Troubleshooting
04 / GUIDEIf the result looks blurry, you probably upscaled the image; lower the target size or keep upscaling off. Transparent areas become white in JPEG output — use PNG or WebP to keep them. A very large canvas may fail on devices with limited memory, so resize in smaller steps if that happens.
