Create a Custom Stamp Online — Free, Forever
SimpleStampMaker is a free online stamp generator that runs entirely in your browser. Design a circle, rectangle, or diamond stamp with your own text, logo, and ink color — then download it as a transparent PNG ready to drop into PDFs, contracts, invoices, or printed documents. No signup. No watermark. No upsell. Just a working tool.
Most online stamp makers ask for an email, paywall the high-quality export, or stamp their own brand onto your design. This one doesn't. Make as many stamps as you want, use them however you want.
How to Make a Stamp Online
- Pick a shape — circle, rectangle, or diamond. Circle stamps support curved arc text on the top and bottom.
- Choose an ink color — pick from six presets (crimson, navy, forest, plum, gold, black) or use the custom color picker.
- Add your text — type your main text and an optional secondary line. Choose from five fonts including typewriter, bold display, and serif.
- Upload a logo or icon (optional) — add a signature, monogram, or company mark and adjust its size and position.
- Tweak the details — border thickness, double-ring, and stamp opacity. Lower opacity gives the aged, weathered ink look.
- Download — hit the download button and get a transparent PNG instantly.
