Frequently Asked Questions
How does the greyscale image converter work?
Our tool uses advanced HTML5 canvas technology to process your images directly in your browser. It analyzes each pixel’s color values and converts them to corresponding greyscale values using luminance calculations, preserving the original image’s contrast and detail.
What image formats are supported?
The converter supports all major image formats including JPG, JPEG, PNG, GIF, BMP, and WebP. You can upload images up to 10MB in size, and the tool will automatically detect and process the format.
Is my image data safe and private?
Absolutely! Your images are processed entirely within your browser using client-side JavaScript. No image data is ever uploaded to our servers or stored anywhere. Your privacy is completely protected, and you have full control over your images.
Can I use this tool on my mobile device?
Yes! Our greyscale converter is fully responsive and works perfectly on smartphones and tablets. The interface adapts to your screen size, making it easy to upload, convert, and download images on any device.
What’s the difference between the download formats?
PNG offers the highest quality with lossless compression, perfect for professional use. JPEG provides smaller file sizes with slight compression, ideal for web use. WebP is a modern format that offers excellent compression with good quality, supported by most modern browsers.
Are there any limitations or costs?
The tool is completely free with no registration required. There are no watermarks added to your images, and you can convert unlimited images. The only limitation is the maximum file size of 10MB per image, which accommodates most standard photos.
How do I get the best greyscale results?
For optimal results, use high-resolution images with good contrast. Images with strong lighting differences will produce more dramatic greyscale effects. The tool automatically optimizes the conversion, but starting with a well-lit, high-quality color image will yield the best black and white results.
