How it works

At most 120 seconds per export. This is real-time recording, not frame-accurate cutting or lossless remuxing.

Frequently asked questions

Why did export stop when I changed tabs?

Recording stops on hidden tabs to avoid inaccurate output. Keep this tab visible until it finishes.

Are my files uploaded?

FileForge processes selected files on your device and has no file-upload API. Optional engines and models are downloaded from third parties; those requests expose connection information such as your IP address.

Will my work be saved automatically?

No. Files and editing results stay in this tab’s memory. Changing language preserves your work; reloading, closing the tab, or following a link to another page can clear it.

Just what you need.
