About PDF Compress
Compress a PDF online with this free PDF compressor that runs in your browser. Upload a file, choose Strong, Medium, or High quality, and download a smaller copy when the new size is lower than the original. Strong aims for the smallest file. High keeps more detail. Medium is a balanced default. Pages are redrawn as compact images so scans and photo-heavy PDFs shrink the most. Nothing is uploaded to a server.
Reducing PDF size helps when email rejects a large attachment, when a portal has an upload cap, or when you want faster sharing on chat. Photographers shrink scanned albums. Students compress assignment packs. Offices shrink statements before they archive them. The page shows original versus compressed size so you can see how much was saved.
Pick a PDF within the size and page limits, compress, and download. If Strong still does not shrink the file, the document may already be optimized or mostly text at a small size. Password protected PDFs should be unlocked first. After compressing you can merge, split, or lock the result with the other PDF tools.
Compression happens locally on your device, so the original file never leaves your browser. Use this free compress PDF tool, reduce PDF size utility, and PDF optimizer whenever you need a smaller PDF without sending it to a website.
