Fast, secure and free. Files stay in your browser.
Free online tool by ScanPatra. Secure processing. No signup required.
Reduce your PDF file size instantly in your browser. No upload to server, no signup, no watermark.
Upload your PDF files, choose a compression level, and click Compress. Compression happens entirely in your browser using pdf-lib — your files are never sent to any server.
Note: PDFs that are already optimized (text-only, small files) may see little reduction. Scanned documents and image-heavy PDFs compress best.
