Understanding the Compression Options
- Basic Compression: Rebuilds the PDF structure to remove redundant data. This is a lossless process, best for text-heavy documents.
- Recommended Compression: Performs basic compression and also re-compresses images within the PDF to a medium quality. This offers a great balance between file size and visual quality.
- Strong Compression: More aggressively re-compresses images to a lower quality, resulting in the smallest possible file size. Ideal for when size is more important than image fidelity.
Our tool is most effective on unoptimized PDFs, especially those containing large, high-quality images (like PNGs or high-res JPEGs).
