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.
Can I compress a scanned PDF or image-based PDF?
Yes. Our compressor works on all PDF types including scanned and image-based PDFs. Image-heavy PDFs typically see the biggest size reduction, 50-80% on higher compression settings.
What compression level is best for email attachments?
For email, we recommend Basic or Medium compression. These levels reduce file size significantly while keeping the document readable and clear. Most files under 50MB will shrink below common email attachment limits (25MB).
Does compressing a PDF affect the text and font quality?
Text remains sharp at all compression levels. At higher compression settings, images embedded in the PDF may show slight quality reduction, but text and fonts are always preserved clearly.
