Compressed locally — nothing is uploadedAbout this PDF Compressor
Each page is re-rendered and re-encoded as an optimized JPEG, then reassembled into a new PDF — the same approach "print to PDF at lower quality" uses, but automatic. Savings are dramatic on scanned and image-heavy documents. Note that text becomes part of the page image, so the output is no longer text-selectable; keep the original for editing and use the compressed copy for sharing.
