Tips to Get the Best PDF Compression Results
If your PDF has many high-resolution images, choosing a higher compression percentage or lower resolution setting significantly reduces size.
For documents with mostly text, lower compression levels preserve sharpness while still achieving good size reduction.
Don’t compress more than necessary — too much compression may make images look blurry or text less crisp.
Always preview the compressed PDF to ensure readability and layout haven’t degraded.
