Hey Product Hunt! 👋

I built APIWatermark because adding watermarks sounds simple, but it can become very repetitive when dealing with many assets (image,video,document).

Images, videos, PDFs, and GIFs all require different tools and processing methods. For developers, this means setting up image libraries, FFmpeg workers, PDF processing, file storage, and background jobs just to add a logo or text.

APIWatermark brings everything into one API and visual editor.

You can use it to:

• Add your logo to product images and marketing content
• Protect paid PDFs, reports, ebooks, and digital downloads
• Personalize documents with a customer’s email, IP address, or timestamp
• Watermark user-generated images and videos automatically
• Process hundreds of files in bulk
• Let non-technical team members create watermarks with the visual editor

It supports images, videos, PDFs, and GIFs, with text, logo, repeated, and dynamic watermarks.

You can try the editor without signing up, and there’s a free plan for testing the API.

I’d love to hear what formats, integrations, or watermarking workflows you’d like us to add next.

Thanks for checking it out!
