How to Compress an Image
- Click the upload area or drag and drop your image file.
- Adjust the quality slider — lower values produce smaller files, higher values preserve more detail.
- Click Compress Image.
- Review the original size, compressed size, and percentage saved.
- Download the compressed image.
Tips and Best Practices
- A quality setting of 75-85% typically offers the best balance between file size and visual quality for most photos.
- For web use, aim for images under 200 KB — this significantly improves page load speed.
- PNG images with large areas of solid color often compress very well. Photographs with many colors benefit most from JPEG compression.
- Check the preview after compressing to make sure the quality is acceptable before downloading.
- If the compressed file is still too large, try lowering the quality slider further or resizing the image dimensions first.
