Compress a PDF to 300 KB
Meet a 300 KB upload cap without uploading your file first.
Some government and application portals cap documents at 300 KB, a middle ground between the tight 100 KB limits and the roomier 500 KB ones. This tool targets 300 KB as soon as you add a file and shrinks it on your device, so nothing is uploaded.

Why compress on your device
Documents you upload to portals often contain personal details. Compressing in the browser means the file is never sent to a compression service, so there is no extra copy on someone else’s server.
