Output format

Automatic compression with visual quality checks. PNG can combine similar colors; JPEG and WebP use adaptive quality. Dimensions and transparency stay unchanged. Compare the previews at 100%.

If the selected format fails the quality check, a lossless PNG is offered instead. Compare the preview before using the result.

Output

How it works

Choose or drop an image and select the output format. Run the tool to check quality and size, inspect both previews at 100% and download the result.

Frequently asked questions

Why is the compressed image sometimes no smaller?

An image may already be well optimized. The tool checks quality before accepting a smaller result and can offer PNG when a lossy format does not pass that check. Compare the displayed file sizes and the previews at 100%; a different format does not always mean a smaller file.
