Convert any JPG, PNG, or WEBP image to black and white online for free. The Grayscale Studio offers 4 conversion modes (Standard, High Contrast, Soft Grayscale, Pure B&W), fine-tune sliders for brightness, contrast, exposure, B&W intensity and threshold, side-by-side before/after comparison with 0.25x–3x zoom, and one-click export as PNG, JPG, or WEBP with adjustable quality. All processing happens locally in your browser — your images never leave your device.

Features

  • 4 Conversion Modes — Standard, High Contrast, Soft Grayscale, and Pure B&W (with a threshold slider 0–255) to match any creative or technical need.
  • Fine Adjustment Sliders — Brightness, Contrast, Exposure, and B&W Intensity controls with live value badges, plus an Invert toggle and one-click reset.
  • Side-by-Side Compare + Zoom — Live before/after preview with 0.25x to 3x zoom and quick reset, so you can inspect pixel detail before saving.
  • PNG / JPG / WEBP Export — Download in any of three formats with dynamic file naming and an adjustable quality slider (10–100%) for JPG/WEBP.
  • 100% Private & Client-Side — Drag-and-drop or browse files up to 50 MB; every pixel is processed locally via HTML5 Canvas — nothing is ever uploaded.
