About
MultiKit is a small collection of developer utilities that run entirely in your browser. No accounts, no uploads, no tracking of what you paste in.
What MultiKit is
MultiKit gathers the everyday encoding and text tools developers reach for — starting with Base64 encode and decode — into one fast, clutter-free site. Each tool does one thing and loads instantly.
The toolset grows over time. Image resizing, cropping, and more text utilities are on the way, all following the same principle: do the work in the browser and nowhere else.
How it works
Every tool runs 100% client-side. When you encode a string or decode a file, the computation happens in your browser using native web APIs — the data you enter is never sent to a server, because there is no server to send it to.
MultiKit is a static site: just HTML, CSS, and a little JavaScript delivered from a CDN. That is what keeps it fast and what makes "nothing leaves your browser" a structural guarantee rather than a promise.
Who makes it
MultiKit is built and maintained as an independent project. If you have a tool you wish existed, a bug to report, or feedback of any kind, we would like to hear it — see the Contact page.
