Image Resizer & Compressor

Drop an image onto the upload area or select one from your device. Enter the width or height you need, keep the aspect ratio locked so the picture is not distorted, or apply one of the percentage presets for a quick reduction. A live preview shows the result before you commit to anything.

Choose an output format and use the quality slider to trade file size against detail — JPEG and WebP compress photographs well, while PNG preserves sharp edges and transparency. The size comparison tells you exactly how many kilobytes you saved, and the download button saves the processed file. All resizing happens on a canvas inside your browser, so your photos are never uploaded to any server.
