Processing and output
Transparent PNG images preserve the watermark shape. The video is re-encoded on export.
Does my video get uploaded?
No. Selected video, audio, subtitles and fonts are processed in this browser. They are not submitted to a video processing server.
What settings does Add Video Watermark offer?
Transparent PNG images preserve the watermark shape. The video is re-encoded on export.
Can I add a transparent logo watermark?
Yes. A PNG with a transparent background keeps its shape when placed over the video. A JPEG has no transparency and includes its rectangular background.
Is this tool a watermark remover?
No. It overlays your selected image and does not remove logos or reconstruct content hidden underneath an existing watermark.
Can I process large files on a phone?
Modern browsers are supported. Combined inputs are limited to 300 MB on desktop and 100 MB on phones or low-memory devices, with lower default output resolution. Merge up to 8 clips. Short clips work best; transitions, compression and conversion can take time.
