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.

Animated stickers

Drop a multi-frame sheet. Line the frames up with onion-skin and scrub through to check it. Exports as animated WebP for WhatsApp, or a GIF to Photos.

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.

Erase brush

For when one tile has a smudge the auto-cutout missed. Brush it off, undo if you slip, and the brush sits where your thumb is whether you're lefty or righty.

Smart Slice

It usually figures out the grid on its own. If it doesn't, drag the dividers. Each cell is independent, so wonky sheets still slice clean.

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 or Nano Banana will spit out if you ask for one. Don't have one yet? Use the prompt builder — pick a theme, attach a photo, paste the prompt, get a sheet back.
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. iPad and Mac if there's demand.
How many stickers per pack? +
WhatsApp: 3 to 30. Telegram: 1 to 120. GridSticker enforces each platform's rules at export — keep building, then ship the same pack to either app.
Can I send the same pack to both WhatsApp and Telegram? +
Yes. Build it once, then pick where it goes. Animated packs are WhatsApp-only for now — Telegram wants a different video format I haven't gotten around to. Static packs go to either.
Can I use these in iMessage? +
Yes. From the export menu, pick Share… and then on iOS 17+ tap Add Sticker. The tile lands in your iMessage sticker library and you can drop it into any conversation. Works one tile at a time — pick the ones you actually use.
Can I make animated stickers? +
Yes. Drop a sheet where each frame is on its own row or column, line them up with onion-skin, then export. WhatsApp caps animated packs at 500 KB, so if your pack runs heavy GridSticker will quietly drop frames or dial quality down to fit.
What if the auto grid detection gets it wrong? +
Drag the dividers around. Each row and column moves independently, so even a wonky or off-centre sheet still slices clean. The cols/rows pills are right under the image.
One sticker came out wrong. Can I fix just that one? +
Yes. Tap into the tile and fiddle: outline width, tolerance, or grab the erase brush for stray pixels. The other tiles don't move.
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.
WhatsApp said "Error 1000" when I tried to add the pack. +
Tap export again. It usually goes through on the second try. This is a flaky handoff thing on WhatsApp's side, not a problem with your pack — if a third try doesn't work, force-quit WhatsApp and try once more.
