What can you do here?
Use 30 tools for tasks ranging from character counts, discounts and dates to JSON formatting, YAML conversion and image resizing. Korean and English interfaces help students, professionals and developers use the same workspace.
No account is required. Choose between two themes and detailed or compact tool lists. Favorites are remembered only in the browser you are using.
How we approach the work
The tool code processes your text and selected files in your browser rather than uploading them to a server. Where an input cannot be processed, the interface provides an error you can act on.
- Work first: inputs, results, copy and download actions stay easy to find.
- Explain the rules: formulas, supported inputs, examples and limitations appear below each tool.
- Describe real behavior: no promises of unsupported features or unverified performance.
Using the results
Each tool helps with a specific calculation or conversion. External rules such as tax rates, submission character limits and legal deadlines still need to be checked with the relevant authority. Tool guides describe differences in numeric precision, time zones and file formats.
For consequential decisions, compare results with source records and an independent method. Keep a separate copy of your original files.
