WhatsApp sticker maker: beat the 100KB WebP limit
WhatsApp has the strictest sticker spec in chat apps: 512×512 WebP at just 100KB static. The exporter walks quality and dimension passes down until the sticker fits, and renders the 96×96 tray icon every pack needs.
WhatsApp imports stickers through companion apps, so the download is a zip with correctly named WebP files plus the tray icon — drop it into any 'sticker maker' app that reads a folder and publish to WhatsApp.

| File | Format | Size | Limit |
|---|---|---|---|
| Sticker WebP | WEBP | 512×512 | 100KB |
| Tray icon PNG | PNG | 96×96 | 50KB |
How to publish on WhatsApp
- Design the sticker. Upload, template, or AI. Leave breathing room — WhatsApp insets stickers inside the 512 canvas.
- Export under 100KB. The WebP is compressed in passes until it clears WhatsApp's static limit. The tray icon comes with it.
- Import and send. Load the zip into a WhatsApp sticker importer app, publish the pack, and it appears in your sticker tray.
Questions
What format are WhatsApp stickers?
WebP at 512×512: 100KB maximum for static stickers, 500KB for animated. Packs also need a 96×96 tray icon under 50KB.
Why 100KB? My image looks fine at 300KB.
WhatsApp hard-rejects static stickers over 100KB no matter how they look. The exporter's quality/dimension passes exist for exactly this number.
Can I add stickers without building an app?
Yes — several free importer apps read a folder of spec-correct WebP files. This zip is built for that workflow.
