What size a seal should actually be
Smaller than you think
A seal on a digital document usually wants to land around 250 to 350 pixels wide. Bigger reads as a sticker rather than an impression, and it starts hiding the text it is supposed to endorse. The default here is 300 for that reason, not the 512 the logo and icon tools use.
One number is enough
Set the width and leave the height at zero and the aspect ratio is held for you. That matters more for a seal than for a photo: a circular stamp squashed even slightly stops reading as circular, and everyone notices without knowing why.
Down is safe, up is not
Scaling down discards pixels and stays crisp. Scaling up invents them, and on a stamp that means the rim text turns to mush — that fine ring of lettering is the first thing to go. Always start from the largest version you have.
Transparency is carried through
A knocked-out seal stays knocked out at any size, so the resized file still drops straight onto a document without a white box behind it.
If it is going to print
Screen sizing and print sizing are different problems. For print, work back from physical size at 300 DPI — a 25 mm seal needs about 300 pixels, a 40 mm one about 470.
Picking a stamp size
Start at 300 pixels wide
It reads as a real impression on an A4 page without covering the text. Adjust from there rather than guessing.
Never upscale a seal
The rim lettering is the finest detail in the image and the first thing to break. Go back to the source.
Height zero means auto
Leaving height at zero holds the ratio. A circular seal that is 2% off round is immediately noticeable.
How to resize a stamp
Upload the stamp
Bring the largest copy you have — you can always come down.
Set the width
Leave height at zero to keep the proportions. Around 300 suits most documents.

Where the size is fixed for you
Fitting a signature block
Scale a seal to sit beside a signature without overwhelming it.
Company letterhead
Match the stamp to the size the template reserves for it.
Print artwork
Hit an exact physical size by working back from 300 DPI.
Consistent document sets
Give every contract in a batch the same seal dimensions.

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.
