Convert logo into stamp online

Turn a logo into a stamp online free. Create a rubber-stamp style stamp logo with ink color, seal shape, and worn texture — online stamp maker in your browser.

What is a logo into stamp converter?

A logo into stamp tool (stamp logo, create stamp, online stamp maker, online stamp design maker, stamp maker online, custom stamp creator, rubber stamp online creator) restyles a brand mark as a single-color ink imprint — often circular with a border, slightly tilted, and a bit imperfect. People search “how to make a stamp” when they need that rubber-stamp look for documents or mockups without ordering a physical seal. This page thresholds the logo into ink, clips it to a seal shape, and exports a transparent PNG. For typed/drawn signatures see /signature-maker; for text watermarks on photos see /watermark-image.

Tips for better stamp logos

Cleaner rubber-stamp results.
  • 01

    Start with a clear logo

    Knock out busy backgrounds first so only the mark becomes ink.

  • 02

    Classic red for “official” feel

    Use the Classic red preset when you want a traditional office stamp.

  • 03

    Lower density slightly

    88–95% density looks stamped; 100% can look like a flat sticker.

  • 04

    Tilt a few degrees

    −6° to −12° sells the hand-pressed look.
