Logo to Stamp Converter

Uploads a logo PNG, recolors it to a single flat ink color, then applies a seeded, edge-weighted distress erosion (interior pixels rarely disappear, edge pixels erode far more often) plus a uniform ink-opacity fade, producing a worn rubber-stamp-style impression of the logo. A free online tool from Staaarter, right in your browser.

Overview

Introduction

This tool turns a logo into a worn, single-ink rubber-stamp impression, entirely in your browser.

It's a stylized effect for giving a clean digital logo the rustic, hand-stamped look of an ink impression on paper.

What Is Logo to Stamp Converter?

A client-side effect generator that first flattens a logo to one solid ink color (reusing the same recoloring step the silhouette converter uses), then applies two new effects layered on top: edge-weighted distress erosion and a uniform ink-opacity fade.

The result mimics how a real rubber stamp's ink impression looks worn and uneven, especially around its edges, rather than a perfectly crisp printed shape.

How Logo to Stamp Converter Works

Every visible pixel is first recolored to the chosen ink color, then a seeded pseudo-random generator decides whether each pixel erodes to full transparency — pixels on the logo's outer edge (detected by checking whether any of their four neighboring pixels is transparent or off-canvas) get a much higher erosion chance than interior pixels.

Pixels that survive erosion have their alpha scaled down uniformly by the chosen ink opacity, simulating a stamp pad that isn't laying down full-strength ink.

When To Use Logo to Stamp Converter

Use it to create a rustic, hand-stamped visual treatment of a logo for branding that wants a vintage or artisanal feel.

It's also useful for mockups of physical rubber-stamp branding, like packaging or letterpress-style print materials.

Features

Advantages

  • Runs entirely client-side; your logo file is never uploaded anywhere.
  • The seeded distress pattern is fully reproducible, so you can regenerate the exact same worn look later.
  • Edge-weighted erosion produces a far more realistic ragged-stamp look than uniform random noise would.

Limitations

  • This is a stylized approximation of a rubber stamp's texture, not a physical ink-and-paper simulation — it doesn't model paper absorption, pressure variation, or ink bleed.
  • Very small or thin logo details can erode away almost entirely at high distress amounts, since there's less interior area for those pixels to fall into the low-erosion-chance category.

Examples

Create a classic red ink stamp

Input

A logo PNG, ink color #b22222, distress 35%, ink opacity 85%

Output

The logo recolored to a worn brick-red impression with a ragged edge and slightly faded ink

Moderate distress and opacity settings produce a believable, not-overdone stamped look.

Create a heavily worn black stamp

Input

A logo PNG, ink color black, distress 80%, ink opacity 60%

Output

A heavily eroded, faded impression that looks like an old, well-used stamp

High distress and low opacity together produce a much rougher, more degraded ink impression.

Best Practices & Notes

Best Practices

  • Start with a moderate distress amount (25-40%) and adjust up or down after previewing, since very high values can erode away fine logo detail entirely.
  • Use a bold, simple source logo — intricate fine lines can disappear almost completely at higher distress settings.

Developer Notes

The ink-recoloring step reuses the already-shipped convertPngToSilhouette rather than re-deriving a fill loop; the edge-weighted distress erosion and ink-opacity fade are genuinely new per-pixel logic (driven by the same mulberry32 seeded PRNG the noise-adder tool uses) since no equivalent stamp-style texture effect exists elsewhere in this category.

Logo to Stamp Converter Use Cases

  • Creating a vintage rubber-stamp visual treatment of a brand logo
  • Mockups for packaging or letterpress-style print materials
  • Generating a stylized 'approved' or 'authentic' stamp graphic from a logo mark

Common Mistakes

  • Setting distress amount very high on a logo with thin, delicate lines and being surprised how much detail erodes away.
  • Expecting a photorealistic ink-on-paper simulation rather than a stylized graphic effect.

Tips

  • Reuse the same seed value if you want to fine-tune ink opacity or color without changing the underlying distress pattern.
  • Pair with the space adder afterward to give the stamped logo some print-safe margin.
