Compressing PDF files helps reduce storage space and makes sharing documents easier. Our free PDF compressor applies basic optimization techniques to reduce file size while maintaining acceptable quality. The compression works by optimizing the internal document structure and reducing embedded image quality where possible. All processing happens locally in your browser — your files are never uploaded to any server. Please note that this is a basic client-side compression tool. Results may vary depending on the content of your PDF. Documents with many high-resolution images will see the most significant size reduction. Text-heavy documents may see minimal changes. For advanced compression with more options, server-side processing would be needed, which we plan to add in a future update. This tool is perfect for quickly reducing file size for email attachments or web uploads.
