A PRACTICAL GUIDE

Resize pixels without stretching your photo

An image resizer changes the number of pixels in a picture. Use it when a website needs a narrower image, an avatar needs smaller dimensions, or a photo is too large for your layout. Changing pixel dimensions is different from setting a file-size limit in KB.

Choose a photo

Open a JPG, PNG or WebP. Width and height start at the original pixel dimensions.

Set the width or height

Keep the aspect ratio locked and change one side. For a 1536 × 1024 photo, setting width to 600 gives a 600 × 400 result. Unlocking the ratio can stretch faces and objects.

Choose a format and save

Download PNG, JPG or WebP. Choose “Use result” if you want to add text, split the smaller photo or compress it next.

When to use this tool

For a website image, reduce the width while keeping its proportions. For a square avatar, crop to a square first, then resize. Enlarging a small photo adds pixels by interpolation; it does not recover missing detail or perform AI enhancement.

Questions about resize image

Does resizing also compress the file?

Fewer pixels often produce a smaller file, but pixel dimensions do not guarantee a specific KB size. The output format and encoding quality matter too. Use the compressor if file size is your main constraint.

Can I resize without cropping?

Yes. Leave the aspect ratio locked and change one dimension. All of the original composition remains visible.

Why is the other dimension changing?

The aspect-ratio lock calculates the other side so your picture keeps its shape. Unlock it only when you intentionally want independent dimensions.
