About PDF Compression
This tool compresses PDF files by converting pages to optimized images. All processing happens in your browser for maximum privacy and security.
Features:
- • Upload up to 10 PDF files at once
- • Maximum 100 MB per file
- • Batch compression with individual progress tracking
- • Download all compressed files as a ZIP archive
- • Multiple compression levels (low, medium, high, custom)
- • Real-time compression statistics
How it works:
- • Renders each PDF page to a canvas
- • Applies image compression with quality settings
- • Optionally resizes images to reduce file size
- • Removes metadata to save additional space
- • Creates a new optimized PDF with compressed images
Compression Levels:
- • Low: 90% quality, minimal compression (~10% reduction)
- • Medium: 75% quality, balanced compression (~30% reduction)
- • High: 60% quality, maximum compression (~50% reduction)
- • Custom: Fine-tune all compression settings manually
Best suited for:
- • PDFs with large images or scanned documents
- • High-resolution PDFs that need to be shared via email
- • Documents where file size is more important than perfect quality
- • Batch processing multiple PDF files at once
Limitations:
- • Text becomes non-selectable (converted to images)
- • Already optimized PDFs may not compress further
- • Text-only PDFs may not see significant compression
- • Very large PDFs may take longer to process
Privacy: All compression happens in your browser. Your PDF files are never uploaded to any server. Everything is processed locally for maximum security.
