GZIP compressor
Compress a file locally with fast, balanced or smallest GZIP settings and compare the resulting file size.
How it works & useful details
Compress one file with GZIP. Choose a balance of speed and file size.
Everything runs locally. Files are never uploaded. Maximum 16 MiB per input file, 32 MiB combined, and 1 file. Processing can be cancelled.
GZIP uses DEFLATE. Decompression verifies its header, size and CRC-32 and accepts single-member files only. Maximum expanded output is 32 MiB. A CRC check detects accidental corruption; it does not authenticate a file.
