GridSticker turns AI-generated sticker sheets into ready-to-send sticker packs for WhatsApp, Telegram, LINE, and iMessage. Point the camera at something and snap it straight into a sticker. Or drop in a video and get animated ones. Start free — your first pack costs nothing, with every tool and every export included. No watermark, nothing held back. GridSticker Pro is a one-time unlock for unlimited packs after that. One payment, no subscription. Drop in any sheet — 2×2, 3×3, 4×4, anything up to 10×10 — 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 in one tap, build a LINE Creator ZIP ready for upload, send a real sticker pack to iMessage, or save the high-res PNGs to Photos. WHAT'S INSIDE • Grid-slicing for any sticker sheet — any layout, any size, up to 10 rows × 10 columns • Video import — drop in a clip and get animated stickers, with the frame rate set per sticker • Camera capture — snap a photo and the subject gets cut out for you. Continuous shooting keeps the camera open, with flash, rotate, and delete right there • Custom sticker tray — browse curated packs, drag the ones you want into your own mix • 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 Creator — bundled ZIP with the right sticker dimensions, main image, and chat-tray icon, ready to upload at creator.line.me • iMessage — a real Messages sticker pack, in your Stickers tray in one tap • Photos — full PNG, transparent background, no compression • Photos GIF — for animated packs you want to share outside chat apps Made on a small island. gridsticker.peterong.dev
Atelier Post

Your artwork deserves more than a quick phone photo and a caption. Atelier Post is a small, beautiful studio for presenting your work the way it should be seen — framed with care, organized as a series, and ready to share as an image or a video. No account, no clutter, nothing leaves your device. FRAME EVERY PIECE Drop in a photo and it's set in a clean, minimal frame with your title, medium, date and signature — at its true proportions, never cropped. MAKE IT YOURS Adjust exposure, contrast, saturation and warmth. Straighten, fix perspective, lift a plain background. Sign it your way — type it, draw it by hand, or import your real signature. TELL A BIGGER STORY Gather works into a grid or a 3×3 mural, give the set a title and a concept, and apply one consistent look across the series — so it reads as a body of work, not scattered posts. BRING IT TO LIFE Turn a series into a slideshow video for Reels and Stories — with gentle motion, rhythm presets, transitions and a line of text over your work. Export a high-resolution image or MP4, or share straight to Instagram. QUIET BY DESIGN Eight languages. Works offline. No account, no tracking — your art stays on your device, always. Built for artists who think in series, not just single posts.

Verdict
The clearest difference is in-app purchases: Atelier Post at none against GridSticker's 1. Atelier Post also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and ads there is nothing between them.
