About Changing Size of Image Online

To change size of image files for portals, thumbnails, or print, you need precise width and height — not guesswork in a desktop app. This landing page uses the identical VSPic resize engine as /resize-image.

Switch between pixel entry and percentage sliders, lock aspect ratio when needed, and download when the new dimensions match your requirements.

Frequently asked questions

Can I change size without distorting people?

Turn on Maintain Aspect Ratio so faces and objects keep natural proportions.

What if I only know a percentage?

Use By Percentage mode — 50% halves both width and height.

Will changing size reduce KB?

Often yes when downsizing. For smaller files without dimension change, use Compress Image.

Can I change size of PNG with transparency?

Yes where PNG is supported as output for your source.

Is signup required?

No account is needed.
