Every tool on Tooleux is tested before release. The suite spans hashing, cryptography, encoding, compression, and format conversion — 241 tools in total. Live test results are on the verification page.
Frequently asked
Are my files uploaded anywhere?
No. Every tool runs entirely in your browser using JavaScript and Web APIs. Files, text, and keys never leave your device. You can verify this by opening your browser's Network tab and using any tool. After the page loads, nothing you type or drop is transmitted.
Do I need an account to use Tooleux?
No. There is no signup, login, or email required. All 241 tools are available immediately without registration.
Is there a file size limit?
There is no server-side limit because files are never uploaded. The practical limit is your device available memory. Most tools handle files up to several hundred megabytes without issue.
Can I use Tooleux offline?
Yes. Once a page has loaded, the tool works with your network disconnected. This is possible because every tool runs locally in your browser rather than on a server.
How is Tooleux different from other online tool sites?
Most online tool sites process your input on their servers, which means your files and data travel over the network. Tooleux computes everything locally in your browser, so nothing you work with leaves your device.
Is Tooleux free?
Yes. All 241 tools are free, with no usage limits, no premium tier, and no account requirement.
