How do I remove the Gemini watermark from an image?

Drop a Gemini, Imagen, or Nano Banana export on Unmark. Instant cleans one still in your browser with no account — PNG, JPG, or WebP, original resolution, no Unmark logo on the download. Use the drop zone on the homepage or on the image guide. Cloud is the next step when you want Library history, a folder of stills, or the Chrome extension to clean as you generate on Gemini or Google Flow. Instant will not clean an MP4; for video, drop the clip so Cloud can walk every frame. If Auto misses an odd placement, run the original export in Cloud and inspect the Library preview before you download.

How do I remove the Gemini watermark from a video?

Export the original MP4, MOV, or WebM from Gemini, Veo, or Google Flow — not a screen recording or a chat-app recompress. Drop the clip on Unmark (the homepage or a video guide). Cloud finds the sparkle on every frame and saves the clean file to Library. Sign in only if Unmark asks so the job can be stored. You can close the tab; turn on email notify if you want a ping when it is ready. New accounts include credits to try a short clip. Limits are listed on the upload card (short videos, up to 1080p, within the file-size cap).

Can Unmark remove image backgrounds?

Yes. Open Background removal under Tools, drop a PNG, JPG, or WebP, and download a transparent cutout for portraits, products, and AI stills. Sign in when Unmark asks so the PNG can save to Library. If the still still shows a Gemini sparkle, clean it with Instant or Cloud first, then cut out the cleaned file so the logo is not left on the subject. Hair, glasses, and product edges are the usual stress tests — preview the checkerboard before you download. Unmark does not relight the subject or invent a new backdrop; pair the PNG with your own layout.

Does this work with Google Flow and Veo videos?

Yes. Unmark removes the visible Gemini and Veo sparkle from video exports out of Google Flow, Veo, and Gemini. Drop the original clip; Cloud keeps it in Library until you download. Stills from the same Flow board can use free Instant. You do not need a separate product for Flow vs Gemini — the sparkle is the same family of mark. Screen-recording the Flow player captures UI chrome Unmark is not meant to erase. For a stack of Flow stills, use bulk Cloud or the Chrome extension instead of treating every asset as video.

What is the Gemini sparkle / stamp on images?

Google Gemini adds a small four-point sparkle, usually in a corner of AI-generated images and video frames. It is burned into the export — there is no Gemini setting that turns it off. Unmark is built for that visible mark, not for channel logos, captions, or stamps from other generators. The same sparkle family appears on Imagen, Nano Banana, Veo, and Google Flow exports. Cropping the corner is a poor substitute: you lose composition, and a tiled or inset sparkle can remain. Instant targets stills; Cloud targets video and saved jobs.

Can I remove a Gemini watermark for free?

Yes. Instant mode cleans a single image in your browser with no sign-in, original resolution, and no Unmark logo. That is the free Gemini watermark remover. Cloud features — video, Library, bulk, background cutouts, and the Chrome extension — use credits. New accounts get free signup credits so you can try a short clip or a cutout before you buy a pack. If you only needed one portrait for a slide, Instant is the whole product. If you ship a Reels calendar or client ads, Cloud is the part that keeps files in one place.

What's the difference between Instant and Cloud?

Instant is free in your browser for one still: drop a Gemini image, download the PNG, no account. Cloud saves to Library and unlocks video watermark removal, background cutouts, bulk stills, and the Chrome extension. Use Instant when you have a single PNG and a deadline. Use Cloud when the sparkle is on every frame of an MP4, when you need yesterday’s file again, or when you generate on Gemini or Flow all day. Both remove the same visible sparkle; they differ in where the file lives and which media types they cover.

Does Unmark work on Gemini 16:9 and 9:16 exports?

Yes. Unmark is built for common Gemini landscape and portrait exports and keeps the original resolution when you download. Clean a 9:16 story still with Instant before you crop to 1:1 — cropping first can clip or move the sparkle. The same advice applies to Veo: clean the 9:16 or 16:9 clip, then crop in your editor. Square Gemini stills work too. Video still has to fit the homepage length, resolution, and size limits.

Is there a Chrome extension for Gemini watermark removal?

Yes. Unmark for Gemini works on Gemini and Google Flow in Chrome: queue prompts, remove the sparkle, and download cleaned images so you are not exporting one file at a time. Sign in on Unmark so results appear in Library. Video and background removal stay on the website. The extension is optional — Instant on the site is enough for a one-off still. Install from the Chrome Web Store listing linked on unmark.ink/extension.

Is removing the Gemini watermark legal?

Use Unmark on content you created or have rights to use. Google adds the visible sparkle to AI outputs you generate; many creators remove it before publishing client work, ads, or social posts. Follow platform rules and disclose AI content where required — removing the sparkle does not replace those rules. Unmark does not claim to erase every provenance signal a platform might add, and it is not a tool for stripping marks from other people’s work. If you are unsure about a commercial use, check the platform’s current AI-media policy and your client contract.

What happens to my video if I refresh the page?

With Unmark Cloud, the clip stays in your Library even if you refresh or close the tab. You do not need to babysit the browser. Open Library when you come back, preview, and download. Turn on email notify in account settings if you want a ping when the file is ready. Instant stills never leave the browser tab — if you close Instant before you download, run the image again. That is the main reason video uses Cloud instead of Instant.

Can I download a Gemini video without the watermark?

