Image Compression Previewer
Load a photo or screenshot and watch the compressed result next to the original as you move the quality slider. The browser re-encodes the canvas to WebP, JPEG or PNG and reports both file sizes and the saving, so you can judge whether artifacts are acceptable before replacing an asset. The file never leaves this tab.
