How to remove a watermark from a video
The best results come from a tight box and the right mode for the footage behind the mark. Here's the order that works.
- 01
Load a short clip with a fixed watermark
Drop an MP4, WebM or MOV file. It plays from your own device; nothing is uploaded. The tool works on marks that stay in one place for the whole clip, like a channel logo or a camcorder timestamp.
- 02
Snap the box to a corner, then tighten it
Pick Bottom Right, Bottom Left, Top Right or Top Left, then fine-tune position and size with the sliders. Width runs from 4% to 60% of the frame and height from 4% to 50%. Make the box only just larger than the mark: every extra pixel is a pixel you'll soften or cover.
- 03
Choose how to hide it
Smart Blur smears the mark into its surroundings, Border Fill paints the box with colours taken from its edges, and Solid Bar covers it with a colour you pick. The table below shows which to choose for which footage.
- 04
Scrub through the whole clip before exporting
Drag the timeline through bright scenes, dark scenes and fast motion. A box that looks perfect on one frame can stand out on another, especially with Border Fill.
- 05
Export in real time and keep the tab visible
Export plays the video once while recording the cleaned frames, so a 2-minute clip takes about 2 minutes. Keep the tab open and in view: browsers pause drawing in hidden tabs, which would freeze frames in the output.
Blur, fill or cover: picking a mode
A watermark burned into a video is part of every frame's pixels. There's no hidden layer to switch off, so the choice is really about what kind of patch will be least noticeable. All three modes are applied to every frame as the video plays.
| Mode | What it does | Works best on | Struggles with |
|---|---|---|---|
| Smart Blur | Shrinks the box area and stretches it back up, 6 to 40 strength | Busy, moving backgrounds where a soft smudge blends in | Large boxes; the blur becomes an obvious frosted patch |
| Border Fill | Blends the colours just outside the box across the inside, every frame | Static, evenly coloured areas such as sky, floor or a dark corner | Detailed or moving backgrounds; the fill can flicker |
| Solid Bar | Covers the box with one colour you choose | Letterbox bars, black borders and lower-third strips | Anything in the middle of the picture |
Here's what box size means in real pixels. The default box is 20% wide and 14% tall. On a 1920 × 1080 video that's 384 × 151 px, about 2.8% of the frame. With Smart Blur at strength 16, that 384 px wide area is shrunk to 48 px and stretched back, which is why the logo's shapes disappear. Halve the box to 10% × 7% and you're softening a quarter as much picture, so the patch is much harder to spot.
Where it helps
Timecodes burned into old camcorder footage
Bright date and time digits usually sit in a bottom corner over a dark or steady area. Border Fill tends to hide them better than blur, which would leave a glowing smudge.
Your own channel logo on an archived upload
If you've lost the clean master of a video you published with a corner logo, a tight Smart Blur box gets you a usable copy for a new edit or platform.
Notification pop-ups in a screen recording
A toast with a name or phone number that appeared during a fixed stretch of a screencast can be covered with a Solid Bar matched to the app's background colour.
Letterboxed footage with text in the black bars
Subtitles or credits placed in the black bars above or below the picture disappear cleanly under a black Solid Bar, with no visible patch at all.
What to expect from the export
Because everything runs in your browser, the export works differently from desktop software. The video is played once from start to finish, each frame is drawn to a canvas with your chosen mode applied, and the canvas is recorded at up to 30 frames per second. A 3-minute clip therefore takes about 3 minutes, and at roughly 3.5 Mbps it produces about 79 MB of video before audio.
- It's a re-encode. Every frame is compressed again, so fine detail and sharp text elsewhere in the picture may soften a little, most noticeably on 4K sources.
- 60 fps becomes 30 fps. Fast sports or gaming footage will look less smooth after export.
- Keep the tab in front. Switching tabs or minimising the window during export can freeze frames in the result.
- Keep your original. Check the exported file, including its sound, before deleting the source.
