Compressing Files with ZipGood
Short answer: To compress files with ZipGood, drag them onto the app window or Dock icon, choose one of the 14 output formats, configure that format's options, and click compress. ZipGood remembers your options per format.
Choosing an output format
ZipGood can create archives in 14 output formats: 7z, ZIP, TAR, GZIP, BZIP2, XZ, LZIP, Brotli, Zstandard, LRZIP, WIM, AAR, DMG and ISO. Choose the format that matches what the recipient or the target system needs — ZIP for maximum compatibility, 7z for the smallest file, and disk images such as DMG or ISO when you need a mountable volume.
The per-format options panel
- Compression method slider — trade speed against file size
- Split volumes — divide the archive into numbered parts
- Solid archives — compress files together for a better ratio (7z)
- Header encryption — hide the file list as well as the contents (7z)
- Password — protect the archive with AES-256 encryption where supported
- DMG volume name and format
Automatic archive naming
When the output file already exists, ZipGood automatically appends a number instead of overwriting your data — producing "Archive 2.zip", "Archive 3.zip" and so on.
