FAQ
Frequently asked questions
Do I need an account to use FreNiMi Tools?
No. Every currently published tool works without an account, payment, or license key.
Is my data actually private?
Tools marked "Runs locally" process supported content inside your browser. The webpage still loads assets and may send limited first-party usage events, but selected files, filenames, document contents, passwords, and generated output are not included. See the Trust Center for the exact boundary and verification steps.
Is there a file size limit?
FreNiMi Tools doesn't enforce a hard limit, but since processing happens in your browser rather than on a server, very large files are limited by your device's available memory.
Does FreNiMi Tools work on mobile?
Yes, every tool is responsive and works in mobile browsers. Large files may run more smoothly on desktop given memory constraints.
Are any current tools locked behind a subscription?
No. The complete published toolbox, including Watermark PDF, is currently free. Any future paid product will be separate and clearly explained before purchase.
