SynthID Remover & Detector — Images and Video
One free tool to detect and remove Google's SynthID watermark from both images and video — Gemini, Nano Banana, and Imagen stills, and Veo and Gemini video clips. Switch between Image and Video above, drop your file, and it disrupts the invisible SynthID signal, clears the visible Gemini sparkle logo, and strips C2PA provenance and metadata in one pass. No sign-up, no account, no watermark of our own added.
SynthID is the watermark most tools can't touch. It isn't metadata — it's a pattern Google DeepMind embeds in the frequency layers of the pixels (for images) and across the frames (for video), engineered to survive re-saving, resizing, cropping, screenshotting, recompression, and transcoding. That's exactly why an ordinary EXIF or metadata stripper leaves it fully intact, and why removing it needs pixel- and frame-level processing rather than a container edit.
This is the single canonical SynthID hub: detector and remover, image and video, every Google AI source in one place. Below we explain how SynthID actually works, what removal can and can't do, and how to verify your result — so you know exactly what you're getting before you download.
Can SynthID be removed? How the watermark works
SynthID, from Google DeepMind, marks AI media by embedding an imperceptible pattern into the frequency layers of the image — the same domain a JPEG compressor works in — or across every frame of a video, rather than writing a tag into the file header. Because the signal lives in the content itself, it persists through the everyday edits that wipe normal metadata: cropping, resizing, format conversion, screenshots, moderate compression, and re-encoding all leave it readable by Google's SynthID Detector.
That resilience is why the real question isn't "is there a SynthID tag to delete" but "can the embedded signal be disrupted." A SynthID remover works by applying controlled, targeted adjustments to the pixel or frame values in those frequency bands to break up the watermark pattern, while keeping the visible media as close to the original as possible. Effectiveness depends on the file — resolution, how heavily it was compressed, and the specific SynthID version all matter — so the honest framing is strong signal disruption, not a guaranteed byte-perfect erase.
SynthID is also usually layered with other marks. Google AI exports frequently carry the visible Gemini sparkle logo painted into a corner or burned into frames, C2PA / Content Credentials provenance records, and standard EXIF and container metadata. Each is a different layer needing different handling — a metadata stripper misses SynthID, and a SynthID pass alone leaves the visible badge — which is why one dedicated workflow that clears all of them matters.
This tool detects and removes every supported layer together, for both media types: the SynthID signal from the pixels or frames, the visible sparkle logo, and the C2PA and file metadata — across Gemini, Nano Banana, Imagen, Veo, and other SynthID-marked media.
To inspect files before cleaning, use the SynthID watermark detector section on this page — the same scanning logic when you only need an audit.
What the detector checks
Detection and removal share the same scan. Before anything is stripped, each file is inspected so you know exactly which exports still carry watermark signals — re-saved copies, screenshots, and converted files do not always behave the same as direct downloads.
- SynthID invisible watermarks — Google DeepMind's frequency-domain fingerprinting in images (Gemini, Gemini 3, Nano Banana, Imagen) and per-frame in video (Veo, Gemini video)
- Visible Gemini sparkle logo painted into image corners or burned into video frames
- C2PA / Content Credentials provenance records where present alongside SynthID
- EXIF, IPTC, and container tags in PNG, JPEG, and WebP images
- Container and encoder metadata in MP4, WebM, and MOV video
Flagged files are reported clearly; clean files are labeled so you can skip unnecessary work. Audit first, or go straight to removal — both paths use the same scanning logic.
Understanding SynthID watermark signals
SynthID is Google DeepMind's invisible watermarking approach for AI media. Unlike metadata, it embeds a pattern in the pixel or frame data itself, built to survive resizing, cropping, and recompression — which is why ordinary metadata strippers do nothing to it.
Google SynthID-marked AI images and video may combine SynthID with the visible Gemini sparkle logo and standard container metadata, and the exact mix varies by export path — chat downloads, API responses, and studio exports do not always match.
This workflow removes all supported layers together: the visible sparkle logo, SynthID invisible watermarks, and C2PA container metadata, in a single pass.

How to remove a SynthID watermark
The whole flow takes under a minute for most files — no account, no sign-up, and no watermark of our own added to the output.
Step 1: Choose image or video
Use the toggle at the top of the tool, then drag and drop your file — JPEG, PNG, or WebP for images; MP4, WebM, or MOV for video. Batches are supported for images.
Step 2: Review what's detected
SynthID, the sparkle logo, C2PA, and metadata are reported per file so you can see exactly what each one carries before anything changes.
Step 3: Remove every layer
Run the removal: the SynthID signal is disrupted, the visible sparkle logo is cleared, and C2PA and metadata are stripped, while the media stays as close to the original as possible.
Step 4: Verify and download
Compare against your original, re-check the signal, and download the clean copy. Google's SynthID Detector should no longer return a confident match.
Supported formats
This SynthID watermark remover handles JPEG, PNG, WebP, MP4, WebM, MOV — the formats most common for Google SynthID-marked AI images and video exports. Output matches the input format, so files slot straight back into your workflow.

