Bulk Image Resize
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.

- 3Click Resize & Download ZIP and wait a moment while the tool processes each image in your browser. Your ZIP will download automatically.

Frequently Asked Questions
Can I mix different image formats (PNG, JPEG, WebP) in the same batch?
Yes—each image is resized and saved in the format you choose from the output format dropdown.
Why does the lock‑aspect‑ratio option not work with percentage resizing?
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.
Are my images ever uploaded to a server?
No. All resizing happens in your browser. Your files stay completely private.
