Frequently asked questions
Is FileConverterPro really free?+
Yes — every tool has a free tier with sensible limits (25 MB per file). Pro lifts the limits and removes ads.
Are my files safe?+
Most tools process files entirely inside your browser, so they never leave your device. Tools that do require server processing delete files automatically (1 hour for Free, 24 hours for Pro).
Do I need to sign up?+
No — you can use any tool without an account. You only need an account if you want to upgrade to Pro.
What file types are supported?+
PDFs, common image formats (JPG, PNG, WebP), JSON, CSV and more. See the tools page for the full list.
