What's inside

What it actually does.

Vector contour smoothing

Traces the outline as a vector path, then smooths the corners. No staircase pixels along the edge.

Clean white outlines

The white outline that makes a sticker read as a sticker. Adjust the width to taste.

Background removal

Pick your subject and the rest gets knocked out. Or just remove the white, with a tolerance dial when the source is messy.

Per-tile fine-tuning

One sticker won't cooperate? Tweak it on its own. The rest stay untouched.

Lossless WebP

Lossless when it fits under WhatsApp's 100KB limit. Lossy when it has to. Either way, no muddy edges.

Hi-res Photos export

Save the full PNG to Photos. Transparent background intact, no compression.

FAQ

Quick answers.

What kind of image do I drop in? +
A sticker sheet. Usually 2×2, 3×3, or 4×4 stickers on a white background — the sort of thing ChatGPT, Midjourney, Sora, or Gemini will spit out if you ask for one.
Does it work with non-AI images? +
Yes. Anything in a grid on a clean background. Scanned drawings, sticker templates, photo collages — all fine.
Where does my image data go? +
Nowhere. Everything happens on your phone. Nothing gets uploaded. Full privacy policy here.
Why is it iPhone only? +
For now, yes. Built and tested on iPhone first — that's where the WhatsApp handoff works best. iPad and Mac if there's demand.
How many stickers per pack? +
WhatsApp's limit is 3 to 30. You can keep adding from different sheets until you hit the cap.
Can I use this for my Cricut? +
Yes — and the white outline is what makes it work. Generate or scan your sticker sheet, run it through GridSticker, then export the hi-res PNGs to Photos. Drop those into Cricut Design Space as Print-then-Cut images. The clean white border gives Cricut's blade something definite to follow, so you get crisp die-cuts instead of ragged edges. Adjust the stroke width to match the bleed your sticker paper needs.
