Choose the right balance of quality and file size:

Maximum Compression (High):

• Best for: Large files, email attachments, web sharing
• Smallest output size with visible quality reduction

Balanced Compression (Medium - Default):

• Best for: General use and most documents
• Good balance of quality and file size

Best Quality (Low):

• Best for: Print-ready documents, presentations
• Minimal compression, maximum quality retained

Yes, batch compression is available:

• Upload up to 2 PDF files simultaneously
• Select the same compression level for all files
• Track progress for each file individually
• Download all results as a single ZIP archive

Best practices:

• Each file respects the 200MB upload limit
• Process similar document types together
• For large batches, split into groups of 2

Compression results depend on your PDF content:

Image-Heavy PDFs (scans, brochures):

• High compression: 50-75% reduction
• Scanned documents compress extremely well

Mixed Content PDFs (text + images):

• High compression: 40-60% reduction
• Text remains vector quality, images get optimized

Text-Only PDFs:

• 10-25% reduction typically
• Text already compresses efficiently in PDFs

Already compressed PDFs:

• 0-10% additional reduction
• Consider removing unused pages instead
