PDF Compressor is a compact Android utility that reduces PDF file sizes while keeping text legibility and image quality intact. PDF Compressor compresses bulky PDFs with one tap and offers adjustable optimization levels so you can balance file size and fidelity. All processing happens locally on your device, and the interface is built with Jetpack Compose and Material 3 for a smooth experience.

Key Features

Fast one-tap compression makes it easier to store and share large documents. Advanced scanned-document processing powered by OpenCV uses 1-bit binarization filters to clean scanned pages, enhance contrast and remove noise. Flexible compression levels (Low, Medium, High) let you choose the right balance between file size and visual fidelity. Local processing keeps sensitive documents private and offline.

Advantages

PDF Compressor reduces file size significantly while preserving text clarity and acceptable image quality. The simple workflow speeds up preparing documents for email or messaging. Cleaning and binarization improve readability of scanned pages and reduce visual noise.

Disadvantages

1-bit binarization filters may not be suitable for color-rich photographs and can convert images to black-and-white. Aggressive compression settings can reduce image fidelity, so results vary depending on the original file. The app focuses on local processing and does not include cloud-based upload or remote backup features.
