Frequently asked questions
Are my images uploaded anywhere?
No. Compress, convert, resize, blur, or remove backgrounds: everything happens in your browser using the Canvas API. Your images never leave your device.
What image formats do you support?
PNG, JPEG, and WebP are supported across all image tools. Some tools also work with GIF and BMP inputs.
How does background removal work without an AI service?
Our background remover uses colour-based pixel removal: pick a background colour and a tolerance, and matching pixels become transparent. It's fast and free, and works well for solid backgrounds.
