Frequently Asked Questions

How much can I reduce my PDF size?

Compression depends on your PDF content. Image-heavy PDFs can be reduced by 50-80%, while text-only PDFs may see smaller reductions.

Will compression affect PDF quality?

You can choose compression levels. High compression reduces file size more but may reduce image quality slightly.

Are text and fonts preserved?

Yes. Text content and fonts are preserved. Only embedded images are compressed to reduce file size.
