Quickly resize dozens of images to identical dimensions. Choose a target width and height, or scale by a percentage, while optionally locking the original aspect ratio to avoid distortion. Once processed, all resized images are bundled into a single ZIP file for instant download—perfect for preparing photos for web, email, or social media in one go.
Yes—each image is resized and saved in the format you choose from the output format dropdown.
When scaling by percentage, both dimensions are multiplied by the same factor, so the aspect ratio is preserved automatically. The lock is only relevant when you enter explicit pixel values.
No. All resizing happens in your browser. Your files stay completely private.
