Why Compress PDFs?

Large PDF files can be problematic for sharing and storage. Compressed PDFs offer several benefits:

  • Easier email attachments - Most email providers limit attachment sizes to 25MB.
  • Faster uploads - Smaller files upload quicker to cloud storage and websites.
  • Save storage space - Compressed PDFs take up less space on your device.
  • Faster downloads - Recipients can download your files more quickly.

Frequently Asked Questions

How much can PDF files be compressed?

PDF compression typically reduces file sizes by 20-60% depending on the content. PDFs with many images compress more than text-heavy documents.

Will compression affect PDF quality?

Text and vector graphics remain sharp. Image quality may be slightly reduced depending on your compression settings, but is usually not noticeable.

Are my PDFs uploaded to a server?

No. All compression happens directly in your browser. Your PDFs never leave your device, ensuring complete privacy and security.

Can I compress password-protected PDFs?

Password-protected PDFs may not compress correctly. For best results, remove the password protection before compressing, then re-add it after.

What does 'Remove images' do?

This option strips all images from the PDF, leaving only text and vector graphics. Useful for creating lightweight text-only versions.

What does 'Remove metadata' do?

This removes author name, title, creation date, and other metadata from the PDF. Useful for privacy when sharing documents.
