Resize Image Online FAQs

Is it safe to use this tool for private or copyrighted images?

Yes, it is entirely secure. Because this tool runs completely on client-side code, your images are never uploaded to any server. The entire resizing process happens directly on your machine, ensuring total data privacy.

How does the “Keep aspect ratio” option work?

When this box is checked, you only need to input either the desired width or height. The tool will automatically compute the other dimension based on the image’s original proportions, keeping it from stretching.

Can I resize different image formats together in a batch?

Yes! Our resizer supports a wide range of popular web image formats. You can upload a mixed batch, configure your dimension targets, and resize all of them together into a convenient ZIP archive.

Do I need to pay or sign up to resize large batches of images?

Not at all. This tool is completely free, web-based, and requires no registration or installations. There are no artificial limits on file counts since the processing relies entirely on your local browser’s performance.
