A PRACTICAL EXAMPLE
Know what a useful result looks like.
Add breathing room without cropping your source pixels.
Check before using the result
- Check the new dimensions.
- Choose PNG when transparent padding is required.
When the result needs work
Adding a border increases dimensions and can increase file size. It does not shrink the original image to fit an upload limit.

GOOD TO KNOW
A few useful answers.
Does adding a border crop the image?
No. The border is added outside the original image. A 20-pixel border increases both the width and height by 40 pixels. Your original pixels remain in the center.
Can I add transparent space instead?
Yes. Choose transparent padding and download the PNG. Transparent areas appear as a checkerboard in the preview and can show the background of the page where you use the image.
Are my images uploaded or stored?
No. These tools read and process image files locally in your browser. No account is required, and this workspace does not send filenames or editing results to our server.
Which images can I use?
Use JPG, PNG or WebP files up to 50 MB each, 8,192 pixels on either side and 32 megapixels in total. Animated files are processed as a still frame. For HEIC, use our HEIC to JPG converter first.
