What image formats can I upload?

Anything the browser can decode — PNG, JPG, JPEG, WebP, GIF, BMP, and SVG all work. Animated GIFs are converted from their first frame only; if you need every frame, split the GIF first (the ASCII would be a wall of text anyway). Max practical size is ~10 MB / 4000 px on a side; bigger than that and the browser may stall while decoding. The sampling canvas downscales internally to 400 px on the longest side, so beyond that resolution you get the same ASCII either way.

Why does my output look squished vertically?

A monospace cell is roughly twice as tall as it is wide, so a 50×50 pixel sample naively rendered as 50×50 chars would look stretched. The converter halves the row count automatically to compensate. If your particular font is closer to 1.5:1 (some condensed terminal fonts are), the result will look slightly stretched — set a CSS `line-height: 0.8` on the output ` ` to tighten it, or paste into a terminal whose font has a 2:1 aspect ratio.

When should I use 10 / 16 / 32 levels?

Use 10 for line art, logos, and pixel art where you want clear edges and a posterised look — the classic " .:-=+*#%@" Bourke ramp. Use 16 for general photos (faces, scenery) — the extra glyphs smooth out skin tones and skies. Use 32 for portraits and dark gradients where you want to keep midtone detail; the dense ramp packs more characters into the bottom half of the tonal range, which is where most photographic information lives.

What does the "invert" toggle do?

By default the converter assumes a dark terminal: dark image pixels become dense glyphs like `@` and `#`, bright pixels become sparse glyphs like `.` and space. If you're going to paste into a light-background context (a Markdown README that GitHub renders white, a printed page, a Word doc), flip "invert" so dark image pixels get sparse glyphs instead — the art will still be recognisable, just with the ink-dark mapping reversed.

Is the image uploaded anywhere?

No. The file is read into a `Blob`, drawn to an off-screen canvas via `URL.createObjectURL`, and the pixel buffer is read back with `getImageData` — all in the browser. There's no network request, no analytics ping with the filename, no temporary upload. You can verify in DevTools Network tab: no fetches fire when you drop a file. Useful for screenshots that contain anything sensitive.

Can I use my own characters — like emoji or my name?

Yes. Pick the "Custom" tab in the character-set row and type any string of length ≥ 2, ordered from light to dark. Examples that work: ` .:+*#@` (classic), ` ░▒▓█` (Unicode block elements, gives a smooth blocky look), `lilei` (turns your image into a mosaic of your name). Emoji also work but each one occupies one monospace cell on some terminals and two cells on others, so the aspect ratio may break — test in your target environment.

Drop an ASCII banner into a CLI tool's --help screen

Your Node CLI prints a plain text name on launch. Run your 200x200 logo through at width 60, pick the 16-level ramp, copy the output, and paste it as a template literal in the startup banner. At 60 columns it stays under 30 rows, so it fits an 80x24 terminal without scrolling and reads fine on a dark prompt.

Turn a profile photo into a GitHub README mosaic

You want a portrait at the top of your README that GitHub renders on a white page. Upload the headshot, set width to 100, switch on invert (GitHub is light-background), and choose the 32-level ramp to keep facial midtones. Wrap the result in a fenced code block so the monospace spacing survives, and the face stays recognisable at roughly 100x50 characters.

Spell a teammate's name into a leaving-card mosaic

For a farewell card, take a 250px photo of the person, pick the Custom charset tab, and type their name lowercase, light to dark, like " emma" with two leading spaces. Set width to 120. The image rebuilds itself entirely out of the five letters of their name, which prints cleanly on an A5 card at about 8pt monospace.

Make a retro 404 page out of your site mascot

Convert your mascot PNG at width 80 with the classic 10-level " .:-=+*#%@" ramp, download the .txt, and drop it inside a on your 404 route. At 80 columns the file is roughly 4 KB of plain text, adds zero image requests, and gives the error page a deliberate terminal-art feel that loads instantly even offline.

What this tool does

Convert any image to ASCII art directly in your browser. Drop a PNG, JPG, WebP, or GIF and watch it become a grid of characters you can paste into a README, a code comment, a Discord message, or a retro 404 page. Three built-in character ramps (10, 16, 32 tonal levels) cover everything from coarse line art to smooth photo gradients, and a custom-charset box lets you spell your own name or emoji sequence into the output. The width slider goes from 20 to 250 columns, the invert toggle flips the ramp for light terminals, and one click copies the whole thing or downloads it as a .txt file. Sampling is Rec. 709 luma on the canvas pixel buffer — semi-transparent pixels get pre-multiplied against white so logos with cutouts don't end up as dark blobs. 100% client-side: the image never leaves your tab.

Make a retro 404 page out of your site mascot
Convert your mascot PNG at width 80 with the classic 10-level " .:-=+*#%@" ramp, download the .txt, and drop it inside a <pre> on your 404 route. At 80 columns the file is roughly 4 KB of plain text, adds zero image requests, and gives the error page a deliberate terminal-art feel that loads instantly even offline.

Common pitfalls

Pasting output into a proportional font (a normal Markdown paragraph) breaks alignment. Always wrap it in a fenced code block or a <pre> so each glyph keeps a fixed cell width.
Leaving invert off when targeting a white page makes the art look like a photo negative. Toggle invert for light backgrounds (README, print) and leave it off for dark terminals.
Custom charsets ordered dark-to-light invert the whole image. List characters light-to-dark, e.g. " .:+*#@" with the space first, or the bright sky comes out as solid @ signs.

Privacy

The image is decoded and sampled entirely in your browser via a canvas and getImageData; it is never uploaded, and no filename or pixel data is sent anywhere. The ASCII output and your width, ramp, and invert settings stay on the page and are not written into the URL, so sharing the link never leaks your picture. Close the tab and nothing persists.
