Why ToolMars
Built differently from other tool sites
Your data never leaves your browser
Files and text are processed locally. Nothing is uploaded — ever.
No account, no paywall
Every tool is free forever. No caps, no premium tiers.
Built for real workflows
Redirect maps, schema markup, robots.txt — tasks you actually hit.
Batch when you need it
Convert, resize, or compress many files at once and grab a ZIP.
Privacy
Your files stay on your device.
Nothing gets uploaded
Image conversion, JSON formatting, Word to PDF — all inside your tab. No server receives your data.
Works with sensitive files
Safe for client docs, API keys, and anything you would not paste into a random site.
No account means no data trail
We never collect your email, usage history, or personal information.
