Clean Claude watermark signals from text and files locally.

Paste text, drop supported files, remove hidden Unicode markers, and strip image metadata without sending content to a server. Built for cleanup work you are allowed to perform.

Signal scanner

Designed around the signals hidden watermark tools usually inspect.

ClaudeWatermarkRemove.io scans text for invisible Unicode, spacing anomalies, and common generated-content footers. File mode handles text files, SVG metadata blocks, and raster image metadata through browser-safe cleanup steps.

Cleanup coverage

One workspace for text, SVG, and image metadata cleanup.

The tool follows the same local-first shape as the reference approach while keeping deployment simple enough for a static website.

Paste text

Remove zero-width characters, bidi controls, Unicode tag characters, variation selectors, soft hyphens, and unusual spaces.

TXTMarkdownJSON

Clean images

Re-encode browser-decodable images to PNG, JPG, or WebP so metadata and provenance chunks are removed from the new file.

PNGJPGWebP

Process SVG and code files

Clean hidden characters in text-based files and remove SVG metadata blocks and comments when the option is enabled.

Workflow

Paste, inspect, clean, and download in one browser session.

The first screen is the actual tool. It gives users visible counts before exporting a cleaned copy.

01Input

Paste or drop files

Start with text, SVG, common code files, or supported image formats.

02Review

Inspect detected signals

See hidden Unicode counts for text and choose image output settings for metadata stripping.

03Export

Download clean output

Copy cleaned text or download new files created locally by the browser.

Local-first processing

No upload queue and no remote file storage.

Text transforms happen in memory. Images are decoded by the browser and redrawn to Canvas. Downloads are created from local Blob URLs and source files are not rewritten.

Files stay on the device

The app does not need an API key, account, or server-side processor for supported formats.

Visible scan results

Text mode shows the exact categories that were detected before you copy or download.

Fresh output files

Clean downloads are new files. Your original input remains untouched.

Scope

Useful for cleanup, privacy review, and file hygiene.

The site removes common client-visible signals, but it does not promise universal detector bypass.

Works well for

  • Cleaning hidden Unicode from generated drafts you own
  • Normalizing pasted text before publishing or archiving
  • Removing image metadata from local PNG, JPG, and WebP exports
  • Cleaning SVG metadata and comments before web use

Limitations

  • No guarantee against every proprietary detector or model fingerprint
  • Image cleanup re-encodes pixels, so JPG and WebP outputs may be lossy
  • Unsupported formats such as PDF and DOCX are not rewritten in this static version
  • Use only on content you own or have permission to edit
FAQ

What to know before cleaning watermark signals.

Does this upload my files?

No. Text cleanup, SVG cleanup, and image re-encoding run inside your browser. The selected files are opened as local object URLs and clean outputs are generated locally.

What Claude watermark signals can it remove?

It removes common invisible Unicode markers such as zero-width characters, bidi controls, variation selectors, tag characters, soft hyphens, and unusual spacing.

Can it strip metadata from images?

Yes for supported browser-decodable raster images. The tool redraws the image to Canvas and exports a new PNG, JPG, or WebP file, which strips EXIF, XMP, C2PA, and most ancillary metadata.

Does it guarantee every detector will stop flagging content?

No. It removes common hidden characters and file metadata, but it cannot guarantee results against every proprietary detector, model fingerprint, or watermarking system.

Which files are supported?

Text, Markdown, JSON, HTML, CSS, JavaScript, TypeScript, YAML, SVG, PNG, JPG, WebP, AVIF, GIF, and BMP are supported in the browser.

Can I use it for any content?

Use it only for content you own or have permission to edit. The tool is intended for cleanup, privacy review, and file hygiene.

Start with a local cleanup pass.

Use ClaudeWatermarkRemove.io to inspect text and file signals before you publish, archive, or hand off content.
