How to Manually Compress PDF Size
Our Professional PDF Compressor gives you total control over your document size. Unlike basic tools, we offer:
- Live Preview: See the pixel quality of your document before you download.
- Manual Slider: Don’t settle for presets. Adjust compression from 1% to 100% to hit your target file size (e.g., under 100KB, 200KB).
- Real-time Calculation: See the estimated file size update instantly as you move the slider.
Steps for Best Results:
- Upload your PDF.
- Use the slider to lower the quality. Watch the “Estimated” size box.
- Check the “Live Preview” image on the right. Ensure text is still readable.
- Click Compress & Download.
Technique: This tool converts PDF pages to optimized JPEG images to achieve maximum size reduction that standard metadata cleaners cannot match.
