Browser-based resizing is practical for everyday image prep

Image resizing is useful for uploads, content publishing, CMS prep, emails, and screenshots that need to fit a specific layout or file target.

This tool keeps the process simple with dimension inputs, aspect-ratio locking, and downloadable output without sending the image anywhere.

Helpful tips for a better result
  • Keep aspect ratio locked unless you intentionally want to stretch the image.
  • Resize before converting to Base64 if you want a shorter output string.
  • Choose an output format that matches your use case before downloading.
Frequently asked questions
Can I keep the original aspect ratio?

Yes. The resizer includes an option to keep width and height proportional while you edit one side.

What output formats can I use?

The page supports practical browser-friendly output formats such as PNG, JPEG, and WebP when the browser allows it.

Does the resizing happen locally?

Yes. The image is resized in your browser using built-in browser APIs.
