PDF Compressor

Shrink a PDF's file size by re-rendering each page at a controlled resolution and re-encoding it as a compressed JPEG. Works entirely in your browser — nothing is uploaded. Best for scanned or image-heavy PDFs; text-only PDFs may not shrink much since they're already compact.

How it works: each PDF page is rendered to a canvas at the chosen resolution, re-encoded as a JPEG at the chosen quality, and reassembled into a new PDF. This is very effective for scanned documents and image-heavy files. For PDFs that are mostly vector text, this method converts text to images, which usually increases file size and loses text selectability — for those, a tool that strips/recompresses embedded images directly works better.
