Frequently Asked Questions

Is this Image Size Reducer free?

Yes. You can use the tool for free without creating an account.

Which image formats are supported?

The tool supports JPG, PNG and WebP images up to 20 MB.

Will the output always match the exact target size?

The tool aims to keep the output at or below the selected target. The final size may be slightly lower because compression depends on the image content, dimensions and output format.

Why can PNG dimensions become smaller?

PNG uses lossless compression and preserves transparency. To reach a very small target size, the tool may need to reduce the image dimensions.

Will PNG transparency remain intact?

Yes, when PNG is selected as the output format. If you choose JPG, transparent areas are replaced with a white background.

What is the difference between Image Size Reducer and Image Resizer?

Image Size Reducer targets the file size in KB. Image Resizer changes image width and height in pixels. Use Image Resizer when you need specific dimensions.
