About this Tool
Get your images to the perfect size. Our Image Resizer lets you quickly resize any image by specifying exact pixel dimensions or a percentage. You can choose to preserve the aspect ratio to avoid distortion and even adjust the output quality to balance file size and appearance. It's the perfect tool for preparing images for your website, social media, or email. The entire process is fast, free, and done securely in your browser.
This tool uses the HTML5 Canvas to create a new image with your specified dimensions. It draws your original image into this new canvas, effectively resizing it. You can then control the quality setting when the new image is exported as a JPEG.

- Adjust the settings (e.g., enter the new width or select a percentage).

Image resizing (or 'resampling') is the process of creating a new version of an image with different dimensions. This tool uses interpolation algorithms built into the browser to ensure the resized image looks as smooth and clear as possible.
What image formats are supported?
The tool accepts all common image formats (like PNG, JPEG, GIF), but the output will always be in JPEG format.
What does 'quality' do?
The quality setting applies to JPEG compression. A lower quality will result in a smaller file size but may introduce visual artifacts. A higher quality will look better but have a larger file size.
What's the maximum image size?
For best performance, it's recommended to use images under 50MB. The tool can create images up to 4000x4000 pixels.
All image processing happens locally in your browser. No files are uploaded to our servers.
