A flat color that touches the edge can be cleared. Hair, shadows, and busy backgrounds will not come out cleanly. A transparent PNG, or a manual crop inside the safe frame, is the reliable path. This page does not run a large cutout model.
Download one WebP or the zip, and move the files onto your phone. Open WhatsApp, open a chat, tap the sticker icon, tap +, and choose to create a sticker. Pick the image from your photos or files. To build a pack, repeat that and add the next sticker to the same pack. This page does not install the pack for you, and it does not upload the images.
WhatsApp animated stickers have to be an animated WebP, still 512×512, at most 500 KB, with WhatsApp’s own frame rules. This page exports static stickers only, so it does not hand you an animation that will not install. An animated source keeps one frame.
