Add Watermark to Video Online Free - Text Watermark Tool

A Yes, the text watermark is applied to every frame of the video.

A The watermark uses a white font with a subtle shadow for maximum visibility on any background.

A Our 'no upload required' feature is a key privacy benefit. When you use our free online video watermark tool, your video files are processed directly in your web browser. This means your video never leaves your device and is not sent to our servers. You maintain complete control and privacy over your content, ensuring your sensitive videos remain secure while you add a custom text watermark.

A Our free online video watermark tool processes your video directly in your browser. This client-side processing aims to preserve your original video quality as much as possible, as it avoids re-encoding when applying the text watermark. The output video will retain its original resolution and generally a similar file size, ensuring your content protection doesn't come at the cost of visual fidelity or larger downloads.

A You can precisely position your text watermark using our intuitive drag-and-drop interface. Simply click and drag the watermark box to your desired spot on the video preview. We offer 9 predefined positions, including corners and the center, or you can place it anywhere in between.

A The preview shows the watermark overlaid on a single frame, but the final video applies it to every frame. Sometimes this can cause slight shifts in how the text blends with motion. For best results, set opacity between 70-80% and avoid placing the watermark near fast-moving content at the edges.

A No hard limit exists for video length. The tool processes everything client-side, so your browser's memory is the real constraint. A 10-minute 1080p video runs fine on most modern machines. For 4K footage longer than 5 minutes, you might notice slower performance. Stick to under 30 minutes for smooth results.

A Zero installation, no account, and nothing to download. Everything runs inside your browser using standard web technologies. Just open the page, pick your video file from your computer, and start watermarking in seconds. The tool works on Chrome, Firefox, Edge, and Safari. Even older laptops handle it fine. One gotcha: if your browser blocks local file access, check your privacy settings first.

A The white text with a subtle shadow handles contrast well across most backgrounds. But you might lose readability on pure white or very bright scenes. Our opacity slider goes from 10% to 100% — for mixed lighting videos, set it around 60-65%. That strikes a balance between visibility and not overwhelming bright sections. Test a short clip first before processing the whole video. One trick: place the watermark in the bottom-right corner since most online viewing players dim that area slightly.

A Nothing stays on our servers. Since the tool runs entirely in your browser, your original file never gets uploaded anywhere. The watermarked video gets rendered locally, then your browser triggers a download automatically. Once you close the tab, every trace of processing data disappears. Your source file stays untouched on your computer. Smart move: rename the output file right after downloading so you don't confuse it with the unmarked version later.
