No account. No upload. No waiting.
Your Files Never Leave
Your Browser
PDFCompressor runs Ghostscript entirely in WebAssembly inside your browser tab. When you drop a file, it goes from your disk to your browser's memory, gets compressed there, and comes back to your disk. Our servers are never involved in that process. Not even for a millisecond.
