Resize Images Online Free
Resize any image to exact dimensions or target file size. I use this for government forms that say "photo must be under 100KB" — just drop, set the size, done.

Common Questions
📏 What's the difference between resizing by pixels and KB?
Pixels is the actual dimensions (width × height). KB is the file size. For example, a passport photo might need to be exactly 50KB — you want our resizer. For Instagram, you want 1080×1080 pixels.
📱 Does this work on mobile?
Yes, tested on my own phone. The buttons are big enough to tap. Resize photos directly from your phone gallery before uploading anywhere.
🔒 Are my images uploaded anywhere?
Nope. Everything stays on your device. The resizing happens right here in your browser. I never see your images.
🖼️ What image formats work?
JPG, PNG, and WebP all work fine. Drop any of these and resize away.
