The uploaded file format is already matching the requested conversion format. Compression will still apply.
WebP compression preserves alpha transparency channel presets. Converting transparent PNGs to JPEGs will discard transparency backgrounds.

Result
Lower quality gradually until the file is small enough while faces, text, and important edges still look clean.
Before you rely on the result

Limits and checks

  • The smallest file is not always the best result; excessive compression can introduce visible artifacts.
  • Already optimized images may show little additional reduction.
  • Keep the original because repeated lossy compression can progressively reduce quality.
Specific guidance

Image Compressor questions

What quality setting should I use?

There is no universal value. Start high, reduce it gradually, and judge the image at the size where it will be used.

Why is my file not much smaller?

The source may already be compressed, or its content and format may not respond strongly to the selected setting.

Is the original image modified?

No. The tool creates a new downloadable result and does not overwrite the source file on your device.
