Both tools are in Studio under Edit, in the image viewer in Assets, and remove background is also in the Designer.
Remove background (1 credit)
Cuts out the subject and saves it as a PNG with a transparent background. Use it for product shots, logos and thumbnail cut-outs.
Upscale 2× (3 credits)
Doubles the width and height of an image. Images close to 8 megapixels are enlarged up to 8 megapixels. Upscaling works on images under 8 megapixels.
How to use them
Choose or upload an image (PNG, JPEG or WebP up to 10 MB).
Tap Remove background or Upscale 2×.
The new image appears in Assets. Your original stays as it is.
Both tools are included on every plan, including Free.
