carbon.now.sh

Carbon (carbon.now.sh) is a tool for turning source code into shareable images, and its own page points you to about, source, terms, and privacy links for the details that govern use. In practice, that means the images themselves are yours to share, but you should read the terms and privacy pages before relying on Carbon for anything sensitive, and you should treat every exported image as public the moment you post it. Carbon is not a code host or version-control service, so it offers no repository privacy, access control, or history.

What Carbon actually does

Carbon's stated purpose is narrow: "Create and share beautiful images of your source code." The page describes the workflow directly — start typing or drop a file into the text area to get started. From there you adjust presentation with Theme, Language, Background, and Settings menus, then use Copy, Tweet, Share, or Quick export / Export to get the result out.

That scope matters for the terms question. Because Carbon renders an image rather than storing a project, there is no account-level code storage to reason about. What you paste in is what gets rendered, and what you export is a static image file.

Can you use the images freely?

The page itself does not state a license for exported images in the material available, so the safe reading is:

• The image is a rendering of code you supplied. If you wrote the code, you already hold whatever rights you have in it.
• If the code is not yours, the image does not change that. Pasting third-party or employer-owned code into Carbon and exporting it does not grant you a license to redistribute it.
• Check the terms page for any conditions Carbon places on use of the tool or its output. The site exposes a terms link precisely so users can review this rather than assume.

So "freely" is conditional: freely for code you have the right to share, subject to whatever the terms page says, and not a workaround for code you do not have rights to.

Privacy: the part that actually bites

The privacy consideration is less about Carbon's data handling and more about what you put into the text area.

Carbon renders exactly what you paste. There is no automatic redaction, no secret scanning, and no warning before export. Common leaks in code screenshots include:

The privacy page is the place to check how Carbon handles what you submit. Independently of that, the practical rule is: assume anything you export can be read by anyone, because a shared image is trivially copied, re-posted, and OCR'd.

Before you export: a short checklist

1. Open the terms and privacy links on the Carbon page and read them — they are the authoritative source, not this summary.
2. Strip secrets, credentials, internal hostnames, and personal data from the snippet before pasting.
3. Confirm you have the right to share the code at all, especially if it is proprietary or under an employer's policy.
4. Render and export, then re-read the image itself at full size — truncation and line wrapping can hide or expose lines you did not intend.
5. If the snippet is still sensitive after editing, do not export it. Use a synthetic example instead.

What Carbon is not

Carbon does not host code, manage versions, or provide private sharing. It generates an image and gives you export and share actions. If you need access control, revision history, or a private link, Carbon is the wrong tool — and no setting inside it will give you those properties.

Bottom line

You can use Carbon images freely for code you have the right to share, but the tool's own page directs you to its terms and privacy pages for the governing conditions, and neither the tool nor its export flow protects sensitive content. Read those two pages, sanitize the snippet before pasting, and treat every exported image as public.

Use Carbon when you want a clean, styled, shareable image of a code snippet rather than a raw screen capture. It lets you type or drop in code, then adjust theme, language, background, and other visual settings before exporting an image. A plain screenshot is faster if you only need to show exactly what is on your screen, but Carbon is better when presentation matters.

What Carbon actually does

Carbon is a web tool for turning source code into a styled image. The site describes it as "the easiest way to create and share beautiful images of your source code." You can start by typing directly into the text area or by dropping a file into it.

The interface exposes controls for:

• Theme
• Language
• Background
• Menu and settings options
• Copy, tweet, share, and quick export actions

That means the output is not just a cropped screenshot. It is a composed image with deliberate visual settings.

Carbon vs. a plain screenshot

The trade-off is straightforward: Carbon adds a styling step, but that step is the reason the result looks more presentable.

When Carbon is the better choice

Choose Carbon if you need to:

• Share a code snippet on a social platform where appearance matters
• Put a code example into a slide or document without unrelated screen clutter
• Produce a consistent visual style across multiple code images
• Avoid exposing your full desktop, tabs, or file paths that a screenshot might capture

For example, if you want to post a short function on a social feed, a plain screenshot may include your editor sidebar, terminal, or notifications. Carbon lets you isolate the code and apply a background and theme instead.

