Compress PDF
Reduce PDF file size while maintaining acceptable visual quality.
Overview
The Compress PDF tool reduces the file size of a PDF document by optimising images, removing redundant data, and applying efficient compression algorithms. This is essential for email attachments, web uploads, and reducing storage costs without significantly affecting the document's visual quality.
How to Use
- Navigate to Compress PDF from the Security & Optimization menu.
- Upload your file using drag-and-drop, Browse Files, or cloud storage (Dropbox / Google Drive).
- Select the compression level.
- Click Compress to process.
- Download the result when processing completes.
Options
| Option | Description |
|---|---|
| Compression level | Choose between Low (best quality, moderate reduction), Medium (balanced), or High (maximum reduction, some quality loss). |
Tips & Notes
Start with Medium compression and check the output quality. If the result looks good, try High for even smaller file sizes. If quality is critical (e.g., for print), use Low.
PDFs that contain mostly text will see smaller reductions than PDFs with many high-resolution images, where compression is most effective.
