Passos

Abra a ferramenta e clique em Launch editor; o editor carrega no seu navegador na primeira vez.
Escolha uma linguagem na lista para ter destaque de sintaxe que combina com o seu codigo.
Escolha um tema claro, escuro ou de alto contraste para a sua tela.
Digite ou cole seu codigo, ou clique em Open a file para carregar um arquivo do seu dispositivo.
Clique em Save / Download para gravar seu trabalho em um arquivo (ou baixa-lo).
Opcionalmente, nomeie o conteudo e clique em Save snippet para guarda-lo neste navegador para depois.

Linguagens e tipos de arquivo

Quatro linguagens no editor de codigo: JavaScript (.js), TypeScript (.ts), Python (.py) e HTML (.html). — Quatro linguagens com realce de sintaxe - cole ou abra seu arquivo.

O editor destaca 18 linguagens e escolhe uma extensao de arquivo adequada ao salvar. Algumas comuns:

Linguagem	Extensao de arquivo salva
JavaScript	.js
TypeScript	.ts
Python	.py
HTML	.html
CSS	.css
JSON	.json

Salvar e snippets

Em navegadores baseados no Chromium o botao Save grava direto em um arquivo que voce escolhe; no Firefox e no Safari ele baixa o arquivo. Os snippets nomeados ficam no armazenamento local deste navegador, entao continuam la quando voce volta no mesmo dispositivo e navegador - eles nao sincronizam entre dispositivos, e limpar os dados deste site no navegador os remove.

O que esta ferramenta nao faz

E um editor, nao um executor. Ele escreve, destaca e salva codigo, mas nao roda nem executa o seu codigo - rode isso no seu proprio ambiente. Nada do que voce digita e enviado; o editor funciona totalmente no seu dispositivo.

Why trust these tools

Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
