Compress PDF Ruby Overview
The Compress PDF Ruby SDK by ConvertAPI is a tool that allows for the compression and reduction of PDF file sizes by up to 90%. This Ruby SDK optimizes PDF quality by compressing text, graphics, images, subsetting fonts, and optimizing document structure. It offers various parameters for customization, including compression presets, color and grayscale image compression, and options to remove elements like bookmarks, annotations, forms, and embedded files from the PDF. The Ruby SDK also provides options for optimizing the PDF for web viewing and preserving the PDF/A standard.
