Frequently Asked Questions
Have questions about our cut tool? Find the answers below.
Q.Is my video processed locally?
Klipworm is designed for browser-based editing. Dedicated tools keep media in the current browser session, while full projects can also autosave locally.
Q.Can I trim vertical videos?
Yes. Klipworm supports vertical, square, and landscape canvas formats for social platforms.
Q.Will trimming reduce the quality of my output file?
No. Klipworm performs video operations directly on the browser container coordinates, meaning your frames remain crisp and sharp without server-side re-compression loss.
Q.How large of a file can I upload to trim?
Since Klipworm operates entirely inside your local browser session, there are no artificial file size upload ceilings. The only limit is your local hardware storage capability.
Q.Can I undo my trim cuts?
Yes. The editing timeline is completely non-destructive, meaning you can adjust the handles and restore trimmed segments at any point during your session.
Q.Can I trim the middle out of a video?
Yes. Use the split feature to divide the video into three segments, select the middle section on the timeline, and press delete to remove it.
Q.Is there any hidden subscription fee or watermark on the exported files?
Absolutely not. Klipworm is completely free to use. All of our browser-based video editing and export features—including high-definition rendering up to 4K—are watermark-free and have no hidden usage limits or recurring subscription costs.
Q.Does this tool require installing software or browser plugins?
No. Klipworm is a native, web-based tool. It runs entirely inside your active browser sandbox using web standards like WebGL and WebAssembly. You do not need to download, install, or configure any external applications or browser extensions.
Q.Can I continue editing my projects offline without an active internet connection?
Yes. Since all decoding, editing, and rendering engines operate directly on your computer's local hardware (CPU/GPU) within your browser session, you can adjust your timelines, edit parameters, and compile files even if you go completely offline.
