Frequently asked questions
Is my code uploaded to a server?
Never. Every CodeKit tool runs entirely in your browser with JavaScript. Your code is processed on your device and never touches a network — it even works offline once the page is loaded.
Are these tools really free?
Yes — 100% free, no sign-up, no limits, no watermarks. We keep the site running with minimal, non-intrusive ads.
Is there a file or size limit?
No hard limit. Because processing happens on your machine, the only constraint is your device’s memory. Files of several megabytes work fine.
