What is this?
A tool that turns a code snippet into a PNG image with syntax highlighting, built for sharing on social media (LinkedIn, X), Slack, Discord, or a repository README — where pasting raw code loses all formatting. Direct market reference: carbon.now.sh and ray.so, neither with a Portuguese interface.
How it works
Syntax highlighting uses Prism.js — the same library already used by this catalog's Paste Share — to identify keywords, strings, comments and other elements in your code. Instead of generating HTML like Paste Share does, this tool draws each token directly onto a <canvas> element, pixel by pixel, and exports the result as a PNG. All processing happens in your browser — the pasted code is never sent to any server.
Frequently asked questions
No. All syntax highlighting and image generation happen locally, in your browser, using the <canvas> element. No data is sent to Nexinon or any third party.
The card width has a deliberate cap — without it, a single very long line (a minified JSON, a URL inside a comment) would produce a disproportionately wide image, the opposite of a share-ready image. Text is never cut, only wrapped into more than one visual line.
Not in this version — the tool only uses Nexinon's own color palette (the same one Paste Share uses), to keep a consistent visual identity instead of reproducing third-party themes.
It's optional and can be turned off at any time with the corresponding toggle, but it ships on by default: since the whole image typically circulates outside Nexinon (LinkedIn, Slack, a README), the discreet corner mark is what lets anyone who sees the image find out where it came from.
