*
Picture measurement
The dimensions of the picture additionally impacts the compression ratio. Smaller photos compress extra effectively than bigger photos.
*
Picture complexity
The complexity of the picture additionally impacts the compression ratio. Photos with numerous element compress much less effectively than photos with easy options.

| Compression Ratio | File Measurement | Picture High quality |
|---|---|---|
| 50% | Half the scale of the unique file | Good |
| 75% | 1/4 the scale of the unique file | Honest |
| 90% | 1/tenth the scale of the unique file | Poor |
The optimum compression ratio for a selected picture is dependent upon the supposed use. For photos that will likely be seen on the net, a compression ratio of 80-90% is often ample. For photos that will likely be printed, a compression ratio of 95-100% is advisable.
Sustaining Picture Metadata in JPEG Recordsdata

Some in style EXIF viewers embrace:
| EXIF Viewer | Options |
|---|---|
| ExifTool | Free and open-source EXIF editor |
| JPEGsnoop | Cross-platform EXIF viewer and editor |
| IPTC Viewer | IPTC metadata viewer and editor |
Conclusion
JPEG is a flexible and extensively used file format for storing and sharing photos. Nevertheless, you will need to concentrate on the metadata that’s saved in JPEG information and the way to protect it throughout modifying and processing.
