How to use this tool
What this tool does and how it can help.
An image resizer adjusts an uploaded image to a target width and height without sending any file to a server. It is useful when you need consistent dimensions for web pages, forms, thumbnails, or social media previews.
For web uploads, resizing before publishing can reduce bandwidth usage, speed up page rendering, and keep layouts looking consistent across devices.
- Upload an image and keep track of its original dimensions.
- Set target width and height, with optional aspect-ratio lock.
- Resize in the browser and preview the result immediately.
- Download as PNG or JPG, depending on your use case.
FAQ
- Does this tool crop my image?
- No. The image is resized directly to the target dimensions without cropping.
- Is my image uploaded to a server?
- No. All processing is done in your browser. The source image never leaves your device.
- What happens if I disable aspect ratio?
- When disabled, width and height are applied independently, so the image can be stretched or compressed.
