Sticker pack maker for several photos at once
This sticker pack maker turns a whole batch of photos into stickers instead of one at a time: drop up to 30 images – the chain cuts out each subject, adds a white border and saves everything in WhatsApp format (512 × 512 pixels, WebP, under 100 KB) with a tray icon, bundled as a ZIP. It all happens in your browser.

How it is calculated
How the sticker pack is made
- Remove background: an AI model (BiRefNet) finds the main subject in each photo and makes the rest transparent. It runs on your device; the model loads once and is reused for every image.
- White border: an outline around the cut-out subject, like a printed sticker, with an optional soft shadow.
- Pack: each image is fitted into 512 × 512 pixels and compressed to stay under 100 KB. A 96 × 96 tray icon is made from the first sticker. Download everything as one ZIP.
What WhatsApp and Telegram require
According to WhatsApp’s official guidelines, a sticker pack needs 3 to 30 stickers, each exactly 512 × 512 pixels in WebP format and at most 100 KB when static, plus a 96 × 96 pixel tray icon (at most 50 KB). The chain checks this and flags stickers that came out too large. For Telegram, choose PNG: Telegram requires static stickers with one side exactly 512 pixels, which you send one by one to the official @Stickers bot.
Limits
WhatsApp itself does not import ZIP files; you add your own pack through a sticker app that creates WhatsApp packs, or send the stickers individually. Cut-outs work best with one clear subject against a calm background; hair and transparent objects may show edges. With many large photos, older phones can take a few minutes.
Frequently asked questions
How do I make a WhatsApp sticker pack?
Drop at least three photos above, click “Make sticker pack” and download the ZIP. It contains all stickers in WhatsApp format and the tray icon. Use a sticker app for WhatsApp to turn them into a pack.
How many stickers can a pack have?
On WhatsApp at least 3 and at most 30. This chain accepts up to 30 photos at once.
Are my photos uploaded?
No. The AI model is downloaded once from this website and then runs on your device. Your photos and stickers never leave it.
Why is one sticker larger than 100 KB?
Very detailed subjects sometimes cannot be compressed enough. A calmer photo or a tighter crop helps. Such stickers are marked in red in the result.
Can I add text to a sticker?
For meme-style text use our single-image Sticker Maker; the pack is meant for many photos without text.
How do I drop a failed sticker from the pack?
Click the × under the sticker in the result. It disappears from the preview and from the ZIP, and the tray icon is then built from the first remaining sticker. A WhatsApp pack still needs at least 3 stickers afterwards.
