About Utilerio

What this is

Utilerio started from a simple annoyance: the utilities you need mid-task — a ZPL preview, a JSON formatter, a margin calculation — are scattered across sites that bury the tool under three screens of copy, or ask you to sign up before you can paste anything.

Every page here does the opposite. The tool is the first thing on the page. The explanation, examples and FAQ come after it, for the people who want them.

How it is funded

The site is free and supported by advertising. Ads are placed above and below the tool, never between an input and the button that acts on it.

Paid plans (Starter, Pro, Advanced) add API access, batch processing and higher usage limits for developers who want to script against the tools. Every tool itself stays free to use in the browser.

What happens to your data

Most tools run entirely inside your browser tab. Nothing is uploaded, so there is nothing for us to store, log or leak.

The ZPL tools are the exception. Rendering a Zebra label requires a rendering engine, so the ZPL source is sent to our server, rendered in memory and returned to you. It is not written to disk, not attached to your session and not kept after the response. The Privacy Policy spells this out in detail.

Getting in touch

Bug reports, missing symbologies, wrong calculations and tool requests are all welcome. The contact form goes straight to the people who maintain the site.
