Frequently asked questions
Are these tools really free?
Yes — every tool on NoFrillzApps is completely free, with no signup, no watermark and no hidden limits.
Do my files or data get uploaded?
No. Every tool runs in your browser using JavaScript. Files, text and pasted data never leave your device.
Do the tools work offline?
Most do — once a page is loaded, formatters, converters and generators keep working without a connection. Only live-data tools like currency rates, IP lookup and SSL checks need the internet.
Are the tools safe?
Yes. The site is a set of static pages with no accounts, no tracking cookies and no third-party scripts beyond the ad network that funds the site.
