Resize image online means people want a tab, not a desktop installer. The job is still pixels or percent: 800×600, 50%, lock ratio.

IMG4FIX runs that job on a canvas in this browser. “Online” here is the delivery (a URL), not an upload to a farm.

If you needed 20 KB rather than 800 px, you wanted a cap page. Online resize does not guess kilobytes.

What you can set

Width and height in pixels, or a percentage of the original. Lock ratio so faces do not squash. One empty dimension is computed from the original aspect.

How to resize an image online here

Drop a file or paste from the clipboard. Choose pixels or percent. Run. Download. A batch uses the same numbers on every file.

Why local still counts as online

You opened a website. That is online. The pixels never have to leave the device for this encode. That is the privacy difference versus classic converters.

Frequently asked questions

Do I need to install software to resize online?

No. This page is the online tool. After the scripts load, encode can run even if the network drops.

Is online resize uploading my photo?

IMG4FIX does not. Some other “online” tools do. If the preview appears without a progress bar to a remote server, you are local.

Online vs Resize Image hub?

Same engine. This H1 matches “resize image online.” The listed hub is Resize Image.

Can I upscale online?

You can type a larger width. For a dedicated 2× pass with enlarge copy, use Increase Image Size.

Mobile?

Yes. The layout is built for phones. Large files may be slower on old devices.
