Watermark API
Add watermarks to PDFs, images, and videos with a simple API. Overlay text or images with full control over position, opacity, rotation, and styling.
Everything you need to add watermarks
A production-ready watermarking pipeline with text and image overlays, position controls, async processing, and storage integrations.
Use Text or Images as Watermark
Add text overlays with full control over font, size, color, and opacity — or stamp images and logos onto documents, images, and videos.
Add Watermarks to PDFs
Stamp text or images on PDFs with precise control over position and visibility across all pages, or a specific range of pages.
Add Watermarks to Images
Overlay text or logos on JPEG, PNG, TIFF, and other image formats. Perfect for protecting photography or branding visual content.
Add Watermarks to Videos
Burn text or image watermarks into video files. Ideal for protecting video content or adding persistent branding across frames.
Async or Sync
By default, files convert asynchronously with webhook notifications on completion. Need instant results? Use our synchronous API for on-the-fly conversion.
