Grayscale Image Converter — Black and White Photo Tool

Convert color photos to black and white with our free grayscale image tool on XConverters. Upload a picture, apply the grayscale filter via transformImage with grayscale:true, choose JPEG, PNG, or WebP output, and download — all in Ihrem Browser. Kein Konto, kein Upload, völlig kostenlos.

Was dieses Tool macht

Grayscale removes color information while preserving luminance, creating classic monochrome looks for portraits, street photography, and print-style graphics. Our tool uses transformImage with the grayscale flag so conversion is fast and consistent without manual channel mixing in an editor.

Choose JPEG for smaller sharing size, PNG for lossless monochrome, or WebP for modern web delivery. Processing is entirely browserlokal on XConverters — family photos, client portraits, and product shots never upload to a server.

One-click workflow after upload: filter, format, download. Free with no registration — perfect when you need a quick B&W version for social posts, thumbnails, or artistic experiments.
