Frequently asked questions
How do I compress a PDF to 300 KB?
Add the PDF, keep the pre-set 300 KB limit and click Compress PDF. Check the size shown next to the download button.
Is 300 KB enough for a 10-page document?
Often yes for text documents. Ten scanned colour pages may need black & white mode to stay sharp.
How do I reduce a PDF to 200 KB (or 100 KB)?
Add your PDF, choose "Exact size (KB / MB)", type 200 (or 100) and click Compress PDF. The tool tries different quality settings and gives you the best-looking version that fits under your limit.
Which compression level should I choose?
Recommended works for most files. Choose Extreme if you need the smallest possible size, Light if you must keep text selectable (for example a contract), or Exact size when a website gives you a maximum file size.
Why can't I select text after compressing?
The Recommended, Extreme and Exact size levels save each page as an optimised image — that's what makes scans and photos so much smaller. If you need selectable text, use the Light level.
