About Convertigo

Convertigo provides utilities for everyday tasks: converting CSV to SQL, validating JSON, calculating percentages and loan payments, converting units, and transforming text. Every tool on the site is functional. There are no placeholder features or simulated downloads.

Most tools run entirely in your browser using JavaScript. When you paste data into the JSON validator or select a PDF for merging, that content is processed on your device and is not uploaded to a server.

Some conversions — notably PDF-to-Word, Word-to-PDF, and PDF-to-Excel — cannot be done reliably in a browser. These are marked as unavailable rather than implemented in a way that would produce corrupt or misleading files. Their pages explain why.

Convertigo is deployed as a browser-only Next.js application. It does not require sign-in, and it does not store user files.
