PNG uses lossless encoding; the quality slider has no effect. JPEG transparency is replaced by white. Metadata is not retained.
How to use this tool
Drop an image, select the output format and quality, then compress. Compare the before and after sizes before downloading.
What to know
PNG is lossless, so the quality slider does not affect it. A conversion can increase file size; the actual difference is always shown.
