What Is a Black & White Image Converter?
A black and white image converter helps you make image black and white by removing color while preserving light and shadow. It is ideal when you need to make image black and white for documents, archives, or learning materials. There are two common outputs. Grayscale keeps smooth tonal steps from deep black to bright white, so photos look natural and detailed. Pure B/W uses a threshold to push every pixel to full black or full white, which is perfect for line art, scans, logos, and bold graphic styles. Grayscale is best for portraits and scenes with subtle lighting, while Pure B/W works well for clean edges or readable text. Our converter runs locally in your browser, so files never leave your device. It supports single photos and batch uploads, and works with JPG, PNG, WEBP, and HEIC. Switch modes at any time and adjust the threshold to control contrast and edge clarity.
Why Choose Our Black & White Tool?
Privacy matters, so all processing happens on your device. You can make image black and white without uploads or accounts. The page loads fast, works on desktop and mobile, and requires no sign-up or watermarks. Batch handling lets you process up to 30 images at once, while rotation tools help fix orientation before export. You can keep the original format or choose JPG, PNG, or WEBP with optional compression, and HEIC files from iPhone are supported. We keep the interface simple so you can focus on the result, but the underlying conversion preserves tonal detail and clean edges for professional output.
Popular Use Cases
Black and white conversion is popular for portraits, street photography, and landscapes because it emphasizes shape, light, and texture. Designers use it for product mockups, thumbnails, mood boards, and vintage themes. Teachers and students convert charts or screenshots to reduce visual noise when studying. For documents and hand-drawn sketches, Pure B/W helps create crisp, printable images. It is also useful for archiving old family photos or preparing e-commerce catalogs with a consistent monochrome look. If you want to make image black and white for a vintage or editorial look, grayscale is often the fastest choice.
How to Use
Step 1: Upload Your Images
Upload a single photo or a batch of images. The tool accepts JPG, PNG, WEBP, and HEIC up to 20MB each. Once files are loaded, previews appear instantly so you can make image black and white without waiting or sending files to a server.
Step 2: Choose a Mode
Choose between Grayscale and Pure B/W. Grayscale keeps smooth tonal transitions for natural photos, while Pure B/W uses a threshold for strong contrast. If you select Pure B/W, move the slider to control where tones flip from black to white and fine-tune detail in shadows and highlights. If you want to make image black and white with a bold graphic style, pick Pure B/W.
Step 3: Download the Result
Pick a format and compression level, then download after you make image black and white. Single images save immediately, and batches are packaged into a ZIP file for convenience.

We support JPG, JPEG, PNG, WEBP, and HEIC. When you make image black and white, the same size limits apply. Each file can be up to 20MB, and you can upload up to 30 images per batch to keep performance smooth. If a file is larger, consider resizing first.
Compression reduces file size and can slightly lower image quality. Use No compression for maximum fidelity, or choose 90%, 70%, 50%, or 30% when smaller files are more important than perfect detail.
