Compatibility, privacy and limits
Input is processed in the browser. WebToolMint does not intentionally upload the file or text to its own server. A few tools load an open-source component from a CDN before processing.
This is a lightweight whitespace/comment reducer, not a full JavaScript parser. Back up and test important code; use a production minifier such as Terser for deployment.
Check the result after processing. For file tools, keep the original until the downloaded output has been verified.
