Background Filler

When a seal needs paper behind it

01

Filled behind, not painted over

The colour is composited underneath the ink, so it appears only where the image is transparent. The seal itself is never covered, and its soft edges blend into the new colour rather than against a checkerboard.

02

The black rectangle problem

Plenty of systems render transparency as black. A transparent seal that looks right on your screen can arrive as a black block in an email client or an older document viewer, which is a conspicuous way for an official document to go wrong.

03

Portals that only take JPG

Many government and banking systems accept JPG alone, and JPG has no alpha channel. Converting a transparent seal straight to JPG lets the encoder choose the fill. Choosing it yourself means you know exactly what the reviewer will see.

04

Match the paper, not just white

Pure white suits a white page. If the seal will sit on a cream certificate or a tinted form, sample that colour instead — a near-miss is more noticeable than an obvious contrast, because the eye finds the rectangle edge immediately.

05

Nothing shifts

Only transparent pixels are filled. Width and height are unchanged, so the seal stays exactly where it was. Use Add Padding if you also want space around it.

How to add a background to a stamp

1

Upload the stamp

Drop in a transparent seal PNG, or any stamp image you want flattened.

2

Pick the paper colour

White by default. Match the exact colour of the document the seal will sit on if it is not plain white.

Where a solid background is required

Email attachments

Stop a transparent seal arriving as a black block in a client that ignores alpha.

JPG-only uploads

Prepare a seal for portals that reject PNG, deciding the fill yourself.

Official submissions

Meet strict file requirements without leaving the background to an encoder default.

Print runs

Give the printer a defined background instead of letting them assume one.

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.
