Privacy & Security
Your data is 100% safe and private. All processing happens entirely in your browser using client-side JavaScript. Your data:
- Never leaves your computer
- Is never uploaded to our servers
- Is never stored, logged, or tracked
- Remains completely private
Even if you upload a file, it's read locally in your browser and never transmitted anywhere.
Once a tool page is loaded, it can work offline for basic operations since all processing happens client-side. However, you'll need an internet connection to initially load the page and access external libraries.
Yes! Since all processing happens in your browser and nothing is sent to our servers, you can safely use our tools with sensitive data.
However, as with any web tool, ensure you're accessing the site through HTTPS and your computer is secure.
Features & Usage
We support a wide range of data formats:

Since all processing happens in your browser, the limit depends on your browser's memory and processing power rather than our servers.
Most modern browsers can handle files up to several megabytes without issues. Very large files (100MB+) may cause performance issues depending on your device.
Most tools have an "Upload" button. Click it and select your file from your computer. The file will be read locally in your browser and displayed in the input area.
You can also copy and paste content directly into the input editor.
You have multiple options to save your results:
- Download - Click the "Download" button to save as a file
- Copy - Click the "Copy" button to copy to your clipboard
- Select All - Manually select and copy the output text
