Compress PDF in your browser
Reduce PDF file size without uploading the document anywhere. Everything runs on your device.
🔒 Files are processed in your browser and never uploaded.
Pick Optimize to rebuild the file and strip metadata while keeping text and links, or Strong (rasterize) to flatten image-heavy scans for the smallest size. Large, scanned PDFs shrink the most.
FAQ
Does this upload my PDF?
No. Compression runs entirely in your browser with vendored libraries; the file is never sent to a server.
Which method should I choose?
Use Optimize to keep selectable text and links. Use Strong (rasterize) for scanned or image-heavy PDFs when you need the smallest file and don't need to select text.