Yes. Export the original clip from Gemini, Veo, or Google Flow, drop it on Unmark Cloud, and download the cleaned MP4 from Library when it is ready. Start from Google’s file, not a TikTok or WhatsApp recompress. Unmark aims to keep resolution, frame rate, and audio. A screenshot of one frame is not a video download — use Instant for that still, and this path for the MP4. New accounts include credits to try a short clip.

Does Gemini Advanced remove the watermark for me?

No. Google does not offer a setting to turn off the visible sparkle on Gemini, Veo, Imagen, or Nano Banana exports, including higher-tier Gemini plans. Unmark removes the sparkle after you download the file. Instant covers a single still in the browser; Cloud covers video and Library. If a Google product later adds an official unmarked export, you would not need Unmark for that file — until then, cleanup happens on the export you already have.

Guide

Unmark MCP Server

By Unmark editorial · Updated 16 August 2026

Connect Unmark to AI assistants via the Model Context Protocol (MCP). Remove Gemini watermarks, strip backgrounds, and poll Cloud jobs — all using your Unmark credits and Library. This is the chat connector, not the free Instant drop zone and not the repo skill.

Server URL

Use this URL when adding a custom connector in Claude or other hosted MCP clients:

https://mcp.unmark.ink/mcp

Claude Connectors

Claude supports hosted MCP with OAuth — no API keys to paste. You sign in with the same Google account you use on unmark.ink.

Open Claude → Settings → Connectors → Add custom connector.
Name it Unmark and paste the MCP server URL (see below).
Sign in with Google when Claude prompts you — this links your Unmark account.
In chat, ask Claude to remove a watermark or background from a public image URL.

Example prompts

Hosted MCP cannot read files from Claude's upload sandbox. Always use a public image_url or an Unmark share link.

“Remove the watermark from https://www.unmark.ink/s/abc123 using Unmark”
“Remove the background from https://example.com/photo.png using Unmark”
“Clean the Gemini sparkle from this share link: https://www.unmark.ink/s/xyz789”

Tools

remove_watermark
Remove the Gemini sparkle watermark. Pass image_url (public HTTPS) or a unmark.ink share link.
remove_background
Remove the image background. Same URL rules as remove_watermark.
get_job_status
Check progress or fetch results for a Cloud job by job ID.

Image URLs & share links

Public HTTPS URLs — direct links to PNG/JPEG/WebP files work best.
Unmark share links — https://www.unmark.ink/s/<job-id> resolves automatically to your Cloud job image.
Not supported in hosted MCP — local file paths (e.g. Claude upload paths like /mnt/user-data/uploads/...) are only available in local stdio setups such as Cursor.

MCP vs Instant vs the agent skill

Instant is the no-account stills tool in the browser. Use it when you have one Gemini PNG and you want a download now. The agent skill is for Cursor, Claude Code, and Codex working on files already in a repo. MCP is for chat: you pass a public image URL or an Unmark share link, and Claude (or another client) calls Unmark Cloud.

Hosted MCP will not see a file you attached only inside Claude. Local stdio in Cursor can use env tokens and, in some setups, local paths — that is why the Cursor block below exists. If you only needed a sparkle off a still, skip this page and open Instant.

Cursor (local stdio)

For Cursor or other editors that run MCP as a local process, configure stdio transport and point at the unmark-mcp package in the repo. Local mode can use bearer tokens or session cookies for auth.

Install Python 3.11+ and clone the unmark-mcp package from the repo (see README).
Sign in on unmark.ink and copy your session cookie, or set UNMARK_BEARER_TOKEN for local dev.
Add the server to Cursor MCP settings (stdio transport).
Restart Cursor and invoke tools from the agent chat.

Example .cursor/mcp.json:

{
  "mcpServers": {
    "unmark": {
      "command": "python",
      "args": ["-m", "unmark_mcp.server"],
      "env": {
        "UNMARK_API_URL": "https://api.unmark.ink",
        "UNMARK_BEARER_TOKEN": "<your-token-if-using-static-auth>"
      }
    }
  }
}

Connect Claude to Unmark

Copy the MCP URL into Claude Connectors, sign in with Google, and start cleaning images from chat.

Common questions

Do I need a separate API key?

Not for Claude Connectors. Claude’s hosted MCP uses OAuth with the same Google account you use on Unmark — you sign in once when you add the connector. Local Cursor or other stdio setups can use a bearer token or a browser session cookie instead of OAuth. There is no second Unmark “MCP key” to buy. Cloud credits on your Unmark account are what the tools spend when they actually clean an image.

Why does Claude say it cannot read my upload?

Hosted MCP can only fetch public HTTPS image URLs or Unmark share links. Claude’s private upload paths (for example files under /mnt/user-data) are not visible to Unmark. Put the still on a public URL, share it from Library, or use the agent skill on a local file in Cursor. This is the most common setup miss — the connector is working; the image URL is not reachable.

Does MCP use Cloud credits?

Yes. remove_watermark, remove_background, and get_job_status call the same Cloud product as the website and the Chrome extension. Finished jobs show up in Library so you can download them in the browser too. Instant in the browser does not use MCP and does not need a connector — it is the no-account stills path. Use MCP when you want Claude or another client to trigger cleanup from chat.

Can a coding agent clean files in my repo?

Yes — that is the agent skill, not hosted MCP. Install from https://www.unmark.ink/skills so Cursor, Claude Code, or Codex can clean local stills as part of a larger task. MCP stays the chat connector for public URLs. Pick skill for repo files, MCP for “clean this https link,” and Instant for a one-off drop in the browser.
