关于 免费在线压缩PDF
Reduce the size of PDF files by re-rendering each page as a compressed JPEG image and rebuilding the PDF. Three presets are available: High Quality (80%), Medium (65%), and Maximum Compression (45%). A custom mode lets you set exact JPEG quality (10–95%) and image resolution (72–300 DPI). Shows before and after file sizes with savings percentage. A processing log gives feedback as each page is compressed.
