GridSticker
Peter Ong
GridSticker turns AI-generated sticker sheets into ready-to-send sticker packs for WhatsApp, Telegram, LINE, and iMessage. Drop in any sheet — 2×2, 3×3, 4×4, anything — and GridSticker slices it into individual stickers automatically. Tweak the grid by hand if it gets it wrong. Then ship the pack to WhatsApp or Telegram, bundle a LINE upload ZIP, add to iMessage stickers via the share sheet, or save the high-res PNGs to Photos. WHAT'S INSIDE • Grid-slicing for any sticker sheet — any layout, any size • Animated stickers. Drop a multi-frame sheet, line frames up with onion-skin, then export as animated WebP for WhatsApp or as a GIF to Photos • Smooth corners via vector contour tracing — no staircase pixels along the edge • The white outline that makes a sticker read as a sticker, with adjustable width • Background removal: pick your subject, or just remove the white with a tolerance dial when the source is messy • Erase brush for stray pixels the auto-cutout missed. Undo if you slip, and the brush sits where your thumb is whether you're lefty or righty • Per-tile fine-tuning when one sticker won't cooperate • Lossless WebP under WhatsApp's 100KB limit, lossy when it has to be • Hi-res Photos export with the transparent background intact WHO IT'S FOR • You generated emoji stickers in any of the popular AIs and want them as a real WhatsApp, Telegram, LINE, or iMessage pack • You scan or photograph drawings and want them clipped, outlined, and shareable • You run a Cricut and need clean white-bordered PNGs for Print-then-Cut sticker projects EXPORT TO • WhatsApp — full sticker pack in one tap, static or animated • Telegram — full sticker pack via Telegram's own importer • LINE — bundled ZIP ready to upload at creator.line.me • iMessage — Share… → Add Sticker (iOS 17+) drops the tile into your sticker library • Photos — full PNG, transparent background, no compression • Photos GIF — for animated packs you want to share outside chat apps Made on a small island, by one person. gridsticker.peterong.dev
