Can I compress a PDF to exactly 4 MB?

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 4 MB 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 4 MB, compression may not reduce it further. The tool shows before and after sizes so you can compare.
