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.

Visible watermark removal that actually looks clean

Zilly uses LaMa, a state-of-the-art inpainting model, to rebuild the pixels under a watermark. Instead of smudging or blurring the logo, it reconstructs the background so the result looks like the mark was never there.

  • Erases “Generated by AI” badges, corner logos and caption text
  • Handles complex backgrounds — gradients, textures and detail
  • Runs the full model locally on Apple silicon in about 3 seconds
  • A fast built-in fill is used automatically if you want a quicker pass

Metadata removal for C2PA, EXIF, XMP and IPTC

Provenance metadata is the invisible watermark. Zilly reads the file at the byte level and removes C2PA content credentials (including OpenAI’s), EXIF, XMP and IPTC, then verifies the written file carries none of them.

  • Removes C2PA manifests (PNG caBX chunk, JPEG APP11 segment)
  • Clears EXIF camera/software tags and GPS-style fields
  • Strips XMP and IPTC descriptive metadata
  • Scrubs every exported file automatically — no extra clicks

Batch processing that stays fast and stable

Point Zilly at a folder and walk away. It processes images one at a time so memory stays flat, reports progress as it goes, and writes clean copies alongside your originals — never overwriting them.

  • Clean entire folders in a single run
  • Streaming, cancellable queue with live progress
  • Outputs saved as name-clean.png next to the original
  • Per-image results you can review at the end

Private by design — your images never leave your Mac

There is no cloud service behind Zilly. Detection, inpainting, metadata stripping and export all run on your machine, so nothing is uploaded and you can work fully offline.

  • No account, no sign-in, no uploads
  • Works offline with a bundled model
  • No tracking inside the app
  • Your originals are never modified

  • Brush, ellipse, rectangle and lasso selection
  • Zoom, pan and cursor-size feedback
