Frequently asked questions
How does it compress PDFs?
Pages are re-rendered as optimized images at your chosen resolution and quality, which removes redundant data and shrinks the file. Text is turned into image content.
Will my text stay selectable?
No. Because pages are rasterized, text becomes part of the image. If you need selectable text, use a lower compression level or keep the original.
By how much will my file shrink?
It depends on the content. Image-heavy or scanned PDFs often shrink dramatically; simple text PDFs shrink less.
