ONE FILE. MORE POSSIBILITIES.v1.1
Reduce video size
Export lower-resolution WebM. A smaller file is not guaranteed.
How it works
Open a video
Select a short interval and smaller output width
Record WebM and compare the actual size
Supported formats
MP4 / WebM / MOV → WebM — Input decoding and output encoding depend on browser support.
What this tool does
Reduces output dimensions and uses a resolution-based recording bitrate.
Before you export
No target-size guarantee. Export is WebM, not MP4, and a small original can become larger.
Frequently asked questions
How can I make the output smaller?
Reduce the width or interval length, then inspect the result. More compression can remove fine detail.
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.
