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.

Storage Integration

Fetch input files directly from your object storage and write output files back seamlessly. Integrated with S3, Azure, Google Cloud, and more.

Custom Workflows

Use Jobs to chain multiple operations in a single API call — convert to multiple formats, add watermarks, and generate thumbnails all at once.

Developer Friendly

Comprehensive documentation, a visual Job Builder for generating code snippets, and free, responsive support directly from the team.
