Frequently Asked Questions
How does the AI background removal work?
Krunkit uses RMBG-1.4, an advanced AI segmentation model that runs entirely in your browser via WebGPU/WASM. It analyzes the image to identify the foreground subject and creates a precise mask to remove the background.
Is it really free? What's the catch?
Yes, completely free with no watermarks or limits. The AI model runs in your browser, so there are no server costs. Your images are never uploaded anywhere.
Why does the first use take longer?
The AI model (~44MB) needs to be downloaded once. After that, it's cached by your browser and loads instantly on future visits.
What image types are supported?
JPEG, PNG, WebP, and AVIF images up to 50MB each. The output is always PNG to preserve transparency. You can optionally choose a solid background color.
Can I process multiple images at once?
Yes! Drop up to 10 images at once for batch processing. Each image is processed independently, and you can download all results as a single ZIP file.
Does it work on phones and tablets?
Yes, it works on modern mobile browsers. Processing may be slower on lower-end devices due to the AI computation involved.
