Dev Utilities

Top10k's dev utilities are small, single-purpose web tools that handle the everyday encoding, formatting, and conversion tasks developers repeat all day. Every tool runs in your browser — nothing is uploaded, and there is no account to create.

Encode and decode strings with the Base64 Encoder, which turns text or binary data into a Base64 string for data URIs and API payloads. Clean up source with the JS Formatter (configurable indentation, ES2020+ syntax) or shrink it with the JS Minifier, which strips whitespace, comments, and long variable names. Database work has the SQL Minifier for collapsing queries onto a single line.

Timestamp debugging is covered too: the Epoch To Date converter reads Unix seconds or milliseconds into a readable date. For docs and tickets, CSV to Markdown Table takes raw CSV and returns a formatted Markdown table, and Text To Slug turns any string into a URL-safe slug.

These are quick, no-friction alternatives to a desktop toolbox: open a tab, paste your data, copy the result. For language-specific formatting and linting see Developer Tools, for string manipulation see Text Tools, and for hashing and encoding helpers see Security & Privacy.
