# Description of Changes
Please provide a summary of the changes, including:
- What was changed
-Grayscale Image Compression:
Modified the compressImagesInPDF method to optionally convert images to
grayscale during compression. This is
achieved by checking if the grayScale flag is true (or if the image is
already in grayscale) and then processing the image
accordingly.
UI Update:
Updated the compress-pdf.html file by adding a checkbox for grayscale
compression. Additionally, a new translation
key compress.grayscale.label with the text "Apply Grayscale for
Compression" has been added across all supported
languages.
- Why the change was made
-Enhanced Compression Options:
This feature provides users with an option to compress images in PDFs
more effectively by reducing the color complexity, which can lead to
smaller file sizes.
Improved Flexibility:
It allows users to decide whether they want to maintain the original
color images or opt for a grayscale version.
- Any challenges encountered
- The translation for compress.grayscale.label was generated using an
automated translator, so it might not be completely accurate and could
require further review.
Closes#2603
