Large images slow down websites, eat up storage, and the wrong format causes compatibility issues. This tool lets you compress AND convert in one step — reduce file sizes while switching between PNG, JPG, and WEBP. All processing happens in your browser; your files never leave your device.
How it works
🔒
Privacy first: Compression runs entirely in your browser — files never leave your device. No servers, no uploads.
⚖️
Adjustable quality: Use the slider to find the perfect balance between file size and image quality.
🔄
Format conversion: Change formats while compressing. PNG → JPG for smaller files, JPG → PNG for transparency, and more.

Quick answers
📦 What happens to transparency in JPG?
JPG doesn't support transparency. When converting PNG with transparency to JPG, we add a white background automatically.
✨ Which format is smallest?
WEBP typically gives the smallest files at similar quality, followed by JPG. PNG is largest but lossless.
🔐 Are my images stored?
Never. All processing happens locally on your device. Your images are never uploaded to any server.
