Image Resizer
Image ToolsResize images by dimensions or percentage.
Resizing an image changes its pixel dimensions to fit a specific width, height, or scale while keeping the file lightweight. This tool lets you resize by exact dimensions (with an optional aspect-ratio lock so the image never distorts) or by a percentage of the original size. Resizing happens entirely in your browser — your image is never uploaded, so it stays private. Smaller dimensions mean a smaller file, ideal for emails, websites, and thumbnails; larger dimensions enlarge the image but cannot add detail that was not in the original.
