How to Use the ASCII Table Online

The full ASCII table with decimal, hex, octal, binary and HTML codes. The first 32 are control characters rather than printable ones — including tab, newline and carriage return, which is why a text file can contain bytes that display as nothing.

No software to install Free Works on any device

Step-by-Step Guide to Using the ASCII Table

1

1. The whole table is on the page already
2

2. Type a character, a name or a code into the search box to jump to a row
3

3. Every row shows the decimal, hex, octal, binary, HTML, CSS and JavaScript form

What is the ASCII Table?

Why Use Web Development Tools in the Browser?

Small web jobs like minifying CSS, checking HTML, escaping a string or writing a Dockerfile rarely deserve a new install. These tools do each one in a tab, and your code is never sent to a server.

“The fastest tool is the one already open in a tab.”

Code checked for errors
Messy code made readable
Number bases converted
Selectors and paths tested

Minified files for faster pages
Config files from templates
CI workflows drafted quickly
Source code stays private

Popular Uses for Developer Utilities

These are the small tasks that interrupt a day of web work.

Minifying assets Shrink CSS or JSON before deploying, then beautify it again to read.
Validating markup Catch unclosed tags and syntax errors in HTML, CSS or JavaScript before publishing.
Docker setups Draft a Dockerfile, Docker Compose file or .dockerignore for a new project.
CI pipelines Generate a GitHub Actions or GitLab CI workflow and adjust it to fit.
Number conversions Convert between binary, decimal, hex and octal while reading low-level data.
Selector testing Try a CSS selector or JSONPath expression against sample input and see matches.
Data URIs Turn a small image into a data URI to embed directly in CSS.
Project files Create .gitignore, EditorConfig and CODEOWNERS files without copying them from old repos.

What You Can Do with the ASCII Table

Converts in every direction at once instead of one pair at a time

Handles values past 32 bits without silently losing precision

Why Use ToolXkit for ASCII Table?

Your files stay with you

Everything runs inside your browser. Nothing you open or type is uploaded to a server.

Web Dev Tools for Different Users

Front-end developers

Validate, minify and beautify HTML, CSS and JavaScript as part of daily work.

DevOps engineers

Draft Docker, cron and CI files quickly, then refine them in the repo.

Coding students

Learn number systems, escapes and selectors by trying examples and seeing results.

Technical writers

Escape code samples and check snippets before putting them into documentation.

QA testers

Write clear bug reports and test CSS selectors against real page markup.

Open source maintainers

Set up issue templates, CODEOWNERS and gitattributes for a shared project on GitHub.

Best Times to Validate or Minify Code

Keep these open in a tab when you are:

Starting a new repository
Preparing a site for launch
Tracking down a syntax error
Containerising an app
Setting up automated builds
Reading hex or binary values
Writing a bug report
Working on a locked-down laptop

Frequently Asked Questions

Answers to common questions about this tool.

Do I need to install anything to use the ASCII Table?

No. ASCII Table runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.

Is it safe to use the ASCII Table online?

Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.

Is my code sent to a server when I use ASCII Table?

No. Your code is processed in the browser tab, so private repositories, keys in config files and client work stay on your machine. It also means the tool works on locked-down work laptops where installing software is not allowed.

Will minifying break my code?

Minifying removes spaces, comments and line breaks without changing what the code does. Keep an unminified copy for editing, and test the minified version before deploying it.

Are the generated config files ready to use?

They give you a sound starting point based on common settings. Every project is different, so read through the file and adjust paths, versions and secrets before committing it.

Is ASCII Table free with no account?

Yes. There is no login, API key or usage cap. Open the page whenever you need it, even on a machine that is not your own.

Does ASCII Table follow current web standards?

The validators and generators follow current web standards and common tool conventions. Standards keep moving, so for edge cases check MDN or the official specification listed in further reading.
