PDF Shrinker — Target Under 5 MB

Drop in one PDF. This tool rebuilds it as a lighter PDF by rasterizing pages and compressing them. If the whole file still cannot fit under the target, it automatically creates multiple numbered PDF parts, with each part kept under the size limit.

Best for scanned/image-heavy PDFs. Text-selectable content will usually become image-based after compression.

Waiting for a PDF.

This tool aims for a file under the limit. For very large or very long PDFs, the combined output may not fit under the target without making pages unreadable. In that case, the tool switches to multi-part output so each PDF stays under the chosen size.

Runs in your browser. No upload to a server. Uses PDF.js for reading, PDF-Lib for rebuilding, and JSZip for bundled downloads when split output is needed.
