Reducing a PDF’s file size can make it easier to store or share, and the options here vary in their controls and limits. Compare compression modes and batch compression, then check maximum file size and whether an offline desktop app fits your workflow. API access and supported platforms can help you assess how a tool might fit alongside other software; free-plan availability and paid-from pricing give you access details to weigh. PDF2Go and PDFOptim lead the entries, with Xodo Compress PDF and FS PDF Compressor also near the top. Use those listed comparison points to narrow the options to the documents and working setup you have in mind.
