    What is image compression?

    Image compression reduces file size by removing redundant data while preserving visual quality. Lossy compression (JPEG) achieves 60–80% size reduction with minimal perceptual difference — ideal for web, social media, and email.

    Pages with optimized images load 3.5× faster on average [HTTP Archive, 2024]. Compressed images reduce bandwidth costs by up to 70% [Cloudflare, 2024].

    Trndinn's compressor uses smart algorithms to find the optimal quality-size balance. Everything runs in your browser — images never leave your device.
