Things to know
PNG images with transparency compress differently than JPGs (PNG is lossless by nature, so size reduction is more limited compared to JPG's adjustable lossy compression). For maximum size reduction of a photo where transparency isn't needed, converting to JPG first (see Image Converter) often gives smaller files.
How your data is handled
Compression happens entirely in your browser via the Canvas API — your image is never uploaded.
