Frequently Asked Questions

Is Social Media Image Resizer free?

Yes. Social Media Image Resizer runs in your browser and is free to use, with no account, no watermark, and no usage cap.

Do I need to create an account?

No. Open the page and use it. An account only becomes useful if you want to save tools to your own toolbox.

What happens to my data?

Social Media Image Resizer does its work on your own device. Your input is never uploaded to us, which is why it also works with sensitive material.

Is there a file size limit?

Because the work happens on your own device, the practical limit is your device's memory rather than an upload cap. Large files are fine on a desktop browser.

Do I need to install anything?

No. Social Media Image Resizer runs in the browser on desktop, tablet, and phone. There is nothing to download and nothing to keep updated.
