JPEG Options
This format supports compression and works at all color depths. The image compression is adjustable, but beware: Too high a compression could severely reduce image quality, since JPEG compression is lossy. Use JPEG to create TrueColorWeb graphics, or if you do not want your image to take up a lot of space. JPEG is a good format for photographs.
JPEG files usually have an extension .jpg, .JPG, or .jpeg. It is a very widely used format, because it compresses images very efficiently, while minimizing the loss of image quality. No other format comes close to achieving the same level of compression. It does not, however, support transparency.

When you save a file in JPEG format, the dialog box allows you to set the Quality level, which ranges from 1 to 100. Values above 95 are generally not useful, though, the default quality of 90 usually produces excellent results, but in many cases it is possible to set the quality substantially lower without noticeably degrading the image. You can test the effect of different quality settings, by clicking Show Preview in the dialog box. Clicking this causes each change in quality (or any other JPEG parameter) to be visualized in the image preview.

Progressive encoding
Displays the image progressively in a web browser. The image appears as a series of overlays, enabling viewers to see a low-resolution version of the image before it downloads completely.

Grayscale
The image is converted to grayscale.






GIF Options
GIF images are in 8 bit indexed color and support binary transparency (but not semi-transparency). Use GIF for transparent Web graphics. For most purposes, though, PNG can be used in place of GIF and is a better choice. You can test the effect of different quality settings, by clicking Show Preview in the dialog box. Clicking this causes each change GIF parameter to be visualized in the image preview.

Palette
Specifies a method for generating the color lookup table and the number of colors you want in the color lookup table. You can select the color reduction methods.

Dither Mode
Determines the method of application dithering. GIF is an indexed image contains 256 colors or less, some colors in the original image may be absent in the GIF palette. This may result in some blotchy or solid colors in subtle color areas.

Make Transparent
When the Transparency option is selected, you can choose a transparency color. Use the Pipette to pick up a color from one part of the image and select the transparent color. Press this button and click on the original image to determine the transparent part. You can also double clicking the color box for open the color selector.

Matte Color
This is the color background of your web page. You can paste the html color code into your web page editor.



PNG Option
The format that is supposed to replace the GIF format. Truecolor images are supported, plus an alpha channel. PNG also uses compression, but unlike JPEG it does not lose image information. Use this format to save the images with a transparent background or with a transparency part.
