Why Compress PDFs?
PDF files can sometimes be very large, especially those containing high-resolution images or detailed graphics. Compressing PDFs can be highly beneficial in reducing file sizes, making them easier to store and share.
Large PDFs can also take up significant storage space on your device, making it difficult to store additional files. Compressing these PDFs can free up storage space, allowing you to keep more files on your device.
How Does the PDF Compressor Function?
Our tool utilizes advanced compression techniques to reduce the size of PDF files. It intelligently analyzes the content of your PDFs to achieve the best possible compression while maintaining quality.
To start, upload the PDFs you want to compress. You can upload multiple PDFs at once, and our server will handle the compression for each file.
Click the "Upload Files" button and select your PDFs. Once uploaded, thumbnails of your PDFs will appear in the queue, showing real-time progress as they are analyzed and compressed.
Our server automatically determines the optimal compression rate to minimize file size while preserving quality. When the compression process is complete, you can download the compressed PDFs individually or as a ZIP file containing all compressed PDFs.

Is It Safe to Compress PDFs?
Rest assured, our free service is safe. Your original files remain untouched on your device, so if you're dissatisfied with the compressed results, you can retry. Additionally, our automated system deletes all data after six hours, ensuring the security of your information.
