Compress PDF online — no upload
Shrink a PDF in your browser with a quality slider and a live size comparison. The file never leaves your device.
Original and compressed sizes will appear here after you choose a PDF.
How do I compress a PDF?
- Drop a PDF or choose it from your device.
- Set the quality slider. Lower values usually mean a smaller file.
- Wait for local compression, preview, then download.
Pages may be redrawn as JPEG so the file gets smaller. Keep the original if you need selectable text.
