Image Resizer | Resize Photos by Width and Height
Resize images by pixel width and height, keep aspect ratio when needed, and export a smaller version for websites, profiles, or forms.
Resize Images to Exact Pixel Dimensions
Set a target width and height for photos, profile pictures, product images, documents, or web graphics while keeping the aspect ratio when it matters.
Avoid Stretching or Cropping by Accident
Use aspect-ratio lock for natural resizing. If a platform requires exact dimensions, check the preview so faces, logos, and important details are not distorted.
Common Image Resize Use Cases
Resize images for website uploads, avatars, ecommerce listings, blog thumbnails, email attachments, admin panels, and forms that reject oversized dimensions.
About This Tool
Image Resizer changes the pixel dimensions of an image to a target width, height, or both while optionally maintaining the original aspect ratio. It is used to prepare images for specific upload requirements, profile pictures, banners, and print dimensions.
When to Use It
Use this when a platform requires a specific image dimension such as 1080x1080 pixels for Instagram, when resizing a batch of photos to a consistent width before uploading them to a gallery, or when reducing very large images to a web-friendly size.
How to Use
- Upload your image file.
- Enter the target width, height, or both in pixels.
- Choose whether to maintain the aspect ratio.
- Select the output format.
- Download the resized image.
Frequently Asked Questions
What happens if I only set the width?
If only width is set and aspect ratio is locked, the height is calculated automatically to keep the image proportional.
Can I make an image larger with this tool?
Yes, but scaling an image larger than its original dimensions reduces sharpness. Always resize down from a high-resolution source when possible.
What file formats can I resize?
The tool supports JPG, PNG, WebP, and GIF input files. The output format can be set independently.
