Image Resizer is an online tool that allows you to freely change image dimensions. It supports precise pixel-based sizing, percentage-based scaling, and preset sizes for social media platforms. The aspect ratio preservation option ensures images are resized without distortion. All processing is done in your browser, so your images are never sent to a server.
Aspect ratio is the width-to-height proportion of an image. When this option is enabled, changing the width automatically adjusts the height (or vice versa), preventing the image from being stretched or squashed.
Yes, enlarging beyond the original size may degrade quality as pixels are interpolated. For high-quality enlargements, we recommend using high-resolution source images.
Presets are fixed, but you can manually edit the width and height values after selecting a preset. You can also select 'Custom' to freely specify any size.
Generally, shrinking an image also reduces file size. However, results vary depending on format and content. Check the file size in the preview before downloading.
GIF format is supported, but resizing an animated GIF will output it as a static image (first frame only). For resizing while preserving animation, please use a dedicated tool.
