Large PDFs slow down sharing and often hit attachment limits. Our free Compress PDF tool reduces file size by optimizing embedded images and structure so your document stays clear enough to read and print.
Compress PDF is a free online PDF compressor that shrinks large PDF files while keeping text and images readable. Use it when email, WhatsApp, or upload forms reject oversized documents.
Ideal for scanned contracts, presentations, portfolios, and multi-page reports that need to travel lightly across email or messaging apps.
Compression focuses on practical everyday sharing — no paid plan, no watermark, and no desktop suite required. After compressing, you can still merge, split, or rotate the same file with our other PDF tools.
Compression reduces size mainly by optimizing images. Text usually stays sharp; very heavy compression can soften photos. Use the smallest size that still looks good for your use case.
