Compress PDF
Reduce PDF file size by removing metadata, using object streams, and flattening forms — all processed locally in your browser.
Browser-side PDF compression is limited compared to server-side tools. Results depend on PDF content — documents with embedded images may see minimal size reduction. Metadata removal and object stream optimization work best on text-heavy PDFs.
