Frequently Asked Questions

How does green screen removal work?
The chromakey filter identifies pixels matching your chosen key color and makes them transparent. Adjust the similarity slider to control how strictly colors are matched.
Can I remove a blue screen instead of green?
Yes, click the key color picker and select the blue you want to remove. Any solid color background can be removed.
What if the edges look rough?
Increase the Edge Blend slider for softer transitions between the subject and the removed background. You may also need to fine-tune the Similarity slider.
Is this chromakey tool free?
Yes, completely free with no watermark or limits. All processing happens in your browser using FFmpeg WebAssembly.
