Compress PDF

This free PDF compressor helps you reduce file size quickly for email, sharing, and uploads. Whether you're working with large scanned documents or image-heavy PDFs, the tool optimises file structure and compresses images efficiently while keeping text sharp and readable.

No signup required, no watermark added, and no usage limits. Files are securely processed and automatically deleted after compression.

This tool reduces PDF file size by compressing images, removing redundant data, and optimising internal structure. It uses industry-standard compression techniques to balance file size and readability.

Choose between different compression levels depending on your needs — whether you want the smallest possible file or better visual quality for printing.

1. Upload your PDF — drag & drop or select your file.

2. Choose compression level — maximum, balanced, or minimal.

3. Download compressed file — ready instantly after processing.

Compression results depend on your PDF content. Files with large images typically shrink significantly, often by 50–80%. Text-based PDFs or already optimised files may see smaller reductions.

Choosing a higher compression level reduces size more aggressively, while lower compression preserves visual quality for printing or archiving.

• Send PDFs via email without hitting attachment limits
• Upload documents to websites with file size restrictions
• Share files faster over slow connections
• Reduce storage space for large document libraries
• Optimise PDFs for web viewing

Maximum: Smallest file size. Best for email and web use.

Balanced: Good mix of quality and size. Recommended for most users.

Minimal: Highest quality. Best for printing.

Your files are encrypted during upload and processing. Compression is handled securely on our servers, and files are automatically deleted immediately after completion.

We do not store, share, or access your documents beyond the compression process.

Most PDFs compress within seconds. Very large or complex files may take longer depending on size and content.

For best results, use balanced compression for general use and maximum compression for large scanned documents.
