Resize images to exactly 512x512 for stickers, emoji and square icons
512x512 is the square that shows up everywhere: WhatsApp stickers are exactly 512x512 WebP, Telegram static stickers need one side at exactly 512px, Signal stickers are 512x512 PNG, APNG or WebP, and most chat apps, avatar slots and app-icon tiles happily take a 512px square. The problem is that exact means exact. A 1000x1000 export gets rejected or silently cropped, and a 512x513 file fails a spec that only wanted one side pinned. Resizing also changes the byte count, so a square that passes the pixel check can still blow the file cap. Skwish resizes and compresses images locally in your browser with a live before/after readout per image, so you land on 512x512 and see the resulting size at the same time. Batch the whole set, export a ZIP. Nothing is uploaded to a server.

512x512 resize notes
Use these before you upload or share the page.
Exact means exact. WhatsApp and Signal want 512x512; Telegram wants one side at exactly 512px with the other equal or smaller. Pick the right target per platform.
Resize before you compress. A 2000px image compressed to 100KB still fails a 512x512 spec — geometry first, then bytes.
Watch the aspect ratio. Squashing a non-square drawing into 512x512 distorts it, so crop deliberately or keep the original ratio if the platform allows it.
