Reduce PDF file size by adjusting quality and resolution. See the compression ratio before downloading. Free and private.
Select your PDF file. The original file size is shown immediately.
Choose image quality (10–90%) and render resolution. Lower values = smaller file.
See original vs. compressed size and % reduction. Download your optimized PDF.
Each PDF page is rendered to a canvas at your chosen resolution, then saved as a JPEG image at your chosen quality. The resulting PDF contains compressed images instead of the original vector content.
The compressed PDF uses rasterized images, so text will not be selectable. For purely reducing file size while keeping vectors, compression ratios may be lower.
This can happen if the original PDF was already well-optimized or has low page count. Try lowering quality or resolution further.
