About Resize Image

Need a profile picture at exactly 400×400? A thumbnail for a marketplace? A screenshot scaled down for a README? Enter the dimensions, upload the image, and it's done. If you only set a width or only a height, the aspect ratio is preserved automatically so your photos never come out squished. You can also swap the output format in the same step — resize a large PNG and save it as a smaller JPG, for example. Batch mode handles up to 20 images at once, all delivered in a ZIP. Your files are deleted the moment the download is ready.

How it works

1

Upload your images

Drop in the JPG, PNG, WebP, or HEIC files you want to resize.

2

Enter the new size

Set a width, a height, or both — entering just one keeps the aspect ratio automatically.

3

Download

Grab your resized images instantly — in a ZIP for multiple files.

Frequently asked questions

Will my image look stretched?

No. Enter just one dimension and the other is calculated automatically to keep the proportions. Only if you set both will the image be forced to those exact dimensions.

Which image formats are supported?

JPG, PNG, WebP, and HEIC as input; JPG, PNG, or WebP as output.

Can I resize multiple images at once?

Yes — upload up to 20 images and they're all resized to the same dimensions, delivered in a ZIP.

Is there quality loss when resizing?

Downscaling uses high-quality resampling and looks visually identical. Upscaling a small image can look soft — that's a natural limitation of any resizer.
