Image Compressor to Size — Most image compressors let you pick a quality, but not a target size. This one does the opposite: you pick a size (e.g. 100 KB), and the tool iteratively re-encodes the image at decreasing quality until the result fits.
Your image never leaves the browser. Compression happens locally in JavaScript.
