Compress PDF Files

PDFs generated from design tools, scanned documents, or exported presentations are often far larger than they need to be. A 40MB PDF from an InDesign export or a scanned document with embedded images can fail to upload to a portal, exceed an email attachment limit, or take minutes to open on a slow connection.

The compress skill reduces PDF file size by optimising embedded images, removing unnecessary metadata, and applying modern compression to the document structure. The output is a smaller file that opens identically in any PDF reader.

Legal teams sending large filing packages, businesses distributing product catalogues, and anyone submitting documents to government portals with file size limits use this to get files to an acceptable size without printing and rescanning.
