PDF Compressor

Best for large merged PDFs (especially scanned/image-heavy files).

1) Upload PDF

Tip: If the PDF is huge, try compressing a smaller page range first, then merge parts back using your PDF Merger tool.

2) Settings

Why size might not drop: If your PDF is mostly text/vectors, use Lossless optimize. For scanned images, use Recompress pages with a lower DPI/quality.
