How does PDF compression work?
Our compressor optimizes images inside the PDF, removes duplicate data, and compresses fonts. You can choose compression level from basic to maximum.
Will I lose quality?
Basic compression preserves near-original quality. Higher compression levels may slightly reduce image quality within the PDF to achieve smaller file sizes.
Is there a file size limit?
PDF files up to 50MB are supported.
Is it free?
Yes. PDF compression is completely free with no registration required.
How much can I compress a PDF?
Compression rates vary depending on the PDF content. Text-heavy PDFs may compress 10-30%, while image-heavy PDFs can be reduced by 50-80% on higher compression settings.
Are my PDF documents secure?
Yes. All uploaded PDFs are automatically deleted from our servers after 1 hour. We never store or share your documents.
What compression levels are available?
You can choose from Maximum Quality, Medium Quality, Basic Compression, and Maximum Compression. Higher compression produces smaller files but may reduce quality.
