Common Mistakes While Compressing PDFs

❌ Choosing “High” for text-critical PDFs

High compression can reduce quality for scanned/image-heavy pages. Use Low/Medium for important readability.

❌ Expecting huge savings on already-optimized PDFs

Some PDFs are already compressed. In that case, reduction may be small — that’s normal.

❌ Compressing when you actually need Split or Merge

If your PDF is large due to many pages, consider splitting or reorganizing instead of compressing only.

❌ Uploading password-protected PDFs

Locked PDFs may not be modifiable. Use your PDF Unlock tool first.
