Private, browser-only editor
Turn a photo, drawing or reaction into a clean 512 × 512 WebP sticker. Nothing is uploaded, there’s no account to create, and the download only unlocks after the file passes the size and format checks.
Your image stays on this device.
Static sticker editor
Fit the subject, remove a simple background in one click, restore any detail you want to keep, and drag your caption exactly where it belongs.
JPG, PNG, WebP or AVIF works when your browser can open it. For safety, files are limited to 20 MB and 24 million pixels.
or drop an image here / paste from your clipboardDrag to position your image. Use the controls to fine-tune it.
A simple route to a useful result
You don’t need to learn a full design app. Make the few edits that matter, then let the export check handle the technical part.
Choose an image where the person, pet or reaction is large enough to recognize when it shrinks.
Drag, zoom and rotate until the important part sits away from the outer edge.
Remove a simple edge color automatically, restore any detail caught by the selection, then drag your caption into place.
WaSize tries several quality levels and only offers a WhatsApp-ready download when the real file is 512 × 512 WebP and 100 KB or less.
What “ready” means
Renaming a PNG to .webp doesn’t convert it. WaSize inspects the encoded header, opens the finished file again, confirms the 512 × 512 dimensions and checks the byte size before download.
Static stickers in WhatsApp’s official Android sample use WebP, measure exactly 512 × 512 pixels and stay at or below 100 KB. A white outline is often helpful, but it’s a design recommendation rather than a universal rule.
Straight answers
Use an exact 512 × 512 pixel canvas. For a static Android sticker pack, the official sample requires WebP at 100 KB or less. WaSize checks all three before calling the WebP download ready.
No. Your browser opens the image, applies the edits and creates the download locally. The image content isn’t sent to WaSize. Normal page analytics, if enabled, are separate and must never include your image or filename.
No. It prepares the asset. Importing a pack uses supported WhatsApp features or a compatible native sticker app. A website shouldn’t pretend that downloading a WebP or ZIP silently installs a pack.
Not in this first release. A browser needs a real animated WebP encoder and frame-level validation. The current editor deliberately creates static stickers only; it won’t save one still frame and label it animated.
Detailed photos, noise and complex transparency can take more space. Try removing more background, using a tighter crop or simplifying the image. WaSize lowers WebP quality gradually, but it won’t offer an oversized file as WhatsApp-ready.
The technical limits on this page are based on WhatsApp’s official sample app documentation. WaSize is an independent tool and isn’t affiliated with, endorsed by or sponsored by WhatsApp or Meta.
