Target size mode renders each page as an image, so text can no longer be selected or searched. Very small targets lower the image quality.

FAQ
What is the difference between light compress and target size?
Light compress rewrites the PDF with tighter object streams and tries to keep text selectable. Target-size mode re-encodes pages as images to aim for a KB or MB goal, which usually shrinks more but turns text into pictures.
Will text stay selectable after compression?
In light mode, text usually remains selectable. In target-size mode, pages are rendered as images, so you can no longer select or copy the original text layer.
Can I shrink a PDF for email or form uploads?
Yes. Use light compress when a modest size drop is enough, or set a target size when a portal or mailbox needs a stricter cap. Results vary with how image-heavy the PDF already is.
Is my data private?
Yes. Compression happens on your device. The PDF is not sent to a server to reduce its size.
