Why image size matters for a website
A very large image can slow a page and use more data than the page needs. When you resize an image to the size it will actually be shown at, the page stays clearer and lighter, and the photo still looks right. That is why a simple image resizer online is useful before you upload a photo to a blog, a shop page or a social post.
Resize images for a website or a social post
Use the iWebSeoTool Image Resizer to set the exact size a layout asks for, then download the result and upload it where you need it. If you also need to turn photos into a document, try the PDF Converter, or return to the iWebSeoTool home page to see the other tools on the site.
Frequently asked questions
Yes. Enter the exact width and height you need for the website or social post, keep Keep aspect ratio on if you want the shape to stay the same, choose PNG, JPEG or WebP, and download the resized image. Check the preview and the original dimensions shown first, so you start from the right size and do not enlarge a very small photo too far.
No. The image is resized in your browser and is not uploaded to iwebseotool.com and is not stored by the tool. When you leave the page, the image you chose stays on your own device unless you download the resized copy.
Choose a JPG, PNG, WebP or GIF file, check the preview with its original dimensions and file size, enter the width and height you want, choose PNG, JPEG or WebP for the result, then choose Download Resized Image. The resized image is created in your browser.
Yes. The iWebSeoTool Image Resizer is free to use on iwebseotool.com. You can resize an image online without signing up and without paying, and there is no limit stated on the page for a single quick resize.
Keep aspect ratio is on by default. When it is on, changing the width also changes the height in the same proportion, so the picture does not look stretched or squashed. Turn it off only if you want to set width and height independently.
You can choose a JPG, PNG, WebP or GIF file to resize. For the resized result, you choose PNG, JPEG or WebP, then download it with Download Resized Image. So you can, for example, resize a JPG and save the smaller version as a PNG.
Making an image smaller usually keeps it looking sharp, but it cannot add detail that was not there before. Making a small image much larger can make it look soft or blurry. Choosing a different output format, such as JPEG instead of PNG, can also change file size and sharpness, so check the downloaded result before you use it.
