Resize one image for practical layouts
These real outputs were made from the same 1536 × 1024 source through this Resize Image tool. Exact dimensions are useful when a website or form gives you a pixel requirement.

Keep proportions or set exact pixels
Use the ratio lock for ordinary resizing. Turn it off only when the destination requires a particular width and height.
Keep aspect ratio
Changing one dimension updates the other to preserve the image shape.
Use it for photos, website images, and any destination that accepts the original ratio.
This avoids a stretched or squashed result.
Set exact dimensions
Use it when an upload form specifies both a width and height.
An image with a different shape can look stretched when forced into exact dimensions.
Use Crop Image first when you need a different shape without distortion.
Start with the destination requirement
There is no universal best image size. Use the dimensions requested by the place where the image will appear.
Profile and product images
Check whether the destination requires a square or a specific pixel size.
Website content
Keep the original ratio unless the page layout calls for a different crop.
Smaller file needs
Resize first, then use Image Compressor when file size also matters.
FAQ
You can increase the pixel dimensions, but ordinary resizing cannot create detail that is not in the source. A large enlargement may look soft or pixelated; this is not an AI upscaler.
No. Resizing changes the pixel width and height, while compression mainly changes how the image data is encoded. The file size may change after resizing, but this tool cannot guarantee a target KB.
You can resize up to 20 static JPG, PNG, WebP, or AVIF images at once, with a 50 MB limit per file. Each result keeps its input format and is downloaded separately; animated images and ZIP download are not supported.
No. This image tool runs in your browser, so your files stay on your device while they are processed.
No. Keeping the aspect ratio changes both dimensions together. If you unlock it, the image is resized to the exact width and height and may look stretched.
Use the dimensions given by the website, form, or app where the image will appear. Keep the aspect ratio locked when there is no exact requirement.
Keep the aspect ratio locked and change only the width or height. If the destination needs a different shape, crop the image to that ratio before resizing; entering both dimensions with the lock off can stretch the image.
