Remove Runway watermarks and content tags
Runway exports carry a corner watermark plus embedded provenance metadata that identifies the clip as AI-generated. PurifyAI masks the logo region and strips the metadata, all inside your browser.
- Auto-detects the static logo, plus draggable multi-region masks
- Strips C2PA manifests, EXIF blocks and XMP provenance packets
- Nothing uploaded — processing happens in your browser tab
- Free to inspect any file, with no account required
Scan a file
No uploadPick a PNG or JPEG and the Runway scanner reads its bytes right here in your browser. Nothing is sent to a server — you can check your network tab. Free downloads: 5 of 5 left today, per browser.
Three steps, all on your device
No account required to try it.
- 1
Load your file
Drop an image or video into the browser. It is read into memory locally — there is no upload request, which you can confirm in your network tab.
- 2
Review what was found
The engine walks the actual byte structure and lists every metadata segment it finds: C2PA manifests, EXIF blocks, XMP packets and text chunks.
- 3
Export a clean copy
Metadata segments are dropped and the remaining bytes are rewritten. Pixels are untouched, so there is no re-encode and no quality loss.
What this tool handles
Video frame masking
Preset mask regions matched to where Runway places its watermark, with a draggable and resizable region for non-standard crops.
C2PA manifest removal
Content Credentials manifests are parsed out of the container rather than blindly overwritten, so the file stays valid.
Instant local processing
Typical images finish in well under a second because there is no round trip to a server.
Three reconstruction modes
Texture patch clone, smart border trim, or content gradient infill — pick whichever suits the footage.
Batch mode
Queue a whole folder of exports in the Batch Scrubber and strip metadata from all of them at once.
API access
Automate the same scrub from your render pipeline with the REST API on the Agency plan.
What gets removed, and what stays
Frequently asked
Anything else? Get in touch.
Does this remove the Runway watermark from the whole video?
Yes. The Studio re-encodes every frame with the mask applied and writes a real MP4 or WebM with audio preserved, so the mark is gone for the full clip — not just one frame. Because the re-encode runs in real time it takes roughly as long as the clip itself, and it does recompress the video, unlike lossless metadata scrubbing.
Will this reduce my image quality?
No. Metadata scrubbing rewrites the container around your image data — it drops the metadata segments and copies the pixel data through byte for byte. There is no decode and re-encode step, so the output is pixel-identical to the input. ICC colour profiles are deliberately preserved so colours do not shift.
Do my files get uploaded anywhere?
No. The scrubbing engine is JavaScript running in your own browser tab. There is no upload endpoint and no server-side processing queue, so your media never leaves your device. You can verify this by opening your browser network tab while you scan a file.
What is a C2PA manifest?
C2PA (Coalition for Content Provenance and Authenticity) is an industry standard for embedding a signed record of how a file was made. Generators like Runway, Sora and DALL-E attach one so downstream tools can tell the media was AI-generated. It lives in a dedicated segment of the file, which is what this tool removes.
Is it legal to remove watermarks and content credentials?
It depends entirely on the media and your intent. Removing marks from work you own or are licensed to edit is normally fine. Stripping provenance data to pass AI-generated media off as authentic in journalism, elections, legal evidence or identity documents is prohibited by our terms and may be unlawful where you are. You are responsible for how you use the output.
Is there a free tier?
Yes. You can scan and inspect files without an account at all. A free account adds a daily cleaning quota, and paid plans raise that quota and unlock batch processing and API access.
