Compress JPG, PNG, and WebP Images
Reduce image file size for websites, email and social media. Everything runs on your device using the browser Canvas API, so your images are not uploaded to ToolZone.

Compress an image and check the result
- Choose one or more images. Select JPG, PNG, WebP, or the original format.
- For JPG or WebP, start with a moderate quality setting and click Compress Images.
- Compare the output size and open the downloaded copy at full size. Keep your original if the new file is larger or visibly degraded.
Example and limits
For example, a 2400-pixel-wide photo stays 2400 pixels wide here. Use Image Resizer first if you also need smaller dimensions.
Does the quality slider affect PNG?
No. Canvas PNG export does not use the lossy quality setting. Re-encoding can produce a larger file. JPG removes transparency; this tool fills transparent areas with white. Animated images are exported as a still image.
