Tips
- All processing happens locally in your browser — images are never uploaded.
- PNG preserves transparency; JPG produces smaller files with adjustable quality.
- Very large images may be auto‑downscaled to avoid browser memory limits.
- For strict black/white (no grays), apply thresholding in a future update.
FAQs
Is this grayscale converter private?
Yes. All processing happens locally in your browser — your images never leave your device.
What formats are supported?
Upload PNG, JPG/JPEG, or WebP. Export to PNG (lossless) or JPG (smaller, adjustable quality).
Will my image quality change?
PNG preserves original quality. JPG lets you choose a quality level (50–100%) for smaller files.
Can I get pure black and white (no gray)?
This tool uses perceptual grayscale. A threshold option for true black/white is planned.
