About the image resize tool
This image resize tool lets you change image dimensions for websites, documents, social media, profile photos, thumbnails, and product listings. You can resize by exact width and height, by width only, by height only, or by percentage depending on the result you need.
Resizing is different from compression: resizing changes the pixel dimensions of an image, while compression mainly reduces file size. For best results on the web, resize overly large images first and then compress them if you also need a smaller file.
How to use this tool
- 1. Click the upload area or drag and drop your image file.
- 2. Adjust the settings according to your needs (e.g., format, size, compression level).
- 3. Click the process button and download your optimized image instantly.
Practical tips
Check the final image before publishing it. For website use, aim for the smallest file that still looks clear on the screen size where it will be displayed. For logos, screenshots, and UI graphics, use a format that preserves sharp edges. For photographs, use a format that provides good compression and broad compatibility.
