About this tool
Reduce the byte size of your PDF documents. Choose between Lossless Structural Optimization (keeps selectable text and vector graphics while stripping unused objects and enabling PDF 1.5 object streams) or Strong Raster Compression (renders pages at controlled DPI and JPEG quality for maximum size reduction on scanned PDFs).
Note: Maximum Compression mode rasterizes pages into compressed JPEG streams, which removes text selectability in exchange for smaller file size on image-heavy documents.
