How to use this tool
Are images uploaded?
No. The browser decodes and exports each image locally.
Will every image become smaller?
No. An already optimized image may become larger. Compare the displayed sizes before downloading.
What happens to transparency?
WebP can preserve transparency. JPEG replaces transparent areas with white.
Does this preserve all metadata and animation?
No. The exported image is a still image. Browser re-encoding does not preserve all original metadata.
