How much smaller will my PDF be?

Varies significantly by file content. Metadata-heavy PDFs may shrink 20-40%. Image-heavy PDFs may see only 5-10% reduction. Text-only PDFs often see 15-25% reduction.

Will compression affect text readability?

No. Text is not re-encoded during compression — only structural overhead is removed. Text quality is preserved identically.

My PDF barely got smaller — what can I do?

The file is likely large due to high-resolution embedded images. For aggressive image compression, use Ghostscript on the command line.
