PDF Compressor

Lossless Optimization: Our tool removes unnecessary data, unused objects, and optimizes the PDF structure without affecting visual quality.

Metadata Removal: Removes document properties, author information, and keywords that aren't needed for viewing.

Object Cleanup: Removes unused PDF objects and optimizes the internal structure for smaller file size.

Image Optimization: Compresses embedded images while maintaining acceptable visual quality.

Adjustable Quality: You can control the compression level from minimal (best quality) to maximum (smallest size).

Visual Impact: At balanced settings (70% quality), most PDFs show minimal visual difference while achieving significant size reduction.

Text Preservation: Text content and fonts are preserved without quality loss. Compression mainly affects images and metadata.

Non-destructive: The original PDF file remains unchanged. You can always go back to the original if needed.

Typical Results: Most PDFs can be reduced by 20-50% depending on content and original optimization.

Image-heavy PDFs: Documents with many images can see 60-80% size reduction with aggressive compression.

Text-only PDFs: Already optimized text documents may see smaller reductions (10-30%) as they're already efficient.

Large Files: Larger PDFs typically achieve better compression ratios than smaller, already optimized files.

Local Processing: All compression is done directly in your browser. Your PDF files never leave your computer.

No File Upload: Files are not uploaded to any server. Processing happens entirely on your device.

Complete Privacy: Your sensitive documents remain completely private and secure throughout the process.

Temporary Processing: Files are only held in browser memory during compression and are automatically cleared when done.

Scanned Documents: PDFs created from scanned images typically achieve the highest compression ratios.

Presentations: PDFs with slides, charts, and graphics often compress very well.

Mixed Content: Documents combining text, images, and graphics benefit significantly from compression.

Pre-optimized Files: Some PDFs are already optimized and may show minimal size reduction.
