About image resizing
Resizing an image means changing its width and height in pixels. This is useful for adapting photos for websites, social media, forms, documents, presentations and other online uses.
When should I resize an image?
You can resize an image when it is too large to upload, when you need to adjust its visual size or when you want to make it more suitable for a web page.
Is keeping the aspect ratio important?
Yes. Keeping the aspect ratio prevents the image from looking stretched or distorted. That is why the option to keep proportions is enabled by default.
How does this tool work?
The image is loaded in your browser, resized using JavaScript and made available for download. No file needs to be uploaded to a server.
