About

Webtoolio is a collection of free tools that run entirely in your browser. Today that means text and developer utilities, a Base64 encoder, a JSON formatter, a JWT decoder, and more. The plan is much broader: image tools, converters, and whatever else turns out to be useful, all added over time.

Nothing you type, paste, or open is uploaded anywhere. Each tool processes your input locally, on your machine. You can verify this yourself by opening your browser’s network tab while you use a tool: no requests carry your data anywhere.

There are no accounts to create and no ads. The site is free to use, and it stays that way. It’s built as a set of static pages served from a CDN, so pages load fast wherever you are.

Webtoolio is a small, ongoing project, maintained by one person who goes by impossibru. It exists because everyday tasks like formatting JSON or resizing an image shouldn’t require handing your data to someone’s server. Every tool’s logic ships with automated tests, and a browser test suite checks each page in both themes and on mobile before a change goes live. Found a bug, or missing a tool you rely on?
