What a glow is, technically
A glow is a shadow with no offset
It is the same blur that makes a drop shadow, cast in a bright colour and centred rather than displaced. Because there is no offset, it spreads equally in every direction instead of implying a light source from one side.
It needs a transparent source
The glow is cast from the alpha channel, so it traces the real shape of your subject. An image on a solid rectangle glows as a rectangle, which is never the intent. Cut it out first.
Glows need a dark background
A bright halo against white is invisible. This effect only reads on dark surfaces, which is why it belongs to dark interfaces, night scenes, and neon treatments rather than light documents. Use a shadow on a light background instead.
The canvas grows
The output is larger than the input by the spread on each side, and the added margin is transparent so the file still composites cleanly.
Bake it in or use CSS
On the web a box-shadow with no offset does the same thing and stays adjustable. Bake it into the file for slides, video overlays, thumbnails, and anywhere without a styling layer.
How to add a glow
Upload the image
Drop in a transparent PNG so the glow traces the real shape.
Set the glow
Choose the colour and the spread. Wider and softer reads as ambient light; tight and bright reads as neon.

Where a glow works
Dark interfaces
Lift a logo or icon off a dark background with a soft halo.
Video overlays
Make a bug or a lower-third readable over changing footage.
Neon treatments
Build the neon-sign look from flat artwork.
Thumbnails
Separate a subject from a busy background so it reads at small sizes.
Or just ask
Describe the edit in your own words
Type what you want changed and the assistant does it on the canvas — each step lands as a layer you can reopen, so nothing it does is baked in.
