Lossy compression (like JPEG) removes some image data to significantly reduce file size, which might slightly affect quality. Lossless compression (available for PNG) reduces file size without any quality loss by using more efficient encoding.
Yes! Use our 'Batch' mode to drag and drop multiple images. You can apply global settings or adjust them individually, then download all compressed files as a single ZIP.
