Compress PDF

Shrink PDF file size (server, Ghostscript)

Server processing: compression is the one PDF operation that browsers genuinely can't do well — it requires Ghostscript. Your file is uploaded to Toolenza, processed, returned, and deleted the moment your download starts. We never persist a copy.

About Compress PDF

A PDF compressor reduces file size by re-encoding embedded images, stripping redundant metadata, and de-duplicating objects. Large image-heavy PDFs typically shrink 50-80% with minimal visible quality loss; text-only PDFs are already near-optimal.
