Image Resizer
Resize JPG, PNG and WebP images to exact dimensions.
Resize Image
Get the exact pixel dimensions you need
A photo straight off a phone is typically four thousand pixels wide and several megabytes in size. Dropped into a blog post or an email signature unchanged, it wastes bandwidth, slows the page down and often breaks the layout. Resizing to the dimensions the design actually calls for is the single easiest performance win available to most sites.
This resizer lets you set exact width and height in pixels, or scale by percentage, with the option to keep the original aspect ratio so nothing ends up stretched. Uploaded files are processed directly on our servers and are not stored once the resized version is generated.
Resizing an image step by step
- Select the image you want to resize, or drag it into the box above.
- Enter the target width, the target height, or a percentage of the original size.
- Leave the aspect-ratio lock on unless you deliberately want to distort the image.
- Apply the resize and check the preview.
- Download the resized file.
What the resizer handles
- Exact pixel dimensions — type the width and height a template or platform requires.
- Percentage scaling — shrink to half or a quarter without working out the arithmetic.
- Aspect-ratio lock — set one dimension and the other follows, so nothing is squashed.
- Common formats — works with JPG, PNG and WebP files.
- Server-side processing — the image is processed on the server and is not retained once resized.
- Smaller files — fewer pixels means a smaller file, which means faster pages.
Sizes worth knowing
- Blog body images rarely need to be wider than 1,200 pixels, even on large screens.
- Open Graph and social preview images are conventionally 1200 × 630 pixels.
- Email signatures and inline email images should stay under about 600 pixels wide.
- Profile avatars are usually square — 400 × 400 is plenty for most platforms.
- Marketplace and e-commerce listings often specify a minimum, commonly 1000 pixels on the long edge.
Resizing questions
Will resizing reduce the image quality?
Making an image smaller is generally safe: you are discarding pixels you did not need. Making it larger is not, because the extra pixels have to be invented, and the result looks soft. Always start from the largest original you have.
What is the difference between resizing and cropping?
Resizing changes the dimensions of the whole image, keeping everything in frame. Cropping cuts away part of the image to change its shape or focus. If you need a square from a rectangle without squashing anyone, crop first, then resize.
Are my images uploaded to your server?
Yes. Your image is uploaded to the server to be resized, but it is not stored once processed. See our privacy policy for details.
Which format should I keep?
Use JPG for photographs, PNG when you need transparency or crisp text and lines, and WebP when you want the smallest file and only need modern browser support.
Does resizing also compress the file?
Reducing dimensions reduces file size substantially on its own, because there is simply less data. If you need to go further, run the resized image through a compressor afterwards.
