Browser-based animation, offline and private: how it works

Many online video tools require you to upload your images to a server. If you work with client photos, company materials or unreleased content, that is a problem. Editor de Vídeo Online takes a different route: it runs inside your browser. Here is how that works, what is saved, when the internet is used and why it is a genuine offline animation tool.

One file, running in the browser

Editor de Vídeo Online is a web app contained in a single HTML file. You open it in Google Chrome or Microsoft Edge, and all processing — cutouts, animation, video recording — happens on your computer, using the browser's own capabilities.

That brings three advantages:

1. Privacy: your images do not need to leave your machine.
2. Works offline: once open, it does not depend on a connection.
3. No installation: no admin permissions or heavy software required.

When the internet is used

There is one clear exception: the Remove with AI option in the Paper effect. The first time you use it, the browser downloads the AI model. After that, it stays stored in the browser and can be reused without downloading again.

Every other cutout option — Plain background, Auto detect, Lasso, Quick selection and the brushes — works offline. See the comparison in how to remove a photo background.

What is saved and where

Editor de Vídeo Online saves your work in the browser itself as you go:

• Image, mode and settings.
• Style and backgrounds (including images uploaded as backgrounds).
• Cutouts, splits, merges and each element's animations.
• The chosen hand.
• The imported elements library.
• The Studio history and timeline.
• Which left-column sections were open or closed.

When you reload or reopen, everything comes back and the animation is regenerated.

Security and backup best practices

• Download your final videos: the recorded MP4 goes to your downloads folder. Keep it somewhere safe.
• Keep your original images: the browser is not a backup.
• Be careful when clearing browsing data: deleting "site data" can delete saved work.
• Use the same browser to continue a project.
• On shared computers, click Reset when you finish.

Who this matters for

Performance: your computer does the work

Since everything runs locally, performance depends on your computer. Recording is real-time, so close heavy programs and keep the tab visible. More tips in requirements and performance for recording video in the browser.

Frequently asked questions

Does Editor de Vídeo Online upload my photos to a server?

Image and video processing happens in your browser. The only connection needed is downloading the AI model the first time you use "Remove with AI".

Can I use Editor de Vídeo Online completely offline?

Yes, once it is open. If you want "Remove with AI" offline, use it once with internet first so the model is stored.

How do I move my work to another computer?

Saved work lives in the browser. To continue on another machine, bring the original images and recorded videos (import them into the Studio with Import video).

Conclusion

Running in the browser is not just convenient: it is a privacy choice. Your images stay with you, work is saved automatically and the internet only comes in when you ask for AI. Open Editor de Vídeo Online and work with peace of mind.
