Pro Tips
- Text-based files like JSON, CSV, and XML compress exceptionally well with gzip, often achieving 70-90% size reduction.
- Already-compressed formats like ZIP, PNG, and MP4 will not benefit much from additional gzip compression due to their inherent optimization.
- Use batch compression for multiple files to quickly create a single compressed archive, perfect for sharing project folders.
- Keep your original files backed up before compression if you plan to modify them later, as compression is destructive.
