Resize images by exact pixels, percentage scale, or fit within a bounding box.
Lock aspect ratio, choose output format and quality, batch process multiple files
— everything runs locally in your browser.
Exact: Set a specific width and/or height. With aspect ratio locked, the missing dimension is calculated automatically.
Scale %: Multiply original dimensions by a percentage. 50% halves the image; 200% doubles it.
Fit box: Downscale (or upscale) the image to fit within a maximum width and height while preserving proportions — same as CSS object-fit: contain.
How To Use
Drop or browse up to 20 image files.
Choose a resize mode and enter your target dimensions.
Select output format (PNG preserves transparency; WebP is smallest).
Click Resize Images and download individually or all at once.
