Welcome to ZTools Documentation
ZTools is a free collection of 570+ developer & creator tools — JSON formatters, password generators, image compressors, regex testers, QR generators, PDF tools, and more. The vast majority run entirely in your browser: no signup, no upload, no data leaves your device. (A small paid Growth Suite adds AI-assisted SEO tools that need a sign-in and your own API key.)
This site documents how each tool works — with real use cases, worked examples, FAQs, and tips you won't find on the app pages alone.
What you can do here
- Browse all tools — see the full catalog organized by category.
- Read in-depth guides — task-oriented how-to guides covering common workflows.
- Reference release notes — the blog tracks new tools, improvements, and the dev journal.
- Open the app — every documented tool links directly to ztools.zaions.com.
Why ZTools exists
Most "free online tools" upload your data to a server, run paid analytics on you, or hide the actual product behind ads. ZTools is the opposite: open-source documentation, browser-only processing, no tracking that you can't disable, no upsell, no email gate.
The full source code for the documentation site you're reading is on GitHub — fork it, audit it, contribute fixes.
How content is organized
| Section | What's there |
|---|---|
| All tools | Every documented tool, grouped by category |
| Guides | Long-form how-to guides spanning multiple tools |
| Blog | Release notes, deep-dives, and the dev journal |
| Changelog | Version history |
Privacy & honesty
ZTools tools are browser-only by design. The privacy policy details exactly what happens with your input data (almost always: nothing — it stays on your device).
When a tool has limits, this documentation says so explicitly. We don't claim "all-in-one solution" when a tool only handles 80% of cases. Honest framing earns more trust than marketing copy.
