Frequently asked questions
These answers cover the questions people usually have before compressing a file.
Can I compress PDF to 200KB or 500KB?
Yes. Those are common target sizes for forms and email, and this page is built to help you aim for them directly.
Will my PDF always look the same?
Not always. Strong PDF reduction can soften text and graphics, especially when the file needs to become much smaller than the original.
What kinds of PDFs compress best?
Scanned documents and image-heavy PDFs often benefit the most, while vector-rich or already optimized PDFs may have less room to shrink.
