Compression behavior (Auto)

If the target cannot be reached by quality alone, dimensions are reduced automatically.

Compression always keeps the original proportions unless a future crop tool changes them.

Frequently Asked Questions

Can I compress an image to an exact KB size?

The tool aims for your chosen KB limit or slightly below it. The final size can vary by a few bytes because JPG, PNG, and WebP encode each image differently.

What if my image is already under the target size?

You may not need to compress it. Compare the original and result sizes before downloading so you do not reduce quality without a reason.

How does the image compressor reach a low KB limit?

It first adjusts image quality. If that is not enough and resizing is enabled, it also reduces pixel dimensions while keeping the aspect ratio.

Are my images uploaded to a server?

No. The image is read, compressed, and downloaded in your browser. It is not sent to our server.
