About Image Resizer

Resize an image to fit a website, presentation, form or social post. Enter the required width and height in pixels, optionally preserve the original aspect ratio, and export a resized image from your browser.

How to use this tool

Choose an image, enter the target width and height, decide whether to preserve its aspect ratio, and select Resize. Enlarging a small image cannot recreate missing detail.

Privacy and file handling

Supported file processing happens locally in your browser. PDF tools load a JavaScript library from a CDN; selected documents are processed in the browser rather than uploaded by this page. An internet connection is required to load the PDF library. Avoid using shared devices for sensitive documents.

Important notes

Different websites have different image requirements. Confirm the required pixel dimensions and file-size limits before uploading.

Frequently asked questions

Is this tool free?

Yes. You can use this tool without creating an account.

Are my files uploaded?

This tool does not intentionally upload selected files to this website. Your browser still loads the page and required scripts over the internet.

Will the output always be smaller or better?

Not always. Results depend on the original file, selected settings and output format. Review the downloaded result before using it.
