Compress PDF files online
Use this PDF Compressor to make a PDF file smaller for email attachments, website uploads, online forms and document sharing. Choose your PDF, select a compression level, and download a new smaller copy. Your original PDF stays unchanged.
How it works
Drop a PDF into the box or choose one from your device. Pick the compression level that suits your file, click Compress PDF, and download the result when it is ready.
Which compression level should I choose?
Choose Balanced for most PDFs. Choose Maximum when the smallest possible file is more important than image detail. Choose High quality when your PDF contains small text, diagrams or images that need to stay clear.
Questions people ask
Will this change my original PDF?
No. The tool creates a separate compressed PDF for you to download.
Is my PDF stored?
No. It is used only to create the compressed file and then deleted from the server.
Will every PDF become much smaller?
Not always. PDFs that are already compressed may have little room left to reduce in size.
