Frequently Asked Questions
How do I make a photo black and white?
Click the “B & W” filter, or drag Saturation all the way to −100 for a pure grayscale image.
Are edits applied at full resolution?
Yes. The preview is scaled to fit your screen, but the download is processed at the image's original size.
Are my images uploaded to a server?
No. Every operation runs locally in your browser using the HTML5 Canvas engine. Your files never leave your device, so they stay completely private.
Is this tool free to use?
Yes — it's completely free with no sign-up, no watermarks added to your output and no daily limits.
