Compress PDF

Optimizes the file's structure and recompresses its streams — honest, lossless gains, often 10–30% on text-heavy documents. Image-heavy scans need the desktop app's real compression (image downsampling, quality control), which routinely achieves far more.

This tool runs entirely in your browser — nothing you type or open here is ever uploaded. You can disconnect from the internet after the page loads and it still works.
