How it works

ConvertCabin does this on a canvas inside your browser tab — your image is processed on your device and never uploaded. There's no queue, no daily cap and no account.

Because the work happens locally it stays free, unlimited and private, and keeps working offline once the page has loaded.

About resizing

Enter a width and the height follows automatically with the aspect ratio locked, or unlock it to set both. Resizing happens on a canvas in your browser, so your image never leaves your device.

Tips & common uses

Resizing changes an image's pixel dimensions — making it smaller to save space or fit a limit, or scaling it to an exact width and height.

  • Meeting upload limits for forms, marketplaces, or profile pictures that cap dimensions.
  • Speeding up web pages by shrinking oversized photos to the size they're actually displayed.
  • Fitting a template that needs an exact pixel width and height.
  • Reducing file size for email when the full-resolution image is unnecessarily large.

Frequently asked questions

How do I resize an image?
Drop your images, set a width (height follows automatically), and download the resized versions.
Can I set both width and height?
Yes. Untick Lock aspect ratio to enter an exact width and height.
Are my images uploaded?
No. Resizing happens on your device.
Will making an image larger improve its quality?
No. Enlarging stretches existing pixels and can look soft — you can't add detail that isn't there. Resizing down is lossless in perceived quality.
Does resizing keep the aspect ratio?
Keep width and height proportional to avoid stretching; change only one and let the other scale to match for a natural look.
