ToolDesk

合同会社HS (HS LLC)

ToolDesk exists to make handy everyday utilities usable from the browser alone — no sign-up, no installation. It brings together a wide range of tools in one place: JSON formatting, image compression and cropping, QR code generation and reading, character counting, password generation, bill splitting, scheduling, and more.

Each tool includes original content explaining how it works, when to use it, and common pitfalls, and we also publish guide articles. Rather than just listing tools, we aim to provide accurate, practical information so people can use them correctly and safely.

We continuously add tools, improve existing ones, and revise explanations. Please send corrections or requests to the contact address below.

The Site is designed to keep your data on your device as much as possible. Most tools process the text and images you enter, paste, or upload only within your browser and do not send them to a server. The one exception is the scheduling tool, which stores input on a server so it can be shared with others to collect answers. See the Privacy Policy for details.

The Site is available in Japanese and English and works on smartphones. All features are free, and no account is required.

For inquiries about the Site (requests, bug reports, corrections to content, and so on), please contact us by email at the address below. We will review and respond in turn.
