⚫ High Compression applies to almost all images. If you intend for small-size images
and don’t care about the quality, High Compression can produce smaller images
than other compression methods do. (Available in Foxit PDF Editor Pro Only)
Tile Size: Divides the image being compressed into tiles of the specified size. (If the
image height or width is not an even multiple of the tile size, partial tiles are used on
the edges.) Image data for each tile is individually compressed and can be individually
decompressed. The default value of 256 is recommended. This option is available only
for JPEG 2000 format.
Quality: Available only for JPEG compression, JPEG 2000 compression, High
Compression, and JBIG2 compression. You can apply JPEG compression, JPEG 2000
compression, or High Compression to color and grayscale images at various levels
(Minimum, Low, Medium, High, Maximum). JPEG and JPEG 2000 compression methods
are typically lossy, which permanently remove some pixel data and may reduce image
quality. JPEG 2000 compression also offers lossless compression which means no pixel
data is removed. Compression for monochrome images is lossless, except for JBIG2
compression and High Compression.
Optimize images only if there is a reduction in size: With the option selected,
images will not be optimized if there are no reductions in file size from the image
setting.
 Unembed Fonts
Embedding all fonts allows anyone who opens your file to see the document as you
intended it to be seen. Without embedding fonts, the PDF viewer will substitute a font
with a close match or a default font which is available on the computer, and the display
results may be not exactly what you intended. If you don’t mind the difference and
prefer a smaller file, you can unembed fonts.
This panel contains two lists for fonts: fonts that are available for unembedding, and
fonts to unembed. To unembed fonts in a document, do as the following:
1. Select the checkbox for the panel first.
2. Select one or more fonts you want to unembed in the Embedded fonts list,
and click the Unembed>> button to add the fonts to the Fonts to unembed
list. If you want to only embed the characters (a subset of a font) used in the
document, select the Subset all embedded fonts option.
3. (Optional) To remove the added fonts from the Fonts to unembed list, select
the font and click the <<Retain button. If you don't want to unembed any font
in the document, select Do not unembed any font.
