Compression makes a PDF file smaller by lowering the quality of images inside the file. This is useful for sharing or storing, but too much compression can make images blurry or bad for printing. Picking the right compression keeps the file small but still clear for your needs.
Each time you compress a PDF, the images inside lose a little more quality. If you compress a file that was already made smaller before, the pictures can get much worse and text might look less sharp. Always start with the original PDF to keep your document looking as good as possible.
| Compression Level | Image Quality | File Size | Best For |
|---|---|---|---|
| Low (High Quality) | Best (keeps images clear) | Small reduction | Printing, sharing where quality matters |
| Medium | Good (some loss) | Medium reduction | General use, balance of size and quality |
| High | Lowest (images may blur) | Biggest reduction | Email, web upload, not for print |
