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.
Often used alongside Logo to White Color Converter, Logo to Black Color Converter and Logo Outline Adder.
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
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.
