About us

Protect your videos.
Keep them yours.

WatermarkFlow is a browser-based video watermarking tool that burns moving, uncroppable watermarks into videos for creators publishing on YouTube, TikTok and Instagram. No uploads, no accounts, no waiting rooms — your footage never leaves your device.

What WatermarkFlow does

Text watermarks

Stamp your brand name, handle or copyright notice in 15 fonts with full control of color, size and opacity. The result is a crisp, readable mark that stays legible over any footage, so every repost carries your attribution with it.

Logo watermarks

Upload your own PNG or JPG logo and place it anywhere on frame. PNG transparency is preserved, so your mark blends into the video instead of sitting in an opaque box — ideal for client drafts and branded content.

Animated motion paths

Static watermarks get cropped out in seconds. WatermarkFlow animates your mark along Linear bounce, Parabolic, Circular or Random-jump paths — or drag it exactly where you want it. A moving mark survives crops, zooms and re-uploads.

Frame-accurate export

The offline renderer draws every single frame and encodes a clean WebM at full resolution with your original audio preserved. The output plays back with the same motion as your source — ready to upload anywhere.

What makes WatermarkFlow different

100% client-side — your footage never uploads

Tools like Kapwing and Canva upload your video to their servers before doing anything. WatermarkFlow decodes, watermarks and encodes entirely on your device, so unreleased client work and personal footage can never leak, and there is no upload wait on slow connections.

Free with no account, not freemium with a paywalled export

Most editors let you design for free and then charge — or stamp their own watermark — at export time. WatermarkFlow exports your full-resolution video free, with no sign-up, no trial clock and no paid tier standing between you and your file.

Frame-accurate offline rendering, zero dropped frames

Realtime screen-recorder-style exporters drop frames whenever your machine stutters, baking judder into the output. WatermarkFlow renders every frame deterministically — a 30-second clip at 30 fps always produces exactly 900 watermarked frames with motion identical to the source.

Native vertical and full-resolution output

Many web tools force landscape or downscale to 720p on free plans. WatermarkFlow preserves your source dimensions — 9:16 TikToks stay 9:16, 4K stays 4K — with your original audio track carried through untouched.

No queues, no rendering servers, no waiting rooms

Cloud editors queue your job behind other users at peak hours. WatermarkFlow starts rendering the instant you click export and runs at your machine's full speed — a typical 30-second clip finishes in a few minutes with a live progress estimate.

Frequently asked questions

Is my video uploaded anywhere?

No. WatermarkFlow has no backend for your footage: decoding, watermarking and encoding all happen locally in your browser tab. Closing the tab removes every trace.

What formats can I use?

Upload MP4, WebM or MOV (H.264, VP8 and VP9 decode best), add a PNG or JPG logo, and export a full-resolution WebM with your original audio preserved. Vertical videos keep their native 9:16 shape.

Why must the tab stay focused during export?

Your device does the rendering, and browsers throttle background tabs. Switching apps slows the render or corrupts frame timing — the progress bar shows a live ETA so you know how long to wait.

Why WebM instead of MP4?

WebM can be encoded royalty-free directly in the browser, which keeps the tool free and serverless. WebM plays everywhere modern — YouTube, Drive, TikTok — and uploads just like MP4.

Is WatermarkFlow really free?

Yes. There is no account, no trial and no paid tier, because there are no server costs to cover — your machine does all the work. The export you download carries only your watermark, never ours.

Which browser works best?

Chrome or Edge, which support the WebCodecs API behind the smooth offline export. Other modern browsers can still use the legacy realtime export with the same watermark features.

Ready to mark your work?

Free, unlimited, in your browser.
