Compress PDF
Compare original and output sizes before downloading. Processing stays in your browser.
No PDF selected.
Important: Image-based compression rasterizes every page. Searchable/selectable text, forms, links, signatures, layers, accessibility tagging and vector fidelity may be lost. Do not use for signed or legally sensitive documents. Keep your original.
Structure optimization may not reduce an already optimized PDF. No saving is claimed unless the output is actually smaller.

All PDF bytes are processed locally in your browser. The processing libraries load from a third-party CDN, so an internet connection is required. Password-protected and malformed PDFs may be unsupported. Very long documents may use substantial memory. The original file is never overwritten.
