Compress PDFto the size you need

The photographs, and nothing else

Nearly all of a large PDF is usually a handful of photographs, so that is what gets compressed. Docqify finds the images inside the document, redraws them smaller using your browser’s own graphics engine, and writes them back — leaving the text, fonts and vector drawings completely untouched. That is why a compressed file still has selectable text and crisp lines at any zoom, and why a document made only of text barely shrinks at all: there was never anything heavy in it to remove.

• Give it a size to hit — 10 MB for an email, 200 KB for a strict upload form — and quality is lowered only as far as it takes to get there, never further.
• A file that already meets your target is returned exactly as it was, rather than re-encoded for no reason.
• Photographs stored as JPEG are re-encoded. Logos and line art stored in other formats are left alone, because re-encoding those costs quality and saves almost nothing. The tool tells you which it did.
• Everything runs on your device. The page ships a Content Security Policy that blocks connections to any other origin, so a document you compress here cannot be sent anywhere.
