Can I compress a PDF to exactly 150 KB?

Our tool re-encodes images at reduced quality to shrink the file. The result depends on your PDF's content — image-heavy PDFs compress significantly, while text-only PDFs may not reach 150 KB because text data is already minimal.

Does compression reduce text quality?

Text remains sharp because the tool re-renders pages at a readable resolution. Only embedded images are re-compressed, which may lose some fine detail.

What if my PDF is already smaller than the target?

If your PDF is already under 150 KB, compression may not reduce it further. The tool shows before and after sizes so you can compare.
