What is the difference between increasing KB and increasing pixels?

Increasing KB adds safe, non-rendering comment padding to the file container so server upload validators accept the file weight while keeping the original pixels 100% untouched. Increasing pixels physically expands the width and height on canvas, which should only be done if your form requires larger physical dimensions.

Frequently asked questions

If your portal specifically complains about kilobyte or megabyte limits (e.g. "File size must be between 20 KB and 50 KB"), use our Increase Image Size in KB tool. If it rejects your file for dimensions (e.g. "Width must be 350 px"), use Increase Image Size in Pixels.
