Will my photos be uploaded to a server? Is it secure?
Absolutely secure. A key feature of this tool is that all image processing is done in your browser via JavaScript. Your photo files never leave your computer, and we cannot access or store any of your image data.
What image formats are supported? Is there a size limit?
We currently support the three most common image formats: JPG (JPEG), PNG, and WebP. To ensure browser performance, we recommend uploading images under 10MB.
What is the quality of the converted image?
We use a standard weighted average method (Luma-based Grayscale Conversion). This method better simulates human eye sensitivity to different colors, resulting in a more visually natural black and white image with better detail retention. The download is saved as a high-quality JPEG.

To ensure the best compatibility and a reasonable file size, we standardize the output to high-quality JPG format for download. It is a universal format supported by nearly all devices and platforms for viewing and editing.
