Why are image files so large?
Modern smartphone cameras produce images at 4–12 MB by default, using minimal in-camera compression to preserve maximum detail. When you share these images via email or social media, the platform may apply its own compression — often reducing quality significantly. Using a dedicated tool like CompressFiles gives you full control over the quality-to-size tradeoff.
How much can you reduce an image's file size?
- Low compression — ~70% size reduction. A 5 MB image becomes ~1.5 MB. Near-original quality.
- Medium compression — ~85% size reduction. A 5 MB image becomes ~750 KB. Ideal for web and email.
- High compression — ~90% size reduction. A 5 MB image becomes ~500 KB. Maximum reduction with some quality trade-off.
