About this tool
IconVault's Compression Streams tool compresses your text with the browser's native CompressionStream API: gzip, deflate and deflate-raw. See the original vs compressed size, the exact compression ratio, a byte-level hex dump, and the output as Base64, ready to copy.
Every run ends with an automatic round-trip check: the tool decompresses the output and compares every byte to the input, so you know the data survived. Download the compressed bytes as a file too. Free and runs fully in your browser.
