Detailed guide

When to use Image Resizer

Use the resizer when the problem is image dimensions rather than file weight. It is useful for profile photos, thumbnails, blog images, product shots, and upload forms with width or height limits.

How the result is produced

The image is decoded in the browser, drawn at the target dimensions, and exported as a new file. Aspect-ratio controls help avoid stretched or squashed output.

Practical example

Resize a 4000 × 3000 camera image to 1200 × 900 before uploading it to a website hero section.

Accuracy and limitations

Image quality depends on the source file and selected settings. Keep the original file when quality is critical.

Frequently asked questions

What happens if I resize a small image larger?

Should I resize or compress first?

Resize first when dimensions are too large, then compress if the file size is still higher than needed.
