What adding a background changes

01

Filling behind, not painting over

The colour is composited underneath your image, so it only appears where pixels are transparent. Your subject is never covered, and semi-transparent edges blend into the new colour instead of against a checkerboard.

02

The black square problem

Some apps render transparency as black rather than white. A transparent logo that looks right on a white page can turn into a black block in a messaging app, an email client, or a slide template. Filling the background yourself decides the answer instead of leaving it to the renderer.

03

What JPG does to transparency

JPG has no alpha channel, so converting a transparent PNG straight to JPG fills the gaps with whatever the encoder defaults to, which is usually white. Choosing the colour first means the result is deliberate rather than accidental.

04

Choosing the colour

Match the surface the image will sit on. For a white page use pure white, for a dark interface sample the actual background, and for print ask for the paper colour. A near-miss is more visible than an obvious contrast, because the eye finds the rectangle edge instantly.

05

The canvas is unchanged

Only the transparent pixels are filled. The width and height stay exactly as they were, so nothing shifts and no padding is added. To grow the canvas as well, use the Add Padding tool.

How to add a background colour to an image

1

Upload your image

Drop in a transparent PNG, or any image if you just want to flatten it. The original stays on the left.

2

Pick the background colour

Choose a hex value. The fill appears behind your subject immediately, so you can see how the edges blend against it.

Where a solid background is needed

Email and messaging

Stop a transparent logo from turning into a black block in clients that do not handle alpha.

Preparing for JPG

Decide the background colour yourself instead of letting the encoder default to white.

Print artwork

Give a cut-out a defined background so the printer is not guessing what sits behind it.

Slides and documents

Match a logo to the exact slide or page colour so no rectangle edge shows.

What people use it for

The jobs the editor was built around — and what it does differently on each one.

Colourways you can revisit

Every edit is a layer, not a bake. When the brand shifts, reopen the file and change the colour rather than rebuilding the variant from the original.

Cutouts with awkward edges

AI background removal that keeps hair, foliage and soft shadows instead of stamping a hard outline around them. The output is a transparent PNG, ready to place.

No export, edit, re-import loop

The Framer plugin runs on the canvas you are already working in, so a recolour or a cutout does not mean a round trip through a second application.

Ten options in the time one used to take

Recolour once and step through the alternatives, so a client review can look at the whole range instead of the one version there was time to make.

Brand colours matched exactly

Pick a colour straight off an existing asset and get the hex, rather than eyeballing it against a screenshot and hoping it is close enough.

Free to preview, priced per export

Previewing is unlimited and costs nothing. A credit is spent only when you download a full-resolution file, so exploring an idea is never the expensive part.
