This browser-based compression rebuilds PDF pages
as optimized images. The resulting PDF may not retain
the original text selection/search functionality.
For normal scanned documents and image-heavy PDFs,
this can provide significant size reduction.

significantly from image-based compression.
Is my PDF uploaded to a server?
The compression process is performed locally in the

Will the compressed PDF remain searchable?

and text selection may not remain available in the
compressed output.
