Questions, answered
Short answers to the things people actually ask. Can't find yours? Open the tool and poke it — it can't break anything.
Do my images get uploaded anywhere?
Never. The conversion runs entirely in your browser using the canvas API; once the page has loaded it even works offline.
If you're the trust-but-verify type, open devtools and watch the network tab stay silent.
Is it free?
Yes — free, no account, no watermark, no daily quota. The whole tool ships as static files.
Which image formats can I feed it?
Anything your browser can decode: png, jpg, webp and gif (first frame). Drop it, paste it, or browse for it.
How do I get a sharper result?
Start from a high-contrast image with a tight crop. Push columns up to 160-200, nudge contrast +15, and try invert if your subject is dark-on-light.
For photographic detail, the braille charset is the sharp one.
What does braille mode actually do?
Each character becomes a 2×4 grid of dots from the Unicode braille block, dithered with Floyd–Steinberg — roughly eight times the spatial resolution of a classic ramp.
It needs a font with braille glyphs, which every modern OS has.
Can I keep the original colors?
Yes. Color mode original samples the source color per character, gray keeps neutral tones, and green is the classic phosphor look.
Color survives in the .png export; plain-text copies are characters only, by nature.
Can I use the output commercially?
The output is yours — posters, readmes, merch, client work, anything. We don't claim rights over your art.
Any size limits?
Sources are downsampled to at most 300 columns, so even huge photos convert in milliseconds. If a very dense braille render feels slow on an old machine, lower the column count.
Still curious? The tool answers most questions in about ten seconds.
