvas pixel analysis — grayscale, an automatic brightness threshold, and width measurement of each mark. That is more reliable for dots and dashes than a general-purpose OCR or AI model, which are built for letters, not Morse.
Can it also do audio and text?
Yes. Switch tabs to decode a Morse audio clip into text, or to translate plain text to Morse and back — with tone playback, a flashing signal lamp and adjustable speed.
Is my picture uploaded anywhere?
Never. The image is read locally with JavaScript and the canvas API. There is no upload endpoint — you can open your browser network tab to confirm nothing is sent, and it even works offline after the page loads.
