Frequently asked questions
How does the glow effect work?
The tool draws your original image, then overlays a blurred copy in screen blend mode. Screen compositing only brightens pixels — the overlap of bright areas in the blurred layer creates a luminous halo or bloom effect.
Is the glow tool free?
Yes — completely free and unlimited. No signup, no account, no watermark, no daily limit.
Are my files uploaded to a server?
No. The glow effect is applied entirely in your browser on your device. Your image never leaves your computer, so it stays fully private.
When should I use the glow effect?
Glow works best on bright subjects — portraits, product shots with bright backgrounds, or night-light photos. It adds a dreamy, soft-focus quality by blooming the light areas outward.
