What is this tool?
Bulk Image Resizer changes each image's pixel dimensions using your browser's built-in canvas engine. In percentage mode every image is scaled by the same factor from its own size; in exact-dimensions mode you set a fixed width and height, with an optional aspect-ratio lock so images aren't stretched. Everything happens on your device — images are never uploaded to a server.
Common uses
- Resizing a batch of product photos to the same scale before uploading
- Hitting exact dimensions required by a website or form
- Preparing images for social media size requirements
- Shrinking a set of oversized photos before sharing

FAQ
Is my image uploaded anywhere?
No. The resizing happens entirely in your browser using canvas rendering — images never leave your device.
Can I resize more than one image at once?
Yes, add as many images as you like and they're all resized with the same settings — download them individually or all as a ZIP.
What's the difference between percentage and exact dimensions?
Percentage scales every image by the same factor from its own original size; exact dimensions sets a fixed width and height for all of them, with an optional aspect-ratio lock.
