Compress and Optimize PDF
Shrink one PDF by recompressing its images and dropping unused data.

- 1
Upload one PDF
Add one unlocked PDF, or paste a PDF URL. The limit is 100MB and 40 pages.

Choose compression
High quality changes images less. Balanced is the default. Smallest file reduces them further.
- 3
Grayscale, if you want it
Turn on grayscale to convert the images to gray as well as shrink them.

Download the PDF
The result is still one PDF. If the file was already compact, the original is returned.
