Resize image
Scale an image to the dimensions you need.
Resize image scales an image to an exact width and/or height in pixels, with an optional aspect-ratio lock so you don't accidentally stretch or squash the result.

One image at a time
How to use
- Upload one image.
- Enter the width and/or height you want — leave "Lock aspect ratio" on to avoid stretching.
- Click "Resize & download".
Common use scenarios
- Resizing a photo to fit a website's or app's required image dimensions.
- Shrinking a large camera photo down to a reasonable size for web use.
- Producing a specific thumbnail size for a product listing or profile photo.
- Standardizing a batch of differently-sized images to one consistent dimension.

How we verify Resize image
How to confirm the resized image comes out at the right dimensions, undistorted.
Locked vs. unlocked aspect ratio
With "Lock aspect ratio" on, entering just a width automatically calculates a proportional height (and vice versa) — turning it off lets you set both independently, which can stretch or squash the image if the numbers don't match the original proportions.
Enlarging vs. shrinking
Shrinking an image (making it smaller than the original) generally looks fine. Enlarging it beyond its original dimensions doesn't add real detail — it just stretches existing pixels, which looks blurrier the more you enlarge.
Confirming the final pixel dimensions
After downloading, check the resulting image's actual dimensions (most operating systems show this in file properties or a quick look preview) to confirm it matches what you entered.
Before you rely on the result
- You've decided whether the aspect ratio should stay locked for this image.
- The width/height values you entered make sense relative to the original image size.
- You're not enlarging a small image far beyond its original size, if sharpness matters.
- You've checked the downloaded file's actual pixel dimensions match what you intended.
Who this is for
- Anyone who needs an image at an exact pixel size for a website, app, or form.
- Online sellers producing consistently-sized thumbnails across a product catalog.
- Anyone shrinking oversized camera or phone photos down for practical web use.
- People standardizing a batch of images to the same dimensions before using them together.
Real-world examples
Meeting a platform's required image size
A user needs to upload a profile photo that must be exactly 400×400 pixels; they resize their photo to that exact dimension before uploading.
Shrinking a huge camera photo for the web
A photographer's camera produces 6000×4000 pixel images; they resize a photo down to 1200×800 for a web gallery so it loads quickly without unnecessary detail.
Standardizing product thumbnails
An online seller resizes a batch of differently-sized supplier photos to a consistent 800×800 square so their storefront looks uniform.
Limitations
- Enlarging an image beyond its original size will make it blurrier, not sharper.
Frequently asked questions
What happens if I turn off "Lock aspect ratio"?
You can set width and height completely independently — useful for an exact target size, but if the ratio doesn't match the original image, the result will look stretched or squashed.
Can I make an image bigger than its original size?
Yes, but enlarging doesn't add real detail — it stretches the existing pixels, so the result gets progressively blurrier the more you enlarge it beyond the original size.
Does resizing affect the image's format or quality settings?
No — resizing only changes the pixel dimensions; the output format follows your source image's format and doesn't apply any additional compression on its own.
Can I resize by percentage instead of exact pixels?
The tool currently takes exact width/height values in pixels — to resize by a percentage, calculate the target pixel dimensions yourself (e.g., 50% of a 2000px-wide image is 1000px) and enter those.
