About Image Compressor

Image compression reduces file size by recompressing image data at lower quality levels. This tool uses Canvas API to reprocess images, letting you balance file size against visual quality. Typical savings: 40-70% with minimal perceptible quality loss.

Compression is "lossy" for JPG/WEBP (some quality lost permanently) and "lossless" optimization for PNG (removes unnecessary metadata). All processing happens in your browser, images never upload to servers, protecting personal photos and proprietary designs.

Size reduction varies by image content: photos compress well, graphics/screenshots less so. Experiment with quality settings to find acceptable tradeoffs for your use case.

Frequently asked questions

Typical photo compression achieves 40-70% size reduction with minimal visible quality loss at 80-85% quality. Graphics and screenshots may compress less effectively. Results vary by image content.

No. This tool compresses file size while maintaining pixel dimensions. To reduce dimensions, use the image converter tool which offers resizing options.

For PNG, the tool can strip metadata without affecting pixels. For JPG/WEBP, any recompression is lossy, you always sacrifice some quality. Higher quality settings minimize loss but reduce size savings.
