Reduce PDF Size
The document is right; the file size is wrong. Reduction strips what inflates PDFs — oversized images, redundant data, scanner bloat — while the document you see stays the document you made. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

Where the megabytes hide
PDF size lives almost entirely in images: scans at needless DPI, photos pasted at full camera resolution, graphics stored uncompressed. Reduction resamples that data to what the document actually displays — routinely a 5–10× shrink with no visible change.
Reduce freely or to a number
