Below is a complete guide on what PDF compression means, how it works, when you need it, and how to get the best results.

What Does It Mean to Compress PDF?
Compressing a PDF means reducing its file size without changing the actual content. This can be done by optimizing images, removing unnecessary data, and restructuring the file. The goal is to make the PDF lighter, faster to load, and easier to share.
There are two main types of PDF compression:
1. Lossless Compression
This method reduces file size without affecting quality. Everything stays the same, and the PDF can be restored to its original state if needed.
2. Lossy Compression
Lossy compression reduces file size more aggressively, usually by lowering image quality or removing hidden data. The final PDF still looks great but is much smaller.
iLovePDFApp gives you the perfect balance of quality and file reduction, letting you pick the level of compression that fits your needs.

2. Use the Right Compression Level
Choosing maximum compression isn’t always necessary. Pick a balanced option when quality matters.
3. Remove Extra Elements
Before compression, delete pages, watermarks, or graphics you don’t need.
