Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

function chilkatExample() {

    var success = false;

    // This example demonstrates how to compress a string and save the result
    // directly to a Gzip (.gz) file.

    var gzip = new chilkat.Gzip();

    // The string to be compressed:
    var inputStr = "The quick brown fox jumps over the lazy dog.";

    // Compress the string using UTF-8 and write to a file:
    success = gzip.CompressStringToFile(inputStr,"utf-8","output.gz");
    if (success == false) {
        console.log(gzip.LastErrorText);
        return;
    }

    console.log("Compression successful.");
    console.log("Gzip file written to output.gz");
