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.
