Introducing Qorventa
Qorventa is live. Calculators, formatters, converters and generators, usable immediately with no account.
Available now
The first release covers two categories.
- 10 financial calculators — loans, compound and simple interest, VAT, discounts, percentages, salary, take-home pay, retirement planning and age
- 15 developer tools — JSON formatting, validation and comparison, UUID generation, Base64 and URL encoding, JWT decoding, regex testing, SQL, HTML, CSS, JavaScript and XML formatters, YAML validation, and Unix timestamp conversion
Text, SEO, security and image tools follow.
Nothing leaves your device
Every tool runs inside your browser. Values you enter, text you paste and image files you open are never sent to a server.
That design has practical consequences.
- You can use it with sensitive data. Paste a production JSON payload or a config file — it does not go anywhere.
- It is fast. There is no network round trip between typing and seeing the result.
- It works offline. Once a page has loaded, the tools keep working without a connection.
Image tools are no exception. Files are processed on your device with the Canvas API and are never uploaded or stored.
Available in three languages
English, Korean and Japanese, each with its own URLs. Switch at any time from the control in the header, and your choice persists across visits.
Pages that have not been translated yet display in English. We do not use machine translation — the original reads better than a poor rendering of it.
What comes next
We are filling in the remaining tools and completing translations, starting with the most used. New tools and any significant changes will be announced here.
