Everything you need to know about protecting your content with invisible watermarks
How do I get started with watermarking?
Simply drag and drop your files (audio, video, images, or documents) onto the upload area. Our system automatically detects the file type and applies the most appropriate watermarking algorithm. Anonymous watermarking is available without an account, or create an account for advanced features and tracking.
Getting StartedWhat types of files can I watermark?
We support comprehensive media formats: Images (JPEG, PNG, GIF, TIFF, WebP, AVIF, HEIC, HEIF, DNG), Video (MP4, MOV, AVI, M4V), Audio (MP3, WAV, M4A, MPEG), and Documents (PDF, DOCX, PPTX, XLSX, ODT, ODS, ODP, RTF, DOC, TXT, SVG). Anonymous uploads support up to 100MB per file, while authenticated users start at 1GB (both configurable per tier).
Getting StartedHow does the watermarking process work?
Our multi-layered system uses advanced mathematical transforms (DCT, DWT, FFT, SVD, MDCT, Wavelet) and NIST-approved post-quantum cryptographic signatures (ML-DSA, ML-KEM, SLH-DSA). Each file type uses specialized algorithms: spectral embedding for audio, temporal frame-based watermarking for video, frequency domain embedding for images, and structural watermarking for documents.
Getting StartedWhat is anonymous watermarking?
Anonymous watermarking allows you to protect files without creating an account. Files are processed with temporary job tracking, quantum signatures, and automatic cleanup after 24 hours. Perfect for quick content protection without registration.
