Free website image optimizer
Make the photo smaller. Keep the useful detail.
Resize and compress a website image on this device. Compare the actual file sizes before downloading—because a different format is not automatically a smaller file.
The image stays on this device. It is processed in your browser and is not uploaded or saved.
01
Choose the image and output
The tool never enlarges a smaller source image.
Keep the original file. This creates a separate optimized copy.
02
Compare before downloading
Look at both clarity and file size—not the percentage alone.
Choose an image to see the real before-and-after size.
This browser conversion removes most embedded metadata. Compare the downloaded image visually before replacing anything on a website.
