• Switch between minimum size, balanced quality, print, and prepress output.
• Get a smaller PDF instantly without installing desktop software.

How to choose the right compression level

If file size is your top priority — for example, sending by email or chat — choose Minimum size. For everyday sharing, Medium quality is recommended. For office printing, choose High quality. If you need to preserve the most colors and typographic details, select Prepress.

If the compressed file is still large, try Medium first, then decide whether to continue compressing to the smallest size. This usually gives the best balance between readability and file size.
