Image Compressor
Make image files smaller so they load faster and fit under upload limits, without sending them to any server. Load a photo, drag the quality slider to balance size against sharpness, and the tool re-encodes it in your browser and shows you the original size next to the new size along with the percentage saved. Lowering the quality a little often cuts the file size dramatically while looking almost identical, which is exactly what you want for web pages, email attachments, or forms with a size cap. When the result looks good and the numbers are where you want them, download the compressed copy. Everything happens locally on a canvas, so your photos stay private and the whole thing is fast. Experiment freely, your original file is never modified.
