Compress PDF

Compress PDF reduces the size of your PDF file so it fits inside email attachment limits, uploads faster, and takes less storage. Drop in your file, click Compress, and download a smaller version of the same document. The tool runs entirely in your browser. Your PDF is never uploaded to a server, which makes it safe for confidential documents like contracts, invoices, scanned IDs, and tax forms. We don't see, store, or log any of the files you compress. How much you save depends on what's in the PDF. Text-heavy documents (reports, ebooks, manuscripts) compress well — often 20–40% smaller. PDFs that are mostly scanned images see smaller gains because the images are already encoded. For image-heavy PDFs, the highest-impact step is usually compressing the source images first, then merging them back into a PDF. Common uses include shrinking a PDF to fit a 10 MB or 25 MB email cap, reducing a portfolio so it loads quickly, and trimming a long scanned document before uploading to a portal that limits file sizes.
