The term "PDF compression" refers to the software-based reduction of a PDF file’s size without significantly compromising its content or visual quality. The primary goals of PDF compression are to save storage space, speed up file transfers (e.g., via email or web uploads), and improve performance when displaying the document on various devices.
Image Compression: Reducing image resolution or converting image formats within the PDF to minimize storage requirements.
Removal of Invisible Content: Deleting embedded but non-visible elements such as metadata, comments, or form fields.
Text Optimization: Using more efficient font encoding and removing redundant fonts.
Vector Graphic Optimization: Simplifying complex vector graphics or converting them into compressed raster images.
Merging Redundant Objects: Identifying and consolidating repeatedly embedded elements (e.g., logos or icons).
Compression Level Options: Allowing the user to choose between high compression (lower quality) and low compression (higher quality).
Batch Compression: Processing multiple PDF files in one operation to save time.
Preview Function: Comparing file quality before and after compression to verify results.
