PDF Compressor is a minimalist, on-device utility designed to shrink oversized PDF files. Whenever you encounter upload limits during exam registrations, certificate submissions, visa applications, job applications, or email attachments, our app helps you easily compress PDFs down to 500KB, 1MB, 2MB, 5MB, or any custom target size. Since the entire compression engine runs locally on your device, no internet is required, and your sensitive contracts, invoices, or personal profiles will never leave your phone. Strictly ad-free and without any tracking SDKs.
