About Pocket Tools
Small, focused browser tools
Operated by Oneul AI Lab.
Finish common tasks without installing an app
Pocket Tools brings together image resizing, text counting, date and percentage calculations, QR generation, JSON formatting, CIDR inspection, and time-zone conversion. Each page is focused on one task and can be opened directly.
Inputs are processed locally
Text, JSON, selected images, and calculation inputs are processed in the browser running the tool. We do not require an account to display results, and the tools do not store the content of your work on a separate application server.
Assumptions and limits stay visible
The tools explain details such as inclusive dates, fixed UTC offsets, percentage formulas, and CIDR exceptions. Results are intended for quick reference and should be checked against an authoritative source before an important filing or production change.
