Data Compression Calculator: Estimate File Compression Savings
Want to know how much data and storage space you can save by compressing your files? Well, I have an excellent tool for you. Just enter the type of files, i.e., images, videos, documents, or mixed, and give us the size and the level of data compression you want to use. This tool will provide you with the estimated compressed size and the percentage of saved storage.

Recommendation
Based on your data type and size, we’ll recommend the best compression method after calculation.
Tips for Better Compression
- For text files: Remove unnecessary whitespace and comments before compression
- For images: Consider lossy compression if quality isn’t critical
- For mixed content: Archive similar file types together
- For backups: Split large backups into smaller chunks for better compression
Compression Method Comparison
| Method | Best For | Speed | Ratio |
|---|---|---|---|
| GZIP | General purpose, web content | Fast | Medium |
| ZSTD | Balanced speed/ratio | Very Fast | Good |
| LZMA | Maximum compression | Slow | Best |
| Brotli | Web content, text | Medium | Very Good |
| LZ4 | Speed critical | Fastest | Low |
Note: Results are estimates based on typical compression ratios. Actual savings depend on data content, patterns, and compression algorithm used.
The tool uses simple but effective calculations with detailed results to give you information about the right type of compression for your tasks.

Different File Types
Files with higher redundancy, like text or number files, can be compressed much more easily and quickly.
Different Compression Levels
The tool allows you to choose different compression levels to select. Now, in tools like WinRAR, you’ll see compression methods like fast, the fastest, slow, etc. This is where our levels will fit into those methods.
| Compression Level | Compression Ratio | Speed | Approximate Dictionary Size | Data Integrity |
|---|---|---|---|---|
| Low Compression | 5-15% reduction | Very fast | 4 KB – 32 KB | Lossless |
| Medium Compression | 20-30% reduction | Moderate speed | 64 KB – 512 KB | Lossless |
| High Compression | 40-50% reduction | Slower | 1 MB – 8 MB | Lossless |
| Lossless Compression | 30-60% reduction (variable) | Variable speed | 16 MB – 64 MB | Lossless |
So, don’t get confused when you have to select the low, medium, high, or lossless options, The High compression will be slower and result in much more compression and storage savings.
