Drop the PDF you want to shrink.
Choose a compression level, and whether to also drop details and flatten forms.
Compare the size before and after, and download the smaller PDF.
Resize pages to A4, Letter or a percentage, keeping the content.
Save PDF pages as PNG, JPG or WebP images, alone or in a ZIP.

No. Your browser rewrites the PDF on your device, which is also why compressing a large file takes a moment.
On Light it’s the same document, only rebuilt. On the other levels only the embedded photos are re-encoded in place, so text stays selectable; a photo that wouldn’t get lighter is left untouched. That’s why a text-only file barely changes size instead of growing.
Recommended for sending by email or uploading to a form. Strong or Maximum when the file has to fit a strict size limit and you can accept softer images.
