Why compress a PDF?
Email & Upload Limits
Most email providers cap attachments at 10–25 MB. Compressing a PDF helps it fit within limits without reuploading elsewhere.
Faster Sharing
Smaller PDFs upload and download faster on any connection — especially critical for mobile users and slow networks.
Storage Savings
Archives of thousands of PDFs shrink dramatically with compression — reducing cloud storage costs and backup times.

Frequently Asked Questions
What compression techniques are used?
VisualDocs uses PDF object stream compression and metadata removal. For maximum reduction, select Extreme which also removes annotations.
Will the PDF still be readable after extreme compression?
Yes — text and vector elements are lossless. Only embedded images may see slight quality reduction at extreme levels.
What if the output is larger than the original?
If compression produces a larger file, the original is returned automatically. This can happen with already-optimized PDFs.
Does compression remove passwords or encryption?
No. Compression does not modify security settings. Encrypted PDFs remain encrypted after compression.
