Need to compress a PDF for email, uploads, or sharing? LitePDF Pro reduces PDF file size in your browser. Choose Extreme, Recommended, or Less compression, then download a smaller PDF without creating an account.

Managing digital documents efficiently is vital for modern professional and academic success. Whether you are dealing with multi-page contracts, financial spreadsheets, academic manuscripts, or high-resolution image scans, Compress PDF online free on LitePDF Pro provides a reliable, lightning-fast solution. Built on high-performance in-memory workers, our tool eliminates the hassle of purchasing expensive software licenses or waiting for slow desktop installations.

Large PDFs are a common problem: email providers reject attachments, forms refuse uploads, and shared drives fill up quickly. Our free PDF compressor rebuilds heavy pages and optimizes images so the file gets smaller while staying readable.

Use Recommended compression for everyday documents, Extreme when size matters most (presentations with many photos), and Less compression when you want maximum quality.

After compressing, you may also want to merge PDF files, convert PDF to JPG, or password protect PDF before sending.

Unlike traditional desktop programs that take up storage space and require complex updates, LitePDF Pro executes Compress PDF online free entirely through your browser. Your formatting remains intact, fonts stay sharp, and visual layout is preserved perfectly from start to finish.
