About Utilook
Utilook is a collection of focused web tools for everyday data, document, image, development, security, and network tasks. It was created to make small jobs easier to complete without installing a separate app or creating an account.
What Utilook provides
The collection includes developer, text, image, PDF, calculator, converter, generator, security, and web-network tools. Each released page must complete a specific task and explain how to use and interpret it.
How tools are reviewed
A tool is checked for representative and invalid inputs, clear errors, mobile and keyboard use, Korean and English consistency, privacy behavior, SEO accuracy, and a reason to exist independently. Tool count is not a release goal by itself.
Browser-first processing
When browsers can safely perform the work, inputs and files remain in the current browser session. The relevant tool page identifies this behavior and notes format, browser, memory, or file-size limits.
When a server is needed
Public DNS, HTTP, or TLS checks require a network request from a server, while a few features contact a named external service directly or through a privacy-preserving lookup. Those pages explain what is sent, why it is required, and whether it is stored.
Accuracy and limitations
Results are tested and documented, but calculators can use general reference ranges, file conversion can change unsupported features or metadata, and network results can depend on time and location. Important decisions should be verified against the applicable standard or qualified professional guidance.
Privacy, contact, and improvement
Utilook avoids collecting tool inputs unless processing requires a documented request, and it does not build user accounts in the current service. Read the Privacy Policy for operational details, or use Contact to report an incorrect result, accessibility issue, or unclear explanation. Reports are reviewed as part of ongoing maintenance.
