Image Resizer
What the Image Resizer does
The Image Resizer changes an image's pixel dimensions to an exact width and height you specify, with an option to lock the aspect ratio so the image doesn't distort.
How to use it
- Choose an image file.
- Enter the target width and height in pixels.
- Click Resize Image and download the result.
Common uses
- Resizing a photo to meet a specific upload requirement (profile picture, banner, thumbnail).
- Shrinking an oversized image before adding it to a webpage or document.
- Preparing images at consistent dimensions for a gallery or product grid.
- Resizing an image to fit a specific print or design template.
- Scaling down a high-resolution photo for faster web loading.
Good to know
Locking the aspect ratio when resizing prevents the image from looking stretched or squashed — if you need an image to fit an exact width and height that doesn't match its original proportions, consider cropping instead of forcing a resize, since forced non-proportional resizing usually looks noticeably distorted.
Resizing an image up (making it larger than its original dimensions) doesn't add real detail that wasn't there — the software has to invent new pixel values through interpolation, which is why enlarged images typically look softer or blurrier than the original, unlike shrinking an image down, which generally preserves apparent sharpness well since it's discarding detail rather than inventing it.
Frequently asked questions
With aspect ratio locked, changing the width automatically recalculates the height (and vice versa) to prevent your image from looking stretched or squashed.
Resizing to smaller dimensions typically reduces file size since there are fewer pixels to store, but for maximum compression also try the Image Compressor.
