The app handles supported visible marks with local AI inpainting. Results depend on the surrounding visual detail; always review exports.

How it works
Import images
Drag files in or use the import button. Output defaults to Downloads unless you change it.
Identify and review
Let the app detect likely marks, then review the selection before clearing.
Clear and save
Run local AI inpainting and save the clean result to your selected folder.
Best for media you own or are authorized to edit. Complex text or subjects under a mark may need manual review.
Video watermark removal
Use frame thumbnails to choose exactly when and where a watermark appears. Small, precise ROI selections preserve speed and quality.

Import and inspect
Import a video, scrub the timeline, and click a thumbnail to preview that second.
Select only the needed areas
Use up to four adjustable boxes per frame. Tick a box to confirm it. Tick the same box on another thumbnail to copy the latest confirmed selection.
Fill ROI by time segment
The app processes only checked frames and each selected ROI separately, then composites it back into the original video.
Video inpainting is computationally intensive. Watermarks that cover faces, fast motion, or large areas can require more time and may need review.
Real local performance
Measured on a MacBook Air M4 with 32 GB unified memory, using a 10-second 1080p AI video.

Use the smallest practical ROI for the best speed.
FP16 is the default speed-first mode; choose FP32 when you prefer quality over time.
Video duration, resolution, selected seconds, and selected areas all affect completion time.
Private by design
Your images and videos are processed locally; the app does not upload your media.
Internet is only used for optional referral validation and product updates, never to process media.
Referral protection uses a one-way device fingerprint hash, not your raw hardware identifier.
Free to use. No paid tier.
Watermark Factory has no subscription and no feature paywall.
Start with 100 combined image and video uses.
Each successful invited friend earns one additional use.
Invite three successful friends to unlock unlimited use permanently.
Invite rules
- One invite code per Mac, protected by a one-way device hash.
- An invite counts after the referred user completes their first export.
- Self-referrals and repeat activations on the same Mac do not count.
- You can enter a valid invitation code once. Invalid codes simply do not activate an invite.
Questions
Does it upload my media?
No. AI processing runs locally on your Mac.
Is it really free?
Yes. There is no paid tier. You start with 100 uses and can unlock unlimited use by successfully inviting three friends.
Why is video processing slower?
Video restoration fills selected regions across frames, so time depends on resolution, selected duration, number of areas, and inference mode.
Will every watermark disappear perfectly?
Results depend on the content behind the mark. Review your export, especially with faces, text, fast motion, or large watermarks.
What content can I process?
Only process media you own or have permission to edit. Respect platform terms and the rights of creators.
