Common questions
Is it true grayscale?+
Yes — colour is fully removed using the browser's grayscale filter, not a faux tint or low-saturation trick.
What format is the output?+
PNG, to keep the result lossless and optionally support transparency.
Private?+
Yes — 100% in your browser, never uploaded.
Which input formats are supported?+
JPG, PNG, and WebP. The output is always PNG for lossless quality — run it through PNG-to-JPG afterwards if you need a smaller JPEG.
