Image Resizer is now live on Tools.Town — a browser-based tool to resize images to exact pixel dimensions or a percentage of their current size, with aspect ratio lock and instant download — no software, no server upload.
Prepare images for social media, optimize thumbnails, or scale assets to fit a design spec in seconds.
What Does It Do?
Pixel Resize
Enter exact width and height in pixels. Aspect ratio lock keeps proportions intact automatically.
Percentage Scale
Scale to 25%, 50%, 75%, or any custom percentage — great for making a proportional copy.
Output Format
Download as JPEG, PNG, or WebP regardless of the input format. Control quality for JPEG output.
All resizing is done in your browser. No images are uploaded to any server at any point.
How It Works
Upload image
Drag and drop or select your image. The current dimensions and file size are shown.
Set new size
Enter pixel dimensions or a percentage. Toggle aspect ratio lock to prevent distortion.
Download
Click Resize & Download to save the resized image in your chosen output format.
Why We Built It
Images come in all shapes and sizes, and practically every platform has specific dimension requirements. Resizing shouldn’t require opening an image editor. Image Resizer handles the most common resize operations directly in the browser — in seconds, with no distortion risk as long as aspect ratio lock is on.
