FastCompressor is a desktop app that makes image compression easy. It works entirely offline on your device. There is no uploading and no privacy concerns. You can drag and drop files or folders and reduce JPEG, PNG, or WebP sizes by up to 90 percent in seconds.

The interface stays simple even when compressing large batches. You can process hundreds of images at once. It comes with adjustable quality settings, resizing presets, and watermark options. Everything runs locally, so your files never leave your machine. That makes it ideal for designers, developers, or anyone handling sensitive visuals.

You can use a free version to test with batch size and feature limits. To unlock full capabilities, you pay once for the Pro version. Pro gives unlimited compression, faster speeds, and all future updates. Support for Windows, Linux, and Mac is built in. FastCompressor gives you speed, privacy, and control without subscriptions or accounts.
