Embed invisible tracking IDs into your exclusive images. When a leaked copy still preserves the mark, Foddo Inspect traces it back to the subscriber who received that copy. Invisible by default, visible when you choose. 100% local processing.
A resilient, invisible digital signature hidden inside your image files
Strongest for original files, mild JPEG resaves, and light edits
Give Foddo your master image and a CSV list of subscribers. In seconds, it generates a unique copy for every person, embedding their specific Recipient ID invisibly into the file.
Found a suspicious repost on Telegram, Reddit, or a private group? Download the actual file and drop it into Foddo's Inspect Tool. If the invisible mark survived that route, it reveals the Recipient ID, timestamp, and author data.
Batch read, write, and clear metadata in Foddo's Metadata Editor (copyright, author, keywords, and comments) as a separate prep step before distribution.
Batch resize, convert formats, apply color corrections, and add custom text or logo watermarks to thousands of images at once.
Foddo offers several invisible watermarking methods. Some are best for lossless files, some are built for tougher edits, and some are still being tested against social platforms. The table shows where each method fits today.
| Method | Best for | Format save | Compression | Social platforms |
|---|---|---|---|---|
| LSBFragile | Lossless PNG, BMP, TIFF, and WebP carriers | Strong for unchanged lossless files | Weak | Not recommended |
| JPEG DCTFragile | JPEG-only compatibility | Medium | Weak to medium | Not recommended |
| TrustMarkPromising | Model-backed robust invisible watermarking | Good when models are available | Model-dependent | Not proven yet |
| Robust TransformPromising | Native token watermarking without external runtimes | Promising in controlled round-trips | Mild transforms promising; not guaranteed | Not proven yet |
| WAMPromising | Best candidate for social-platform survival | Promising in native ONNX tests | JPEG/resize promising; lossy WebP can be partial | Promising, not guaranteed |
Survival depends on image content, dimensions, output settings, and what a platform does to the file. The safest evidence comes from inspecting the exact downloaded copy.
