- 2Choose a compression level: Low (minimal quality loss), Medium (balanced), or High (maximum compression).

How much can I reduce a PDF file size?
Most PDFs can be compressed by 40–70%. Image-heavy PDFs compress more than text-only documents.
Will text remain readable after compression?
Yes. Even at high compression levels, text remains sharp. Images may show slight quality reduction at maximum compression.
Does compressing a PDF affect printing quality?
Low and medium compression are safe for printing. High compression is recommended for digital sharing only.
Can I compress multiple PDFs at once?
Currently the tool processes one PDF at a time. Process each file separately.
