PDF Compress

Reduce PDF file sizes with our PDF Compress tool. Compress PDFs by downscaling pages and re-encoding images at your chosen DPI and JPEG quality settings. Perfect for reducing large scanned documents, photo-heavy PDFs, or files that are too big to email. Select your target DPI (72-300), adjust JPEG quality (1-100), and optionally convert to grayscale for maximum compression. The tool renders each page at your specified settings and rebuilds a smaller PDF. All processing happens locally in your browser using pdf-lib—no uploads, complete privacy. Note that this compression method rasterizes pages, so text becomes non-selectable. Great for archiving, email attachments, or reducing storage space. Download your compressed PDF instantly and use it anywhere.
