About the Compress PDF
Compress PDF makes documents smaller so they are easier to email and upload. The basic level optimizes the file structure and keeps text selectable, while the medium and strong levels convert pages to compressed images — ideal for scanned documents. You always see the size before and after.
How to use the Compress PDF
- Choose the PDF file you want to compress.
- Pick a compression level: basic, medium or strong.
- Click "Compress PDF" and download the smaller file if the result suits you.
Frequently asked questions
Which level should I choose?
Start with Basic for text documents. For scanned pages or image-heavy PDFs, Medium usually gives the best balance of size and readability.
Why did my file not get smaller?
Some PDFs are already optimized. In that case the tool tells you so instead of returning a larger file.
