What is an Image Resizer?
An image resizer changes the dimensions (width and height) of an image. It's useful for reducing file size, fitting images into specific layouts, or preparing photos for social media and websites.
How to use this tool
- Drag and drop your image, or click to browse.
- Enter the new width and height (or keep aspect ratio).
- Choose the output format (JPEG, PNG, or WebP).
- Adjust quality if exporting JPEG or WebP.
- Click Resize Image and download the result.
Which format should I choose?
- JPEG: Best for photos, small file size, lossy compression.
- PNG: Best for graphics with transparency, larger file size.
- WebP: Modern format, excellent compression and quality.

Frequently Asked Questions
Is this Image Resizer free?
Yes, completely free. No signup, no watermarks, no limits.
Are my images uploaded to a server?
No. Images are processed entirely in your browser using the Canvas API. Your files never leave your device.
What image formats are supported?
You can upload JPG, PNG, WebP, GIF, and BMP. You can export as JPEG, PNG, or WebP.
Does resizing reduce image quality?
Downscaling with high-quality smoothing preserves quality well. For JPEG and WebP, you can control the quality slider to balance size and quality.
What does 'maintain aspect ratio' do?
When enabled, the image keeps its original proportions — if you change width, height adjusts automatically to match.
