Frequently Asked Questions about Image Resizer

Will resizing reduce the clarity of my photo?

Downscaling an image to smaller pixel dimensions preserves sharp clarity. Upscaling beyond the original dimensions may cause pixelation because the original file does not contain extra pixels.

Can I resize images for social media profile pictures?

Yes. You can enter standard social media dimensions such as 1080x1080 (Instagram square), 1200x630 (Facebook/Twitter OpenGraph), or 400x400 (avatar).

Are my images stored on ToolsCluster servers?

No. The image resizing executes entirely inside your browser memory using the HTML5 Canvas API.
