Frequently asked questions
How does PDF compression work here?
Pages are re-saved as optimized images to shrink the file, which works best on scans and image-heavy PDFs.
Will the text stay selectable?
Because pages are rasterized, text becomes part of the image and is no longer selectable.
Are my files uploaded?
No. Compression runs locally.
