Free Online Image Resizer
Need to resize images quickly without installing any software? This free tool lets you change the dimensions of any image directly in your browser. Your files are never uploaded to a server — everything happens locally on your device.
Resize by Pixels or Percentage
Choose By Pixels to set an exact width and height in pixels — perfect for web development, social media posts, or any project that requires specific dimensions. Choose By Percentage to scale images up or down relative to their original size — great for quickly making a batch of images 50% smaller.
Bulk Image Resize
Select multiple images at once and apply the same resize settings to all of them in one click. When you have more than one result, a Download All as ZIP button appears so you can grab everything at once.
Lock Aspect Ratio
When resizing by pixels, enable the aspect ratio lock to automatically calculate the height when you type a width (and vice versa). This prevents your images from looking stretched or squashed.
Output Format & Quality
You can keep the original format, or convert all your resized images to JPEG, PNG, or WebP at the same time. Adjust the quality slider for JPEG and WebP to balance file size against image quality.
