Frequently asked questions
- Is Toolbox4Free really free?
- Yes. Every tool on Toolbox4Free is free to use, with no signup, no trial, and no paywall.
- Do my files get uploaded anywhere?
- Almost never. 285 of our 319 tools run 100% in your browser using JavaScript and WebAssembly — your files never touch our servers. The exceptions are the four Office conversions (PDF↔Word, PDF↔PowerPoint), the ten Network diagnostics (DNS, SSL, ports, HTTP headers, WHOIS, etc.), and the eight AI & Writing tools that call OpenAI on your behalf — all things that fundamentally need a server. Those tools clearly warn you with an amber notice on the page; nothing is stored.
- Do I need to create an account?
- No account is needed. Open the site, pick a tool, and use it immediately.
- Does Toolbox4Free work on mobile?
- Yes. The site is responsive and every tool works on modern phones, tablets, and desktops.
- Is there a file size limit?
- There is no fixed limit. Practical limits depend on your device's memory because everything is processed locally in your browser.
- Which browsers are supported?
- The latest two versions of Chrome, Edge, Firefox, and Safari are fully supported.
