Developer Toolbox
60 fast, offline tools to encode, hash, format, and convert data. Chain them into workflows and save the result as a paste. Everything runs in your browser.
Base64 Encode
Encode UTF-8 text to Base64.
Workflow (0 steps)
Chain tools into a pipeline. Add a tool with Add to workflow, then run them in order (each tool's output feeds the next). Example: Base64 Decode, then JWT Decode, then JSON Pretty Print.
Every tool on this page is free and runs entirely in your browser. Pastepile Pro is what funds them: encrypted drop boxes, dead-man's switches, threshold pastes, 25 MB API pastes, and permanent AI memory for MCP, at $8/month. See what Pro adds
