How to Add an OnlyFans Watermark to Photos and Videos

What the OnlyFans and Fansly settings actually do

OnlyFans documents its watermark in two places. The help article How do I put a watermark on my content? calls it a free digital watermarking service, says it makes copying or unauthorised use harder, and tells creators to select Watermarks in Privacy and Safety settings and edit the custom text. The Transparency Center page on helping creators protect their copyright describes the mark as light digital text placed on top of a creator's content, and notes that Digital Rights Management protections can be switched on in the same section.

That matters because several guides ranking for this search state flatly that OnlyFans has no built-in watermark and that every mark must be added before upload. OnlyFans' own pages say otherwise, so treat them as the current position and recheck the menu after app updates, since settings screens get rearranged. The two features do different jobs: the watermark labels what viewers see, while DRM is aimed at piracy during playback and puts nothing visible on the frame.

Fansly's help article on keeping your content safe, dated 25 September 2025, lists watermarking for traceability and deterrence and says you manage it in the Creator Dashboard under Uploads. Its Creator Hub guide to a first post points to the same place and suggests setting it before you upload anything. The same help article tells creators who find stolen media to check the watermark and try to identify the user it is linked to, so Fansly treats its mark as a tracing aid rather than only a logo. Our Fansly posting guide covers the rest of the upload flow.

Neither platform documents the details a video creator needs: which media types carry the mark, where it sits in the frame, how large it is, or whether you can move it. Upload a short test clip, look at how the mark renders on a phone and on a desktop browser, and write down what you see before you rely on it for a full release.

When to burn your own mark into the file

A platform watermark exists only on that platform. The teaser you post on X or Reddit, the preview clip in your link page and anything you sell through a second site leaves your computer clean unless you mark it yourself. Burning a mark into the pixels also lets you choose the design, the position and the size, which neither setting appears to offer.

• Mark the export, never the master: finish your edit and colour, export a clean master file, store it privately, then make marked copies for each destination.
• Use a stage name or handle plus the platform address as the text, and never a legal name, a phone number, a suburb or anything else that links the persona to your offline life.
• Prefer tools that work on your own device. Lightroom Classic and FFmpeg run locally, and Watermarkly's video page says clips are processed in the browser with only saved templates uploaded to its servers.
• Read the privacy policy of any web or phone app before giving it intimate files, and check whether it keeps uploads, for how long, and where.
• Keep one consistent design across platforms so a copy found anywhere is recognisably yours, and store the template with your brand files.

Marked copies are also a reason to look at what else travels inside the file. A watermark does nothing about location or device details stored in the file itself, which our guide to removing metadata from photos and videos covers device by device.

The rows below compare documented features only, read from each vendor's own page on 2 October 2026. Prices are as each page shows them, in US dollars, and change often, so confirm before paying.

One inconsistency is worth knowing before you buy. Watermarkly's pricing page lists its web app for photos and PDF files, while its separate video watermark page offers video marking in the browser. Run a free test on one clip, accepting the extra logo, before paying for the format you actually need. Editing apps that add marks as part of a wider edit are compared in our guide to photo editing apps for creators.

Placement checklist: marks that survive a crop

FFmpeg's documentation includes a delogo filter that smooths over a logo inside a fixed rectangle you specify, which shows why a small mark parked in the same corner of every frame is the easiest kind to clean off. Placement does more for durability than font choice does.

• Overlap part of the subject or a detailed area, so cutting the mark out means cutting into the picture people want.
• Avoid the outer edges and corners on their own, because a simple crop to a new aspect ratio removes them.
• Keep the mark inside the area each destination actually shows: the vertical frame for short video, the square preview on profile grids, and the space clear of captions and buttons described in our Reels safe zone guide.
• Show it for the whole runtime of a video, not only in the opening or closing seconds, which are the first parts anyone trims.
• Consider a slow drift or a few positions across a set, so no single rectangle covers the mark on every frame or every image.
• Use semi-transparency with an outline or soft shadow, then check legibility on both the brightest and darkest scenes in the clip.
• Scale the mark to each file rather than using one fixed pixel size, which Lightroom Classic's Proportional setting and Watermarkly's autoscaling both handle.
• Tile a faint repeated pattern across high-value images if the design allows, accepting that it changes how the image looks.
• View a marked test file at phone size before a release, since a mark that reads on a monitor can vanish on a small screen.

Visible and invisible marks

A visible mark works on people: it tells a casual reposter the file has an owner and tells a new viewer where to find you. An invisible mark works on software: it hides an identifier in the image data, and only a matching reader can detect it. iWatermark+, for example, lists an invisible steganographic option for photos alongside its visible styles.

Content Credentials are a related but different tool. Adobe's Content Credentials overview describes them as an industry-standard metadata label recording who made a file and how. Adobe Research's note on the three pillars of provenance admits that platforms commonly strip that metadata, and explains that durable credentials add an invisible watermark, called TrustMark, so the record can be looked up again. Because credentials can carry a verified name and social accounts, check exactly what they will display before attaching them to work published under a stage name.

Invisible marks are evidence aids, not deterrents. Vendors make their own claims about what survives recompression, resizing or screen recording, so ask for their documentation and test with your own files before paying for a forensic service.

A batch workflow for video

FFmpeg is the most flexible free route for marking a folder of clips, and it runs entirely on your own computer. Make your mark once as a PNG with a transparent background, sized for your usual export resolution.

1. Put finished exports in one folder, the PNG beside them, and create an empty subfolder named marked for the output.
2. Run the single-file command below on one clip and watch the result before processing everything.
3. Swap in the drifting version if you want the mark to wander slowly around the frame instead of sitting still.
4. Run the loop version to apply the same settings to every clip in the folder.
5. Spot-check the first, middle and last file in the batch, including the audio, then upload only the copies in the marked folder.

One clip, with the mark half transparent and placed in the lower middle of the frame:

A drifting mark, which uses the overlay filter's per-frame position expressions:

Every MP4 in the folder, from a Mac, Linux or Git Bash terminal:

These commands copy the audio untouched and re-encode the picture with FFmpeg's defaults, so compare file size and quality with your usual export and adjust the encoder settings if needed. Keep the clean masters in storage you control; our cloud storage comparison for creators covers which services allow what, and the content backup workflow covers keeping restorable copies.

Limits of watermarking

A watermark proves nothing on its own and stops no one determined to copy you. It cannot prevent screen recording, it can be blurred, cropped or painted over, and a heavy mark can make paid work less pleasant to look at. A platform mark protects only what is viewed on that platform. The limitations of this page are also real: it compares a handful of tools on documented features, not tested performance, it reflects pages read on 2 October 2026, and both platforms can change their settings without notice. Watermarking supports copyright records but does not replace them; for a takedown, a dispute or a buyer who has shared custom work, keep your originals and dated exports and get advice from a qualified intellectual property lawyer where the stakes justify it.
