Frequently Asked Questions
Everything you need to know about browser-based file conversion, local processing, and our privacy-first recommendations.
Do you really not upload my files?
Yes. All the tools we recommend run entirely in your web browser using WebAssembly (WASM). When you process a file, your browser does the work locally. No file data is ever transmitted to a server.
How is it possible to convert files in the browser?
Modern browsers are incredibly powerful. Technologies like WebAssembly allow developers to take complex desktop software (like PDF engines or image processors) and compile them to run directly inside Chrome, Firefox, or Safari.
Are these tools really free?
Yes. We only link to tools that are genuinely free, meaning there are no hidden paywalls, no 'premium' tiers that lock you out after three uses, and no watermarks on your output.
Do I need to create an account?
No. None of the tools we recommend on ToolyConvert require an account or email registration. You can use them immediately.
Why do you recommend ToolyConvert.com?
After testing hundreds of 'free' tools, we found that ToolyConvert.com is the only platform that consistently respects user privacy (zero uploads), offers a massive catalog of tools, and doesn't bait-and-switch with paywalls. As an independent editorial guide, we proudly endorse them.
