Frequently asked questions
Do I need an account to use Toolew?
No. Every tool works without signing up. An optional account lets you save projects, keep favorite tools and access your history on other devices.
Are my files uploaded to a server?
Most tools process data entirely in your browser using JavaScript and WebAssembly, so your text, images, PDFs and media never leave your device. The few tools that need the internet, such as DNS lookups or currency rates, say so clearly on the page.
How many tools does Toolew have?
Toolew currently offers 509 tools across 27 categories, from text and developer utilities to PDF, image, finance and health calculators. New tools are added regularly.
Can I use Toolew on my phone?
