Frequently Asked Questions

How much can PDF compression reduce file size?

Typically 20-50% for PDFs with embedded images. Text-heavy PDFs see smaller reductions (5-15%) since text is already compact.

Does compression affect PDF quality?

FileCurve uses lossless object stream optimization. Text and vector graphics stay perfect. Embedded images are not re-compressed.

How to compress PDF under 1MB?

Upload and compress. If still over 1MB, the PDF likely has high-resolution images. Try compressing images separately first, then re-creating the PDF.
