Frequently Asked Questions
Does JSON Tools upload my files to a server?
No. JSON Tools runs entirely in your browser using JavaScript and the Canvas API built into the browser itself — your files never leave your device or get sent to any Nabukit server.
Is it safe to use JSON Tools with confidential files?
Yes. Since processing happens entirely in your browser's memory and is never transmitted over the internet, there is no point where a confidential file could be intercepted, stored, or leaked by Nabukit — it simply never receives it.
Why is Nabukit's Zero-Server execution safer than traditional online tools?
Traditional tools require uploading your file to a remote server to process it, creating a copy outside your control. JSON Tools runs with your own browser's engine (JavaScript), so that copy never exists — no server can lose, expose, or retain your data, because it never receives it in the first place.
Is there a size limit for the JSON?
There's no artificial limit set by Nabukit. The real limit is your browser's available memory — a JSON file of several megabytes works fine; one of hundreds of MB might make the browser feel slow, just like with any text editor.
