About this tool
WhatsApp lets you send fairly large documents, but recipients on mobile data appreciate a lean file that downloads in seconds. A ~1 MB PDF opens quickly on any phone and travels well through group forwards. This landing pre-tunes the PDF compressor for that target and pairs it with a preview so you can confirm readability before sharing. Files are processed inside your browser and never leave your device.
