WebP Support: Upload and Export Without Conversion

Good news for anyone working with images straight from the web: remover.bg supports WebP files end to end. You can upload WebP images directly — no conversion step required — and even export your finished result as WebP, both in the online editor and through the API.

What does this mean for you?

WebP has become the default format for images downloaded from the web. Until now, working with them often meant an annoying detour: convert to PNG or JPG first, then edit. With remover.bg you can skip that step entirely. Upload the WebP file as-is, and the AI removes the background automatically. That saves editing time and keeps your workflow moving.

Where can you use WebP files?

WebP is supported across:

• Online editor — input and output
• API — input and output

Online editor: full input and output support

Simply upload or drag and drop your WebP image to remover.bg, and the AI will remove the background in seconds. There's no need to convert your image beforehand — remover.bg handles the format for you seamlessly.

And unlike most background removal tools, the remover.bg editor doesn't stop at input: when you're done editing, you can export your result as WebP too (alongside PNG and JPG). WebP keeps full alpha transparency like PNG, but at a noticeably smaller file size — ideal if the image is headed straight back to the web.

API: both input and output support

If you're using the remover.bg API, you get full flexibility on both ends:

• Upload WebP files up to 10 MB
• Download processed images in WebP format, too

How to set WebP as your output format via the API

When calling the API, choose your output format with the format parameter. By default the API returns a PNG with full transparency. To request WebP output with alpha transparency, set format to webp:

curl -X POST "https://api.remover.bg/remove-bg?format=webp" -H "Authorization: Bearer rmbgYOURAPI_KEY" -F "file=@product.webp"

Available options:

• png — full transparency (default)
• jpg / jpeg — smaller file, no transparency
• webp — transparency at a smaller file size than PNG

For jpeg and webp, you can also pass a quality parameter (0–1) to control compression.

See the API documentation for the full reference, or try remover.bg yourself — it's free to start.
