Frequently Asked Questions
Does compression affect text readability?
No. Vector text instructions remain mathematically defined and razor-sharp. Only embedded photo images are optimized.
What is the difference between the compression quality levels?
Balanced (recommended): optimizes images to ~50% quality — best for most documents. High Quality: keeps images at ~80% quality with moderate size reduction. Maximum Compression: aggressively compresses images to ~20% quality for the smallest possible file, ideal for archiving.
How much will my PDF be reduced in size?
Results depend on how many embedded images the PDF contains. PDFs with many photos or scanned pages can be reduced by 50-70%. Text-only PDFs with no embedded images may see minimal reduction since vector text is already compact.
Will compression affect my PDF's text searchability?
No. Only raster (photo) images inside the PDF are re-encoded. Vector text, fonts, and searchable text layers are untouched and remain perfectly readable and searchable.
