How to make a PDF smaller

Several ways to reduce PDF file size, from compression to removing pages.

Compress images

Most PDF size comes from embedded images. The Compress tool re-encodes images at a lower resolution and quality.

If your PDF has pages you don't need, use Delete PDF Pages first — fewer pages means a smaller file.

For an extremely large file, split it into parts and share only what's needed.

For screen reading, Web or Email quality is enough. For printing, use Print quality to preserve detail.
