Convert color images to grayscale or pure black and white — for print-ready artwork, a consistent monochrome look across a set of photos, or turning a scanned document into a clean, ink-saving two-tone version. Conversion happens in your browser, so your images are never uploaded.
Three steps: drop your images in, choose Grayscale or Pure black and white, then process and download. Grayscale preserves the full tonal range, which is what you want for photographs. Pure black and white forces every pixel to one extreme — high contrast, tiny files, ideal for scanned text and line art, but soft gradients collapse entirely. Drag in multiple images and they're processed one by one and packaged as a zip. The original file format is preserved.
Frequently asked questions
- What's the difference between grayscale and pure black and white?
- Grayscale keeps every shade between black and white, so photographs still read naturally. Pure black and white (thresholding) allows only two values, giving hard contrast and the smallest files — great for text scans, wrong for portraits.
- Can I convert many images at once?
- Yes. Drop in up to 50 images and they're processed one by one and packaged as a zip.
- Do my files get uploaded?
- No. Conversion runs locally in your browser and your images never leave your device.
- Are there usage or file-size limits?
- Runs are unlimited. Files can be up to 50 MB, and batch tools accept up to 50 files at once.
