Short answer: make each sticker as a transparent 512×512 WebP, keep each static file at 100KB or less, then add at least 3 finished stickers to the sticker app or WhatsApp import flow you use on your phone. If you get the file format, size, and padding right before you import, the rest is straightforward.
Step-by-step workflow
1. Pick one sticker idea that reads instantly
Start with one face, mascot, object, or reaction that still makes sense on a small phone screen. Tight crops work better than busy scenes. If the image is confusing at a glance, it will not improve once it becomes a sticker.
2. Clean the art on a transparent square canvas
Remove the background, center the subject, and leave a little empty space around the edges so the sticker does not feel cramped. Test it on light and dark backgrounds. A thin white outline is a safe default when edges disappear into the chat.
3. Export the final file to WhatsApp spec
Resize the finished sticker to exactly 512×512 pixels and export it as WebP with transparency. For a standard static pack, keep each file at 100KB or less. If a file is too large, simplify the artwork, reduce gradients, or lower WebP quality a little instead of changing the canvas size.
4. Build a small pack before you import
Put related stickers together and keep the style consistent. WhatsApp packs need at least 3 stickers and can hold up to 30. For most people, a focused pack of 6 to 12 stickers is faster to finish and easier to use than trying to fill all 30 slots at once.
5. Add a tray icon and test the pack on your phone
Make a simple tray icon at 96×96 pixels, then import the pack into your sticker maker or WhatsApp-compatible flow and send a few stickers in a real chat. Check that the edges stay clean, the subject is centered, and nothing feels too small once it is actually used.

- Format: WebP with transparency
- Static file size: 100KB or less per sticker
- Pack size: 3 to 30 stickers
- Tray icon: 96×96 pixels and 50KB or less
- Keep static and animated stickers in separate packs
Common mistakes and how to avoid them
Exporting PNG or JPG as the final file
PNG is fine while you are editing, but the finished WhatsApp sticker should be WebP. Convert at the end and double-check that transparency survived the export.
Using artwork that is too detailed
Tiny lines, gradients, and busy backgrounds push files over the size limit and look muddy on mobile. Simplify the shape language before you keep lowering compression quality.
Letting the subject blend into chat backgrounds
Transparent stickers sit on white, dark, and patterned chats. Test both extremes and add a subtle white stroke if the edge disappears.
Fixing file size by changing dimensions
WhatsApp wants exactly 512×512. Keep the canvas size fixed and reduce file weight with cleaner artwork, lighter compression, or less empty visual noise.
Trying to finish the whole pack before testing one sticker
Import one or two finished files early, send them in a chat, and check readability before producing the entire set. That catches bad padding, blurry exports, and weak compositions before they spread across the whole pack.
