JPEG

The 'Quality' property controls the trade-off between image quality and file size when saving images with JPEG compression. Higher values preserve more detail but result in larger files, while lower values increase compression at the cost of visible artifacts.

• Set to a value between 0.01 and 1.0 (representing 1% to 100% quality).
• Typical values range from 0.6 (60%) for moderate compression to 0.9 (90%) for high quality.

Example:
0.75 (75% quality)

The 'Smoothing' property applies a smoothing filter to the image before compression, which can help reduce noise or minor artifacts. Excessive smoothing may blur fine details.

• Set to a value between 0.0 and 1.0 (representing 0% to 100% smoothing).
• Use low values for most images; increase only if noise reduction is needed.

Example:
0.1 (10% smoothing)

The 'Progressive' property determines whether the JPEG image is saved in progressive mode. Progressive JPEGs are displayed in multiple passes, allowing a low-quality version to appear quickly and gradually improve as more data is loaded.

• Enable for web or network scenarios where images are loaded over slow connections.
• Most modern viewers and browsers support progressive JPEGs.

Example:
true (save as progressive JPEG)

Can be one of the following values:

The 'DCT Mode' property selects the algorithm used for the Discrete Cosine Transform step in JPEG compression. Different modes offer trade-offs between speed and accuracy.

• 'Default': Uses the encoder's default mode (usually 'Slow').
• 'Slow': Slow but accurate integer algorithm.
• 'Fast': Faster, less accurate integer method.
• 'FloatingPoint': Floating-point method, may offer different performance or quality characteristics.

Example:
Slow
