WhatsApp stickers are a fun way to personalise your chats. Creating custom stickers from your own photos requires the image to be in a very specific format. Here is exactly what you need and how to get there for free.

How to Create WhatsApp Sticker Images
Start with a PNG image with a transparent background (remove the background using imgresizr.com's background remover). Crop to a 1:1 square, then resize to 512×512 pixels. Convert to WebP format using imgresizr.com's Convert tool — set quality to 75% to stay under the 100KB limit. Download the WebP file and import it into a WhatsApp sticker creation app (Sticker Maker on Android/iOS) to add it to your chat.
Step-by-Step Sticker Creation
- Start with a high-quality photo or image
- Remove the background to get a transparent PNG
- Crop to 512×512 pixels with imgresizr.com
- Convert to WebP at 75% quality (should be under 100KB)
- Import into Sticker Maker or another WhatsApp sticker app
- Add to WhatsApp via the sticker app's share function
Tips for Great WhatsApp Stickers
- Simple subjects with clean edges work much better than complex backgrounds
- High contrast between the subject and background makes stickers more readable in dark chat themes
- Leave a little padding around the subject — touching the edges looks cramped
- Test your sticker in a chat before sharing the full pack
