Reduce Image Size Online Free

For websites, compress images to 70-80% quality and resize to the maximum display width (often 1200-1920px). This typically reduces file sizes by 60-80% while maintaining visual quality on screen.

Most social platforms re-compress images anyway, so uploading pre-compressed files helps maintain quality. Use 80-85% quality and resize to the platform's recommended dimensions (e.g., 1080x1080 for Instagram).

The most effective approach combines three strategies: reduce quality (80% is usually invisible), resize dimensions (match the display size), and choose the right format (JPEG for photos, PNG for graphics with transparency).

On average, you can reduce image file size by 50-80% with our compressor. The exact reduction depends on the image content, original quality, and your chosen compression settings.
