How to Compress a PDF
- Upload a PDF file using the drop zone or file picker.
- View the file analysis and adjust compression quality and render scale.
- Click "Compress PDF" to re-export at lower quality.
- Download the compressed PDF file.
How It Works
This tool renders each PDF page to a canvas and re-exports it as a JPEG-compressed PDF. This is most effective for image-heavy PDFs. Text-only PDFs may not see significant size reduction. Adjust the quality slider lower for more compression, or increase the render scale for better visual quality.
