About MyTool0
Useful software should get out of the way.
MyTool0 is an independently maintained library of focused browser utilities for small, concrete tasks—without turning every action into an account, dashboard, or upload flow.
The idea
One real task per page.
Most utility visits begin with a specific intention: count this text, convert this file, inspect this data, or calculate this date. MyTool0 starts from that job instead of asking the user to learn a large application.
Each public page must provide a working tool, explain material assumptions, and connect to genuinely related tasks. The catalog grows only when a new page represents a distinct need—not merely another keyword variation.
How we build
Three constraints keep the product honest.
- 01
Browser-first processing
When the browser can complete the task reliably, text and files stay in the current tab instead of being sent to a server for processing.
- 02
Static before interactive
Instructions, limitations, privacy details, and related links remain readable even before the tool workspace loads.
- 03
Quality before URL count
A smaller set of useful, tested pages is more valuable than hundreds of thin or near-duplicate destinations.
Maintenance
Results should be inspectable.
Tool processors are covered by automated checks for normal inputs, invalid inputs, and relevant boundaries. Public pages also pass catalog, metadata, and internal-link checks before changes are accepted. Browser workflows are exercised separately for interactive behavior.
Tests reduce regressions, but they do not make every result universally correct. File encoders, text segmentation, calendar conventions, and browser APIs have assumptions that can matter at the edges. Those assumptions belong on the relevant tool page rather than behind a vague accuracy claim.
If a result, explanation, accessibility behavior, or compatibility claim is wrong, use thecontact page and include the tool name plus a reproducible example that does not contain confidential data. Corrections are treated as product work, not as a reason to hide limitations.
