What this tool does
Image Resizer changes how many pixels wide and tall your picture is. Enter an exact size, such as 1080 × 1080 for a social post or 600 pixels wide for a form, or scale by a percentage. With “Keep proportions” on, the other side is worked out for you so the picture never looks stretched.
Making an image smaller also makes the file smaller. Making it larger cannot add real detail, so enlarged images can look soft; the tool warns you when you enlarge.
Who it helps
- Students and job seekers whose application asks for a photo of an exact size, such as 600 × 600 pixels.
- Social media and content creators preparing images for posts, thumbnails and banners.
- Website and shop owners making product photos the right width for their pages.
How to use it
- Add an image. Drop it on the box, choose it, or paste it with Ctrl+V.
- Enter the new size. Type a width or height in pixels, or pick a percentage.
- Check and download. The preview and new file size update as you type. Then download the resized image.
Common image sizes
| Use | Size in pixels |
|---|---|
| Square social media post | 1080 × 1080 |
| Portrait social media post | 1080 × 1350 |
| Video thumbnail | 1280 × 720 |
| Full HD wallpaper or slide | 1920 × 1080 |
| Profile photo | 400 × 400 or larger |
Square sizes such as 300 × 300, 600 × 600 or 1080 × 1080 pixels are common examples. If your image isn’t square yet, crop it first with the Image Cropper, then type the size here.
Sizes change over time and differ between websites, so always check the current requirements of the site or form you are using.

Frequently asked questions
How do I resize without stretching the picture?
Leave “Keep proportions” turned on and type only the width or the height. The other side is calculated so the shape stays the same. To get an exact shape such as a square, crop the image first with the Image Cropper.
Will resizing reduce the file size?
Making an image smaller in pixels almost always makes the file smaller. The new file size is shown before you download. For an even smaller file, use the Image Compressor.
Can I make a small image bigger?
Yes, up to 1000%, but the browser can only spread the existing pixels out, so the result will look softer. It cannot invent missing detail.
What does “percent” mean here?
50% makes the width and height half as big. The image then has a quarter of the pixels, so the file is usually much smaller.
Is my image uploaded?
No. Your browser resizes it on your own device. Nothing is sent to Freetol or stored anywhere.
