Custom Stamp with Your Business Logo
A custom stamp business logo sounds like a straight import job, and it usually is not: most brand logos do not survive becoming a stamp, and you normally find out after designing the whole thing. Drop yours in below and see exactly what one colour of ink does to it.
A stamp is ink or no ink, nothing in between. Your logo needs a real transparent background, tones that separate cleanly, and enough resolution. The checker scores all three against your actual file and shows the single-colour result live.
The three things that break a business logo on a stamp
A rubber stamp has one colour of ink and a sheet of paper. Every pixel of your logo has to become one or the other. Screens do not work that way, so the logo your designer signed off on can be perfectly good and still be unusable here. Three properties decide it, and all three are measurable — which is what the tool above is doing rather than guessing. It also checks the obvious thing first: that something actually inks at all, since a white-on-transparent export scores full marks on every other count and presses a blank.
A transparent background, not a white one
The most common failure by a distance. A logo saved as JPG, or exported as a PNG "on white", carries its own rectangle. On screen that rectangle disappears into the page. In a stamp design it does not: the opaque white block travels with the logo and covers the ring, the border and anything else it is placed over. The checker reads the alpha channel directly, so it can tell a genuinely transparent file from one that merely looks transparent against a white website.
One thing to read correctly: the preview above shows only the ink — it drops white to bare paper so you can judge the shape. The editor further down places your actual file, white rectangle and all. A logo can therefore look fine in the preview and still bring its box into the design, which is exactly why the background check is reported separately rather than left to your eye.
Mid greys have nowhere to go
Ink has no 50% setting. Anything grey in your logo has to be pushed to solid or dropped entirely, and the software has to pick. Where a mark is mostly black-and-white with crisp edges, that choice is obvious and the result looks like the original. Where a quarter of the artwork sits in the middle of the tonal range — soft shadows, a gradient fill, an anti-aliased hairline — the choice starts deciding what your logo looks like. That is why the threshold is a slider here and not a hidden constant: you should be the one making that call, with the result in front of you.
Resolution you would never notice on a website
A 150-pixel logo is perfectly sharp in a page header and ragged the moment it is scaled to stamp dimensions. Below roughly 300 pixels on the shortest side, edges start to break up. If your only copy is small, go back to the vector original — an SVG has no resolution to run out of.
What the score does not tell you
These are four measurements of the pixels, not a press proof. They read tone, transparency, size and ink coverage. They cannot see stroke weight, so a mark with hairlines thin enough to break up, or gaps tight enough to fill in with ink spread, can still pass every check and disappoint on paper. Order a proof before a production die.
It also measures the file, not the trademark. Whether you are allowed to reproduce a given mark on a stamp, and whether a stamped version still satisfies your brand guidelines, are questions the pixels cannot answer.
Now put it on the stamp
Upload the same logo in the editor below — it takes over the centre of the stamp, with your company name arcing around it.
PNG, JPG or SVG, up to 5MB. Tinted to match the ink color below and replaces the center text — 100% on-device, never uploaded.
Free exports add a small credit line and cap at 1000px.
Batch export — generate multiple stamps at oncePRO
One name per line (uses the top-text field; everything else — shape, ink, logo — stays as set above). Up to 40 rows, downloaded as a single zip of PNGs.
Want a physical stamp?
StampMakerTool only makes digital designs — we don't sell or ship physical stamps, and we're not partnered with anyone who does.
Download the highest-resolution file you have access to (SVG is best if the shop asks for vector art) and take it to a local rubber-stamp, engraving, or notary-supply shop — most accept a PNG or SVG upload directly and can quote you on the spot.
FAQ
Can I put my business logo on a custom stamp?
Yes — upload a PNG, SVG, JPG or WebP and it takes over the centre of the stamp. The part worth doing first is checking the logo is stampable at all: a stamp is one colour of ink, so gradients, mid greys and white background boxes behave very differently from how they look on screen. The checker on this page tells you before you design around it.
Why does my logo look wrong on the stamp?
Almost always one of three reasons. It has no transparent background, so the whole rectangle inks in. It relies on grey tones or a gradient, which have to collapse to solid or blank. Or it is too small, so the edges break up at stamp size. Run it through the checker above and it will name which of the three applies to your file.
What logo format works best for a stamp?
An SVG of the flat, single-colour version of your mark. Failing that, a PNG with a genuine alpha channel at 300px or more on its shortest side. Avoid the JPG from your website header: JPG cannot store transparency at all, so it always arrives with a background box attached.
Is my logo uploaded to a server?
No. Both the checker and the stamp editor read the file in your browser tab using a local canvas. Nothing about your brand assets is transmitted, which matters if the logo is not public yet.
Is exporting a stamp with a logo free?
Designing and previewing with your logo is free. Exporting the finished logo stamp is a Pro feature — text-only stamps stay free to export as transparent PNG and SVG. Pricing is on the Pro page.
