Watermark API

Stamp your brand or copyright text onto an image automatically — consistent placement, every time. Try it without code first on the free watermark tool.

POST/v1/images/transform

curl https://api.pixpoo.com/v1/images/transform \
  -H "x-api-key: pxp_xxxxxxxx" \
  -F file=@photo.jpg \
  -F watermarkText="© your brand"

Parameters

filefilerequired

The source image (multipart upload). Use "url" instead to fetch from a remote address.

watermarkTextstringrequired

The text to stamp onto the bottom-right corner of the image.

formatstring

Output format: jpeg, png, webp, avif, gif, or tiff. Omit to keep the source image's own format.

Response

The image with the watermark composited onto it.

Prefer JSON with a base64 payload instead of raw bytes? Use /v1/images/transform/json with the same parameters.
