💡 Pro Tip:
Choose "Balanced" compression for most documents as it offers a good mix of quality and file size reduction. Use "Maximum Compression" for PDFs that contain mostly text, and "Less Compression" for PDFs with high-quality images that must be preserved.
Depending on the content of your PDF and the compression level you choose, you can reduce file size by 30-90%. Documents with many images typically see the largest reduction.
Free users can compress files up to 50MB. Premium users can process files up to 200MB with additional compression options.
The impact on quality depends on the compression level you choose. 'Low' quality provides maximum compression but may visibly reduce image quality. 'Medium' offers a good balance, while 'High' preserves most of the original quality with more modest size reduction.