Batch and library cleanup
Clear mixed folders of SynthID-marked images at once, and clean video clips one by one.
Limitations to know
- SynthID removal is signal disruption, not a guaranteed byte-perfect erase. Results depend on the file — high-resolution, lightly compressed images and clips clean most reliably; heavily compressed or very small files are harder, and coverage varies by SynthID version.
- The process targets the SynthID signal while keeping the visible media as close to the original as possible. At the extreme, disrupting a stubborn signal can trade a small amount of fidelity — always keep your original and compare.
- Disrupting SynthID only affects SynthID detection. It does not defeat statistical AI classifiers, forensic analysis, or other detectors that read the media's own characteristics rather than the watermark.
- Video is processed one clip at a time and loads a one-time in-browser engine on first use; large clips take longer than images.
- Respect Google's terms and any AI-disclosure rules when redistributing media.
One page to detect and remove
SynthID Image Watermark Remover & Detector
This page covers the complete SynthID image watermark workflow: check a file for supported signals, review what was found, and remove the supported markers from a copy — one place for detection and removal instead of separate tools.
Also covers: SynthID remover · SynthID detector · SynthID image watermark remover · SynthID video watermark remover · remove SynthID watermark.
How to detect a SynthID watermark
The checker inspects each file for C2PA Content Credentials, SynthID invisible watermarks, and related provenance metadata, and reports exactly what each image carries before anything is changed.
- Add the image file to the tool.
- Run the detector and review each supported signal it reports.
- Keep the original for comparison before making any changes.
How to remove a SynthID watermark
The remover produces a cleaned copy with the visible logo or badge cleared and the C2PA, SynthID, and supported metadata markers stripped — pixels, dimensions, and transparency are otherwise preserved exactly. We support Gemini Sparkle Logo watermark removal on supported Google exports.
- Switch to Remover after checking the source.
- Process a copy and review the cleaned result.
- Download or copy the result, then verify it in its destination.
- Supported input
- Supported image files such as PNG, JPEG, and WebP.
- Signals checked
- SynthID invisible watermarks in images and video, the visible Gemini sparkle logo, C2PA provenance, and EXIF/container metadata across Google AI exports.
- Private workflow
- Files are never published or shared, and no account is needed. Detection, cleaning, and download happen in one place. Keep an untouched original until you have verified the result.
Detection and removal limits
A clean result means the tool did not find the signals it supports; it is not proof that no watermark of any kind exists. Deep proprietary SynthID or pixel-level patterns outside supported paths may not be fully affected. Always respect ownership, disclosure, platform, and licensing requirements.

Frequently asked questions
Can SynthID actually be removed?
SynthID can be disrupted so Google's detector no longer reads a reliable watermark, but it is not a metadata tag you simply delete. The signal lives in the frequency layers of the pixels or frames, so a SynthID remover works by carefully altering those values to break up the pattern. How completely it clears depends on the file — resolution, compression, and the SynthID version all matter — so treat it as strong signal disruption rather than a guaranteed byte-perfect erase.
Does this remove SynthID from both images and video?
Yes. Use the Image / Video toggle at the top of the tool. Images (Gemini, Nano Banana, Imagen) are processed in your browser in batches; video (Veo, Gemini video) is processed one clip at a time with an in-browser engine. Both disrupt the SynthID signal and clear the sparkle logo and C2PA metadata.
Why can't a normal metadata remover strip SynthID?
SynthID isn't metadata. EXIF, IPTC, and C2PA live in the file's container and come off with a container edit; SynthID is woven into the image or frame content itself and is designed to survive re-saving, resizing, cropping, screenshots, compression, and transcoding — the very operations that clear metadata. Removing it requires pixel- and frame-level processing, which this tool applies.
Does SynthID survive screenshots, cropping, compression, or re-encoding?
Yes — that's the point of it. Google built SynthID to persist through screenshots, cropping, resizing, format conversion, moderate compression, and video re-encoding, so those tricks won't remove it. You need a tool that targets the embedded signal directly.
Does removing SynthID reduce quality?
The process is designed to keep the visible media as close to the original as possible, and for most high-resolution, lightly compressed files the change is imperceptible. Because SynthID sits in the same frequency domain a compressor uses, aggressively clearing a stubborn signal can trade a small amount of fidelity at the extreme — so keep your original and compare before publishing.
Is there a SynthID detector on this page?
Yes — the tool reports whether a supported SynthID signal, the sparkle logo, and C2PA provenance are present before and after cleaning, for both images and video. Google's own SynthID Detector confirms Google-marked media; after disruption it should no longer return a confident watermark match.
How do I remove SynthID from a Gemini, Nano Banana, or Veo file?
Pick Image or Video, then drop the file. Gemini, Gemini 3, Nano Banana, and Imagen images and Veo and Gemini video all use SynthID, so the same workflow covers every Google AI source — the tool detects the signal, the sparkle logo, and any C2PA metadata and removes all supported layers in one pass.
What's the difference between SynthID and C2PA?
C2PA (Content Credentials) is signed provenance metadata stored in the file container — a label you can strip. SynthID is an invisible signal embedded in the pixels or frames, meant to survive when the metadata is gone. Google AI files often carry both, which is why this tool handles them together rather than assuming one covers the other.
Will platforms still detect my file as AI after removal?
Disrupting SynthID and stripping C2PA stops signal- and provenance-based detection like Google's SynthID Detector and Content Credentials Verify. Statistical classifiers and forensic analysis read the media's own characteristics and are separate technology, so a cleaned file is not a guarantee against every detector.
Is it legal to remove SynthID?
Cleaning media you created or have rights to is generally lawful, but several jurisdictions and platforms require disclosure of AI-generated content, and Google's terms may set their own rules. You are responsible for how cleaned files are used — disclose AI origin when required.
Is this SynthID remover and detector free?
Yes. Detection and removal for both images and video are free, no account or sign-up is required, and no watermark of our own is added to your files.
Can I check files before removing watermarks?
Yes. Use the detector section on this page to audit images first — it reports every supported signal per file, so you clean only what needs cleaning.
