Frequently Asked Questions

How much can my PDF be compressed?

Compression rates vary, but most PDFs are reduced by 50-80% while maintaining readable quality.

Will compression reduce image quality?

We optimize the balance between file size and quality. Text remains sharp, and images stay clear at normal viewing sizes.

Can I compress multiple PDFs at once?

Yes, you can add multiple files and compress them in batch for maximum efficiency.

Why is my compressed PDF barely smaller than the original?

Some PDFs are already well-optimized and contain minimal metadata or redundant data to strip. PDFs that were exported from modern tools like Adobe Acrobat or Chrome's print-to-PDF often leave little room for further compression.

Is the compressed PDF compatible with all PDF readers?

Yes. The compressed output is a standard PDF file that works with any PDF reader including Adobe Acrobat, Preview on Mac, Chrome's built-in viewer, and all mobile PDF apps. No special software is needed to open it.
