About UtilBento
UtilBento is a small collection of free online utility tools built for everyday web work. The goal is simple: make common conversions, formatting tasks, date checks, and icon chores fast without requiring an account.
What UtilBento offers
The site includes browser-based tools for timestamps, JSON formatting, CSV to JSON conversion, Markdown tables, date differences, age calculation, salary estimates, compound interest estimates, favicon generation, and image to ICO conversion.
Local-first utilities
Many tools run directly in your browser. For tasks like formatting JSON, converting CSV snippets, or generating Markdown tables, the data you paste is processed on the page rather than sent to an application server.
Editorial approach
UtilBento guide pages are written to explain practical use cases, common mistakes, and safe ways to use simple web utilities. The site is maintained as an independent utility project for quick, low-friction tasks.
