About this image resizer

Resizing and compressing are two different jobs, and forms usually need both. Compressing re-encodes an image at lower quality; resizing changes how many pixels it has. If a portal asks for a 200 × 230 photograph, or caps the upload at 50 KB, this is the tool for it.

Everything runs in your browser on a canvas element. Nothing is uploaded, there is no daily limit, and the original file on your device is never modified.

There are three ways to work. Pixels lets you type an exact width and height, with an aspect-ratio lock so the picture does not come out stretched. Percent scales the whole image by a factor, which is the quickest way to halve a photo. Target KB is the one most people want: give it a size and it lowers the quality until the file fits, then reduces the dimensions as well if quality alone cannot get there.

You can also change format on the way out. JPG reaches small targets most reliably because it is lossy. PNG is lossless and keeps transparency, so it will not hit very small sizes but it keeps sharp edges clean. WebP usually lands somewhere between the two.

How to use it

  1. Add an image

    Drop in a JPG, PNG, WebP or AVIF file. Its current dimensions and size are shown straight away.

  2. Choose how to resize

    Type exact pixels, drag the percentage slider, or enter a target size in KB and let the tool work backwards to it.

  3. Check and download

    The result appears beside the original with its new dimensions and file size, so you can adjust and try again before downloading.

Questions about this tool

How do I resize a photo to 20 KB for an application form?

Switch to Target KB, type 20, and pick JPG as the output. If the result comes back larger than asked, the image likely has a lot of detail — crop it to just the required area first, which removes pixels the resizer would otherwise have to keep.

How do I resize to an exact size like 200 x 230 pixels?

Use Pixels mode and turn the aspect-ratio lock off, then enter both numbers. With the lock off the image is stretched to fit exactly, so crop to roughly the right proportions first if that matters.

Will resizing make the image blurry?

Making an image smaller is generally safe. Making it larger cannot invent detail that is not there, so anything scaled well above 100% will look soft. Resize down from the largest original you have rather than up from a small copy.
