Pixels darker than this become raised dots.
How it works
Open a picture
Open any photo or logo. Its Braille-dot version appears at once.
Tune width and threshold
Set the width, then move the threshold until the subject stands out from the background.
Copy or download
Copy the dots into posts and bios, or save them as a text file.
How Braille pictures work
Each Braille character packs a 2 × 4 grid of dots, so one character carries eight picture cells — far denser than one-character-per-cell art. Darker-than-threshold cells raise their dot, and the dots merge into remarkably detailed little pictures.
Simple bold shapes, logos and faces convert best. Fine gradients vanish because each cell is only on or off, so prefer stark subjects over subtle shading.
Tuning the threshold
The threshold splits dark from light: lower values raise dots only in deep shadows, higher values fill in mid-tones too. Slide it while watching the preview until edges and features separate cleanly from the background.
Keep the width modest — 60 characters already encode 120 picture cells across. Very wide outputs wrap in chat boxes and break the image into fragments.
Dotted out on this device
Your picture is thresholded and packed into Braille patterns entirely within this page. The conversion involves no network call, so the image you transform never goes anywhere.
Nothing is kept, studied or stored. When the tab closes, the dots live on only where you placed them.
Questions
Is my picture uploaded or sent anywhere?
No. The Braille patterns are computed inside your browser. Your picture never leaves your device.
Why is my result all dots or all blank?
The threshold misses your picture's tones: lower it for dark images that fill in, raise it for pale images that stay blank, until the subject separates.
Can screen readers read the result?
They read the Braille characters as dot patterns, not as the picture. Describe the image in words alongside the art for blind readers.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
