Etchv

Etchv is an invisible watermarking API that adds traceable marks to images, PDFs, and video files.

Etchv provides an invisible watermarking API for images, PDFs, and H.264 MP4 and MOV videos. It embeds a unique reference into the pixels of each file as it is delivered, allowing creators and platforms to trace leaked content back to specific recipients. The service supports various formats including JPEG, PNG, TIFF, and layered PSD files while retaining text and fonts in PDFs. Users can integrate via plain HTTP, six official SDKs including Python, Node.js, Go, Rust, C#, and Java, or workflow tools like Zapier, n8n, and Make. Files can be stored in included storage for up to a year or delivered directly to Amazon S3, Google Cloud Storage, or Azure Blob Storage. Pricing starts with a free trial and monthly plans ranging from the Launch plan at $19 per month up to custom Enterprise deployments.
