Pasos

Abre la herramienta y haz clic en Launch editor; el editor se carga en tu navegador la primera vez.
Elige un lenguaje en la lista para tener resaltado de sintaxis acorde a tu codigo.
Elige un tema claro, oscuro o de alto contraste para tu pantalla.
Escribe o pega tu codigo, o haz clic en Open a file para cargar un archivo de tu dispositivo.
Haz clic en Save / Download para escribir tu trabajo en un archivo (o descargarlo).
Opcionalmente, nombra el contenido y haz clic en Save snippet para guardarlo en este navegador para mas tarde.

Lenguajes y tipos de archivo

Cuatro lenguajes en el editor de codigo: JavaScript (.js), TypeScript (.ts), Python (.py) y HTML (.html). — Cuatro lenguajes con resaltado de sintaxis - pega o abre tu archivo.

El editor resalta 18 lenguajes y elige una extension de archivo adecuada al guardar. Algunas comunes:

Lenguaje	Extension de archivo guardada
JavaScript	.js
TypeScript	.ts
Python	.py
HTML	.html
CSS	.css
JSON	.json

Guardar y snippets

En navegadores basados en Chromium el boton Save escribe directo en un archivo que elijas; en Firefox y Safari descarga el archivo. Los snippets con nombre se guardan en el almacenamiento local de este navegador, asi que siguen ahi cuando vuelves en el mismo dispositivo y navegador - no se sincronizan entre dispositivos, y borrar los datos de este sitio en el navegador los elimina.

Lo que esta herramienta no hace

Es un editor, no un ejecutor. Escribe, resalta y guarda codigo, pero no ejecuta tu codigo - ejecutalo en tu propio entorno. Nada de lo que escribes se sube; el editor funciona totalmente en tu 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.
