FAQ about Open Source Background Removers

Q1: Which is more accurate, the open source background remover or the online AI tool?

For simple images with clear edges, skilled users may get higher accuracy using GIMP. But for complex edges (such as hair and fluff), AI background removers are usually better because AI models are trained with a large amount of data and can better identify such complex patterns.

Q2: How long does it take to remove the background with GIMP?

Simple images may only take a few minutes, while complex images may take more than half an hour to refine. However, AI image editors like UltraPic usually only take 5-10 seconds if the network is stable.

Q3: Can the GIMP open source tool handle transparent objects or shadows?

GIMP can handle these complex situations thru advanced layer and mask technology, but it requires high skills.

Q4: Do these tools support batch processing?

GIMP can achieve batch processing thru Python scripts, but it requires programming knowledge. UltraPi provides an intuitive batch processing interface. You only need to upload your images in batches and click Batch Remover to remove the background.
