How Does PDF Compressor Work?
When you upload a file, it is sent over an encrypted HTTPS connection to our conversion server. The server reads the document structure (pages, text, images and fonts), applies the operation you selected, writes a new file and gives you a download link. The temporary files are then deleted automatically.
