What is Resize Image?
Whether you need a 600×600 profile picture, a passport-size photo or a banner at exact dimensions, this free image resizer scales any picture to the pixel size you specify. Lock the aspect ratio to avoid stretching, or unlock it for precise control.
How to use Resize Image
- Select the image you want to resize.
- The original dimensions appear below the file — use them as your reference.
- Type your target width or height in pixels.
- Keep “Lock aspect ratio” ticked so the other dimension updates automatically and the image is not distorted.
- Click “Resize & download” to save the new image.
Why use this tool?
Meet exact upload specifications
Application forms, marketplaces and social platforms frequently demand precise pixel dimensions. Typing the numbers is faster and more reliable than dragging handles in an editor.
No distortion
Aspect-ratio lock keeps proportions correct, so faces and logos never end up squashed or stretched.
Frequently asked questions
Does resizing reduce file size too?
Yes — fewer pixels almost always means a smaller file. If you need to hit a specific file size, run the result through the Compress Image tool afterwards.
Can I enlarge a small image?
You can, but enlarging cannot invent detail that was never captured, so the result will look softer. Scaling up beyond about 200% is rarely worth it.
Are my files uploaded to a server?
No. Every tool on Toolraq runs entirely inside your browser using JavaScript and WebAssembly. Your file never leaves your device — there is no upload endpoint at all. You can verify this yourself by opening your browser’s DevTools Network tab while you use the tool.
