Watermark Tool

Protect your images with DCT watermarking and videos with Meta's VideoSeal AI

Invisible watermarks protect your content by embedding your message directly into the file, not just metadata, which can be stripped.

Your message
Use something uniquely yours: your name, email, company, or project ID. The more specific to you, the stronger the evidence if your ownership is ever disputed. E.g. Jane Smith Photography, © Acme Corp 2026, job-4471.
Processing time
Images watermark in seconds. Videos take 1–15 minutes because Meta’s VideoSeal AI runs a neural network across every single frame — this is what makes the watermark survive re-encoding, compression, and social media uploads.
Proof of ownership
Your message is embedded in the file and recorded in a timestamped certificate tied to your account. If your watermark is later detected in someone else’s copy, that certificate is your evidence you owned the original.
DCT Spread-Spectrum Watermarking: Professional-grade invisible watermarks embedded in the frequency domain. Survives JPEG compression, social media uploads, cropping, and resizing. Typically 2–10 seconds to process.
Embedded invisibly using DCT spread-spectrum β€” survives JPEG compression, resizing, and social media uploads. Detection combined with your certificate is timestamped evidence of ownership.
Use something uniquely yours: your name, email, company, or copyright notice. E.g. Jane Smith Photography  ·  © Acme Corp 2026  ·  client-job-4471
How it works: Two versions are created: a clean version with only the invisible DCT watermark (for licensed delivery or personal use) and a visible watermark version with text burned on top (for sharing, proofing, or deterring casual theft). Both are saved to My Files. The invisible watermark proves ownership even if someone removes the visible overlay.

VideoSeal AI Watermarking (Meta AI Research): Neural network-based watermarks designed to resist H.264/H.265 compression, re-encoding, and format conversion. Max 2GB. GPU-accelerated processing time varies by video length.
GPU-Accelerated Processing: Up to 2GB videos (10+ minutes 4K). Processing time varies by video length. High-bitrate videos are automatically optimized.
Embedded invisibly into every frame. Use something uniquely yours: your name, email, company, or copyright notice. E.g. Jane Smith Photography  ·  © Acme Corp 2026  ·  client-job-4471
Higher strength = Better detection. Strong (recommended) achieves 70-89% confidence. Standard achieves ~30-40%. All strengths are invisible to the human eye.
How VideoSeal works: A neural network runs across every frame, embedding your message in a way that survives H.264/H.265 re-encoding, compression, and social media uploads β€” this is why processing takes 1–15 minutes. Standard metadata is stripped when videos are shared online; neural watermarks are not. Detection of your watermark combined with your certificate is timestamped evidence of original ownership.
How it works: Two versions are created: a clean version with only the invisible watermark (for licensed delivery) and a visible watermark version with text burned on top (for sharing or proofing). Both are saved to My Files.

Verify Video/Frame Watermark

Batch Processing: Watermark or verify multiple files at once, up to 10 files on trial, up to 50 files on Pro. Supports images (PNG, JPG, WebP, BMP, TIFF) and videos (MP4, MOV, AVI). All watermarked files are saved automatically to My Files and are also available to download as a ZIP archive.
How it works: For videos, VideoSeal runs a neural network across every frame, embedding your message in a way that survives re-encoding, compression, and social media uploads β€” this is why each video takes 1–15 minutes. For images, DCT spread-spectrum hides your message in the frequency domain and processes in seconds. Neither is visible to the eye. Detection of your watermark combined with your certificate is timestamped evidence of original ownership.
