How to Compress a PDF Without Losing Quality

┌┐PDF files often balloon in size due to high-resolution embedded images, redundant font definitions, and uncompressed data streams. ### Why are PDFs so large? 1. **Uncompressed raster imagery**: A single 300 DPI scan can easily consume 20MB. 2. **Duplicated fonts**: Embedded font dictionaries across multiple merged documents add significant overhead. 3. **Form dictionaries and metadata**: Unnecessary revision logs and XML metadata. ### How PIXDF optimizes documents PIXDF applies loss-free Flate stream compression, optimizes object hierarchies, and downsamples excessive DPI imagery to clean web-standard resolutions while keeping text razor-sharp.
