Image Compressor
Reduce image file size before sharing or uploading. Images are processed in your browser and are not uploaded by this tool.
Compress an image
Note: Canvas re-encoding to JPEG may not preserve transparency. Keep the original file if transparency is important.
Why compress images?
Smaller image files can be easier to upload, share and store. The best compression setting depends on the image, its intended use and the quality you need.
Does compression always reduce file size?
No. Some images are already optimized, and re-encoding can occasionally produce a larger file. Compare the original and output sizes before using the compressed image.
Frequently asked questions
Are my images uploaded?
No. This tool uses browser-side image processing. It does not upload the selected image to the website.
Will the image quality change?
Lossy compression can reduce visual quality. Increase the quality setting if you notice unwanted artifacts.
