Custom Stamp Generator
Build any stamp from scratch — company seals, monograms, dates, addresses — then download a clean transparent PNG or a true, re-editable SVG. Free, in your browser.
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.
A custom stamp generator lets you design a stamp exactly the way you want it, without learning graphics software. Type your text into the live tool above and the stamp redraws instantly: the arc text curves around the ring, the center line sits in the middle, and the ink picks up a subtle worn edge so it reads like a real impression rather than a flat clip-art circle. Everything happens on your device — your text is never uploaded — so you can iterate as many times as you like.
What you can customise
Every part of the stamp is under your control. Change the top and bottom arc text for a company name and a tagline or established year. Set the center text to initials, a monogram, a short word or a number. Switch the shape between a classic circle and a rounded rectangle for address stamps. If it is the date that has to change, the date stamp generator with seven date formats is the purpose-built face for that. Pick an ink colour — oxblood red for a traditional seal, ink black for legal documents, notary blue, forest green or violet. Toggle the small star accent on or off. The preview updates the moment you make a change, so what you see is exactly what you export.
Export: transparent PNG and true SVG
When the design looks right, download it in the format you need. The transparent PNG is a 1000×1000 pixel image with a real alpha channel, so it drops cleanly onto invoices, packaging, photos or coloured backgrounds without an ugly white box behind it. The SVG is a vector file — the rings and curved text are stored as math, so it scales to any size without blurring and stays fully editable in design tools later. There is no watermark on either format and no account to create.
Who uses a custom stamp generator
Small business owners create company seals and logo stamps for invoices and packaging. Teachers make reward and feedback stamps. Crafters and wedding planners design monograms and wax-seal motifs. Designers grab a quick vector stamp for mockups and badges. Because the export is clean and re-editable, the same tool works whether you need a one-off image today or a reusable brand asset you will tweak for years.
FAQ
Is the custom stamp generator free?
Yes. Designing and exporting a transparent PNG or SVG is completely free, with no signup and no watermark.
Can I edit a stamp again later?
Yes. Keep the SVG file — it stays fully editable, so you can reopen it and change the text or colour any time.
Will the PNG have a transparent background?
Yes. The PNG exports with a true alpha channel, so only the ink shows — there is no white or black box behind the stamp.
