About Bulk Image Resizer
A free online image resizer for batch resizing photos — fast, private, and entirely browser-based.
Why We Built This
Most online image resizers require you to upload your files to a remote server. That means your images travel across the internet, sit on someone else's infrastructure, and may be stored or processed in ways you can't verify.
We built Bulk Image Resizer to solve that problem. Every image you process stays on your device. The resizing happens right inside your web browser using the native Canvas API — no server, no uploads, no middleman.
How It Works
100% Client-Side
Your images are processed using the browser's built-in Canvas API and Web Workers. Nothing leaves your device.
Batch Processing
Upload dozens or hundreds of images, set your target dimensions, and resize them all in one pass.
No Account Required
No sign-ups, no emails, no paywalls. Open the page and start resizing immediately.
Open Technology
Built with Next.js, TypeScript, and Tailwind CSS. Hosted on Vercel's global CDN for fast access worldwide.
What You Can Do
- Resize by exact pixel dimensions (width × height)
- Scale by percentage (50%, 75%, or any custom value)
- Constrain to a longest edge (e.g., max 1200px)
- Convert between JPEG, PNG, and WebP formats
- Adjust output quality with a simple slider
- Download all processed images as a single ZIP file
