Frequently Asked Questions
Everything you need to know about our browser-based utility suite
How do these tools work without uploading my files to a server?
OpenToolFactory runs entirely on client-side web technologies, including HTML5 Canvas, the FileReader API, and WebAssembly. When you drop a file onto our website, it is processed directly by your computer's browser engine. Your files never travel across the internet or touch our servers, guaranteeing 100% data privacy.
Can I use the output files for commercial and business purposes?
Yes. All tools on OpenToolFactory are free for both personal and commercial use. You maintain 100% intellectual property ownership of all output images, documents, invoices, or converted assets created using our tools.
Are there any file size or usage limits?
Because processing occurs on your device, we don't impose arbitrary cloud quotas or daily conversion limits. You can process as many files as you need. Performance depends only on your local device hardware and browser capabilities.
Do the tools work offline?
Yes. Thanks to progressive web app caching and local script execution, once a tool page is loaded in your browser, you can continue compressing, converting, or editing files even without an active internet connection.
