Image Resizer

The Image Resizer is a simple yet powerful tool to adjust the dimensions of your photos and graphics directly in your browser.

Why resize images?

Faster Loading: Smaller images load faster, improving your website's SEO and user experience.
Social Media: Fit your images perfectly into Instagram, Twitter, or Facebook post dimensions.
Email Attachments: Reduce file size to meet email attachment limits.

Features

Aspect Ratio Lock: Automatically calculates the height when you change the width (and vice versa) to prevent your image from looking stretched or squashed.
Quality Control: Adjust the compression level for JPEG and WebP formats to balance between image quality and file size.
Privacy Focused: Your images are processed locally on your device using the HTML5 Canvas API. They are never uploaded to our servers.
