An image compressor reduces the size of supported image files using the available compression settings. GlobalToolHub's free browser tool lets you select an image, adjust the settings, and download the result. Compare the output with the original before replacing it, because compression can change image quality and may not always produce a smaller file.
How to Compress an Image
1. Select a supported image.
2. Adjust the available quality settings.
3. Process the image.
4. Compare the file size and appearance, then download the result.
Worked example

Results depend on the source image, output format, and quality settings. Keep an original copy; compression is not guaranteed to improve every file.
