Why Compress PDF Files?
PDF files can become quite large, especially when they contain high-resolution images, embedded fonts, or complex graphics. Large PDFs are difficult to share via email, slow to download, and consume unnecessary storage space. Compression can reduce file sizes by 50-90% while maintaining readability.
Types of PDF Compression
1. Lossless Compression
Lossless compression reduces file size without losing any data or quality. This is ideal for text documents and simple graphics.
2. Lossy Compression
Lossy compression reduces file size by removing some data, typically affecting image quality. This is suitable for PDFs with many images where slight quality loss is acceptable.
PDF Compression Techniques
1. Image Compression
Images within PDFs are often the largest contributors to file size. Compressing these images can dramatically reduce the overall PDF size.
2. Font Optimization
Embedded fonts can increase PDF size. Consider using standard fonts or subsetting fonts to include only the characters you need.
3. Remove Unnecessary Elements
Remove metadata, comments, and unused objects from your PDFs to reduce file size.
