Protect Your Images With Invisible Precision

sylentID is a professional digital-watermarking plugin for Photoshop that embeds invisible ownership data directly into your images. Using advanced steganography and industry-standard metadata techniques, it safeguards your creative work without altering how it looks — giving you silent, reliable protection in every file. sylentID – User Manual

Two Systems, One Secure Identity

sylentID combines robust pixel-based watermarking (DCT, LSB, or Combined) with XMP metadata injection to create a dual-layer protection system. Your ownership details, image IDs, timestamps, URLs, and optional cryptographic signatures are securely embedded and remain attached through editing, exporting, and cross-platform workflows. sylentID – User Manual

Built for Professional Photoshop Workflows

Designed as a streamlined UXP panel, sylentID integrates naturally into your existing process: embed watermarks with a single click, manage copyright registration data, preview changes, process multiple images at once, and configure your preferred defaults. Batch tools, timestamp options, and flexible sensitivity controls allow you to tailor protection for any project. sylentID – User Manual

Reliable, Consistent, and International

With full support for multi-language interfaces, metadata standards, and cross-platform operation, sylentID ensures your embedded information travels safely wherever your images go. Licence verification, local settings storage, and optional cryptographic signatures deliver a secure and dependable experience for professional creators.

  2. Internet Connection
  3. Valid Licence Key from Gumroad/Lemon Squeeze or an Adobe Cloud Account

*Please note this plugin has the following built in languages: English, English US, Français, Deutsch, Español, Italiano, Português, Ελληνικά and 日本語

  • There is a projected release date for V.1.0.0 for January 2026.
  • In an incredible series of events and the release of Photoshop 27, there was a break in the code that allowed XMP data to be written from the UXP environment. Mainly due to security and a new pipeline built to deal with Content Credential data. For that reason, the past 3 days has been used to find a solution. Luckily a new more robust data saving XMP engine has been designed and is being deployed into th app. So V 1.1.0 is still set for January release.

Release Notes:

Changed

  • **XMP Write Pattern — No Dirty Pixel**
  • Replaced save interception pattern with direct `performXMPFilePatching` call in `lib/core/xmpEngine.js`
  • XMP now written directly to disk on watermark embed — no invisible pixel, no re-encode

  • Removed verification block (500ms delay + re-read) from `performXMPFilePatching`
