Exporting images for the web

Corel PHOTO-PAINT lets you export the following web-compatible file formats: GIF, PNG, and JPEG.

While specifying exporting options, you can preview an image with up to four different configurations of settings. You can compare file formats, preset settings, download speeds, compression, file size, image quality, and color range. You can also examine previews by zooming and panning within the preview windows.


Component	Description
1. Preview window	Displays a preview of the document.
2. Preview modes	Lets you preview the adjustments in a single or split frame.
3. Zooming and panning tools	Lets you zoom in and out of an image displayed in the preview window, pan an image displayed at zoom level higher than 100%, and fit an image to the preview window.
4. Eyedropper tool and sampled color swatch	Lets you sample a color and display the sampled color.
5. Preset list box	Lets you choose preset settings for a file format.
6. Export settings	Lets you customize export settings, such as color, display options, and size.
7. Format information	Lets you view file-format information, which is available for each preview frame.
8. Color information	Displays the color values for a selected color.
9. Speed list box	Lets you choose an Internet speed for saving the file.

You can export web-compatible files using preset settings. This allows you to optimize the file, without the need to modify individual settings. You can also customize the settings to produce a specific result. For example, you can adjust its color, display quality, and file size.

Choosing a web-compatible file format

This table is a quick reference for choosing a web-compatible file format.


File format	Ideal for
GIF	Line drawings, text, images with few colors, or images with sharp edges, such as scanned black-and-white images or a logos. GIF offers several advanced graphic options, including transparent backgrounds, interlaced images, and animation. It also lets you create custom palettes for the image.
PNG	Various image types, including photos and line drawings. The PNG file format (unlike the GIF and JPEG formats) supports the alpha channel. This allows you to save transparent images with superior results.
JPEG	Photos and scanned images. JPEG files use file compression to store an approximation of an image, which results in some loss of image data, but does not compromise the quality of most photographs. You can choose the image quality when you save an image — the higher the image quality, the larger the file size.

Exporting palette-based images

Palette-based images, such as paletted GIF and 8-bit PNG, allow individual pixels to retain their exact color value. This lets you control the display of colors in the file when exporting. Palette-based images also allow you to introduce transparency to a file by choosing a color in the image and making it transparent. For information, see Creating palette-based images with transparent colors and backgrounds.
