Your PDF is already well optimized 👍
Re-compressing at this quality would have made it (larger than the original ), so we kept your original file untouched.
Tip: try the Balanced or Max Compression preset for a smaller file.

This tool re-renders each PDF page at an optimized resolution and rebuilds the document with efficient JPEG compression — the same approach desktop tools use, but running entirely in your browser via WebAssembly-grade JavaScript. Because nothing is uploaded, it works offline once loaded and your unreleased product files stay completely private.
Best for: image-heavy printables, puzzle books, planners, wall art, and Canva exports — these routinely shrink by 70–95%. Heads up: pages become high-resolution images, so text is no longer selectable in the output. For print-on-demand interiors (KDP), use the High Quality preset; for Etsy instant downloads, Balanced is the sweet spot under the 20 MB limit.