When a plain screenshot is enough

A plain screenshot is often better when:

• You need to show the exact state of an application, including menus and panels
• You are filing a bug report and context matters more than appearance
• You need to capture something outside a code editor
• You want the fastest possible capture with no configuration

Carbon is focused on source code images, so it is not a general screen capture replacement.

Practical considerations

The site includes links for about, source, terms, privacy, and offsets, and notes it was created by @carbon_app. If you plan to publish images, check those pages for the current terms and privacy details rather than assuming how your input is handled.

Carbon also offers sign in/up, but the page evidence does not state whether signing in is required for basic use. Treat account features as optional unless the interface requires them for a specific action.

Bottom line

Use Carbon when the goal is a polished, shareable image of a code snippet and you are willing to spend a moment adjusting theme, language, and background. Use a plain screenshot when speed or exact screen context matters more than presentation.

Carbon (carbon.now.sh) turns source code into a shareable image. You can start by typing directly into the text area or dropping a file into it, then adjust the appearance with the Theme, Language, and Background menus, and finish with Export or Quick export. This works for anyone who wants a clean code screenshot for a post, slide, or message — no design tool required.

Getting started

1. Open carbon.now.sh.
2. Either start typing in the text area or drop a file into it. The page states: "Start typing or drop a file into the text area to get started."
3. The code you enter becomes the content of the image.

Adjusting the look

Carbon exposes several controls in its menus:

• Theme — changes the color scheme of the code.
• Language — sets syntax highlighting for the code you entered.
• Background — changes the backdrop behind the code window.
• Settings — additional appearance options.

Set Language to match your code so highlighting is accurate, and pick a Theme and Background that keep the code readable against the background.

Exporting and sharing

When the image looks right, use one of these:

• Export — full export options.
• Quick export — a faster export path.
• Copy — copy the result.
• Tweet — share to Twitter/X.
• Share — share the image.

Common snags

• If highlighting looks wrong, check the Language menu — it may not match the code you pasted.
• If the code is hard to read, change the Theme or Background rather than editing the code itself.
• Dropping a file only works if the file contains the code you want; otherwise type or paste it into the text area.

Carbon also offers Sign in/up, and links to about, source, terms, privacy, and offsets, created by @carbon_app.

Carbon is a free web tool that turns source code into polished, shareable images. You paste or drop code into the text area, adjust the theme, language, and background, then export the result as an image. It fits anyone who wants a code snippet to look presentable on social media, in slides, or in documentation — and it needs no installation, just a browser.

What Carbon does

The site's own description is direct: "Create and share beautiful images of your source code." The workflow is built around a single text area:

• Start typing code directly into the text area, or
• Drop a file into it to load existing code.

From there, Carbon renders the code inside a styled window that you can customize before exporting.

The customization options

The interface exposes a set of controls for how the final image looks:

There are also Copy, Tweet, and Share actions, plus a Quick export option, so you can move the image out of Carbon without a separate download step if you prefer.

Who it's for

Carbon is useful when raw code in a plain text block looks flat and you want something more visual:

• Social posts — sharing a snippet on Twitter/X or similar platforms where a styled image reads better than plain text.
• Presentations — dropping a clean code image into slides instead of fighting with monospace fonts.
• Documentation and tutorials — illustrating a specific block of code with consistent styling.

Because the tool runs in the browser and takes either typed input or a dropped file, it works for quick one-off snippets as well as repeated use.

Practical notes

• The site is created by @carbon_app, and the page links to about, source, terms, privacy, and offsets pages if you want more background.
• A Sign in/up option exists, but the core create-and-export flow is presented as the primary action on the landing page — you can start typing or dropping a file immediately.
• The page itself does not state pricing, so treat cost as unconfirmed rather than assuming it is free or paid.

If your goal is simply to make a code snippet look good enough to share, Carbon covers that in a few steps: enter the code, pick a theme and background, then export.
