Frequently asked questions
Why can’t I select text after compressing?
Strong compression rebuilds pages as images, which removes selectable text and links. Keep the original if you need them.
Why did the size barely change?
Text-only PDFs are already compact. Compression helps most with scans and photo-heavy files.
