Image Resizer

Resize your image to the exact width and height (in pixels) you specify.

When should you use this?

Use this when you need to fit an image to the exact pixel dimensions a platform requires (a website, social media, an e-commerce product photo).

When shouldn't you use this?

If you're trying to enlarge an image far beyond its original size, the result comes out blurry without AI upscaling; this tool is reliable for shrinking, not blowing up.

Step-by-step

Choose your file in the "Image" field and check its current width and height in any image viewer.
Decide on the target size. To keep the proportions, work out the new height as: old height times new width, divided by old width.
Enter the numbers in "Width (px)" and "Height (px)".
Click "Resize and download". The resized file downloads automatically.

Example

You're adding a 4000 x 3000 phone photo to a blog post, and your content column is 1200 pixels wide. Shrinking the photo to that width keeps the page from loading far more image than it can show. To keep the proportions, calculate 3000 times 1200 divided by 4000, which gives 900. Enter 1200 for width and 900 for height and the photo gets smaller without being squashed or stretched. If a social platform wants a square image, crop to a square first and then resize, rather than forcing a new ratio.

When resizing images

Changing an image's pixel size directly affects its file size and how it looks on screen. Reducing size usually preserves quality; enlarging cannot invent missing detail and the image gets blurry. Keeping the aspect ratio prevents stretching.

Resizing tips

For the web, set the image to the largest width it will be used at; an oversized image slows the page.
Resize keeping the aspect ratio; use cropping if you want a different ratio.
Instead of enlarging a small image, work from the original high-resolution file if you can.
For print, think about pixel size together with the resolution (DPI) for the intended print size.

Things to keep in mind

If you type width and height independently, the image can stretch in one direction. When a round logo turns into an oval, recheck the ratio.
For sharp results on high-density screens, a common practice is to prepare the image at about twice the width it will be displayed at.
Resizing also cuts file size. If it's still too heavy, follow up with the image compressor.
Keep the full-resolution original. If you need a bigger version later, scaling the small copy back up won't look good.

Frequently asked questions

Is my image uploaded anywhere?

No, processing happens entirely in your browser via the Canvas API — your image never leaves your device.

Will there be quality loss?

Some quality loss during format conversion or compression is normal, more noticeable with lossy formats like JPG.

Which formats are supported?

JPG, PNG, and WebP formats are supported.
