Post with Watermark

Protect your creative content and reinforce your brand by automatically applying watermarks to photos and videos you share across your social accounts.

Overview

A watermark is a logo or symbol placed on your media to discourage unauthorized use and promote your brand. With Publer, you can save, manage, and apply unique watermarks per account—no editing skills required.

Watermarking is available on the Professional Plan for images and the Business Plan for videos.

Step 1: Fetch Available Watermarks

Use the Media Options endpoint to get all saved watermarks for your account(s):

Response Example:

[
  {
    "id": "63c675b54e299e9cf2b667ea",
    "albums": [],
    "watermarks": [
      {
        "id": "680fa7bebd7195d33da6630d",
        "name": "Brand Logo",
        "opacity": 80,
        "size": 6,
        "position": "bottom_right",
        "default": true,
        "image": "https://cdn.example.com/watermarks/logo.png"
      }
    ]
  }
]

• Each watermark is account-specific.

• You can create and manage multiple watermarks per account in Publer.

Step 2: Schedule or Publish a Post with a Watermark

When creating or scheduling a post, specify the full watermark object in the relevant accounts array. The watermark settings will be applied to all attached media.
