No. Picxor processes all files entirely in your browser using JavaScript. Your files never leave your device and are never uploaded to any server.
Screen quality re-renders pages at 72 DPI - best for reading on screen, smallest file size. eBook quality uses 150 DPI - good balance of size and clarity. Print quality uses 300 DPI - suitable for printing. Prepress mode only optimizes without re-rendering, preserving maximum quality.
PDFs with mostly text compress very little since text is already compact. PDFs are hardest to compress when they contain already-compressed images or were previously compressed. If the output is not smaller, the tool shows a warning but still lets you download. Try a lower DPI setting.
Picxor can handle files up to 100MB. Very large files may take longer as processing happens in your browser. For files over 50MB, closing other browser tabs helps.
