AI images come with watermarks you didn’t ask for

Every image from ChatGPT, Gemini, Sora and others ships with two kinds of marks: a visible watermark printed over the picture, and invisible provenance metadata baked into the file. Zilly removes both — cleanly, locally, and in one pass.

Visible watermarks

“Generated by AI” badges and logos that spoil the image. Zilly’s LaMa inpainting rebuilds the pixels underneath instead of blurring them.

Hidden metadata

C2PA content credentials, EXIF, XMP and IPTC that reveal how the image was made. Zilly strips them automatically on every export.

Everything you need to clean up AI images

A focused macOS app that does one job extremely well — so you stop paying per-image tools and subscriptions.

Removes visible AI watermarks

Inpainting erases logos, “Generated by AI” badges and caption text so the image looks untouched — the pixels are rebuilt, not blurred.

Strips hidden metadata

Removes C2PA provenance, EXIF, XMP and IPTC — including OpenAI’s content credentials — automatically on export.

Batch mode

Clean a whole folder in one pass. Each image is processed one at a time, so memory stays flat even with large sets.

100% on-device

Runs locally with a bundled LaMa Core ML model. Your images never leave your Mac — no uploads, no account, no cloud.

Precise mask controls

Paint, ellipse, rectangle and lasso tools with zoom, pan and full undo/redo. Auto-detect suggests watermark regions for you.

Fast, flexible export

Export PNG, JPEG or HEIC with quality control. Metadata is scrubbed on every write, and originals are never modified.

Remove a watermark in three steps

No uploads, no waiting on a server. It takes seconds.

  1. 1

    Open your image

    Drag in a single image or a whole folder. Zilly scans it for visible watermarks and provenance metadata.

  2. 2

    Mark the watermark

    Auto-detect suggests regions, or paint over the logo with the brush. Fine-tune with zoom, undo and redo.

  3. 3

    Remove & export

    Click Remove. The regions are rebuilt on-device and exported with all metadata stripped — in seconds.

Works with every major AI image generator

If it produces a raster image, Zilly can clean it — visible watermark, metadata, or both.

Metadata removal

Strip C2PA, EXIF, XMP and IPTC automatically

Modern AI images carry provenance data that says how they were made. Zilly removes OpenAI’s C2PA content credentials, EXIF, XMP and IPTC from PNG, JPEG, HEIC and TIFF files — and re-checks the file after writing so nothing is left behind.

  • C2PA provenance manifests (PNG caBX, JPEG APP11)
  • EXIF camera and software tags
  • XMP and IPTC descriptive fields
  • Automatic scrub on every export

Questions, answered

What is an AI watermark remover?

An AI watermark remover is a tool that takes watermarks off AI-generated images. Zilly removes two kinds of watermark: visible ones (logos, “Generated by AI” badges and caption text) using on-device inpainting, and embedded provenance metadata (C2PA, EXIF, XMP and IPTC) which it strips on export.

Does Zilly remove ChatGPT and Gemini watermarks?

Zilly removes the visible watermark text and badge that apps like ChatGPT (DALL·E), Google Gemini and Sora add to generated images, and it strips their embedded C2PA metadata. It works on any raster image, so it also handles Midjourney, Stable Diffusion, Firefly, Flux, Ideogram and more.

Can Zilly remove the SynthID watermark?

Not reliably. SynthID and similar systems embed an invisible pattern directly into the pixels, and there is no public detector to verify removal. Zilly includes an optional best-effort “wash” that lowers the odds the watermark can be read back, but we do not claim it removes SynthID — visible watermarks and metadata are what Zilly removes.

Do my images leave my computer?

No. The app processes everything locally on your Mac using a bundled LaMa Core ML model. There are no uploads, no accounts and no cloud processing. You can even use it fully offline.

What macOS and hardware do I need?

Zilly runs on any Apple silicon Mac (M1 or newer) running macOS 15 Sequoia or later. It is a native app, not a web tool.
