Tips for Maximum Compression

1. Compress images before creating the PDF — Use the Image Compressor first, then Image to PDF.

2. Use "Medium" for most purposes — Best balance between size and quality.

3. Split large PDFs first — Use PDF Split to isolate image-heavy sections.

4. Remove unnecessary pages — Fewer pages = smaller file.
