How it works

Three steps, a few seconds, zero friction.

Drop your image

PNG, JPG or WebP. On the free tier it never leaves your browser.

We detect & strip

Unmarkr scans for AI provenance markers and removes them while keeping your pixels intact.

Everything you need to ship clean images

From a quick free clean to a production API — one engine, every watermark type.

Free

Visible logo removal

Reverse-alpha recovery lifts Gemini sparkles, Doubao/Jimeng text strips and Samsung marks — restoring true pixels, not blurry guesses.

Free

Provenance metadata

Surgically removes C2PA Content Credentials, EXIF/XMP, PNG text chunks and “Made with AI” labels.

Pro

Invisible watermarks

Diffusion regeneration removes SynthID, StableSignature and TreeRing marks while preserving structure.

Pro

Batch processing

Drop a whole folder and clean hundreds of images in one pass.

Pro

Developer API

A clean REST API with keys and usage-based billing — wire watermark removal into your own pipeline.

Always

Privacy by default

Free cleans run locally in your browser. API uploads are transient and auto-expire — never used for training.

Developer API

Watermark removal, one request away

Wire Unmarkr into your generation pipeline, CMS or batch job. Authenticate with a key, POST an image, get a clean one back. Usage-based billing means you only pay per image — and the same endpoint scales from visible logos to invisible SynthID removal.

• Synchronous for visible + metadata · async jobs for invisible
• Per-key rate limits & metered billing
• JS & Python SDKs (coming with the API launch)
