What is PDF Compresion?
PDF compression reduces the file size of a PDF document by optimizing its components, such as images, fonts, and metadata, without significantly compromising quality. Compression is particularly useful for:
Sharing: Smaller files are easier to email or upload to websites with size restrictions (e.g., 50MB limits).
Storage: Saves disk space on devices or servers.
Performance: Reduces load times for viewing or processing. Compression primarily affects:
Images: Reducing resolution (DPI) or quality (e.g., JPEG compression).
Fonts: Removing or subsetting embedded fonts not needed for display.
Metadata: Eliminating unnecessary data like editing history or private application data.
Structural Data: Optimizing file structure for efficiency. The effectiveness of compression depends on the PDF’s content. Files with many images compress better than text-only PDFs.
