ToolBox

Frequently Asked Questions

Are these tools really free?

Yes. Every tool on ToolBox is free to use, with no sign-up required.

Do you upload my files to a server?

No. All processing happens locally in your browser using JavaScript. Your files never leave your device.

Is there a file size limit?

Since everything runs in your browser, the practical limit depends on your device's memory rather than a server quota. Very large files (500MB+) may be slow on lower-powered devices.

Can I use these tools on my phone?

Yes, all tools work on modern mobile browsers.
