- clear browser support and file-size limits
- no FastTool application upload or account required
- output size and duration proof after export
- safe fallback message when the browser cannot encode video
REVIEWED OUTPUT EVIDENCE
Sample input, expected output, and safe-use boundary
This page is not a generic directory entry. It gives a concrete control input, an expected result, real browser limitations, and a not-for boundary before the visitor uses a real file.
Expected output
Exported WebM should contain only the selected section, play in the browser, and report a duration close to 4.5 seconds.
Proof checks
- Checks actual video preview and export path, not only a file picker.
- Selection duration, output type, and output bytes are visible after export.
- Warns when the browser cannot encode local video instead of pretending every device works.
When not to use it
Not for feature-length files, legal evidence, codec-preserving broadcast work, DRM media, or exact frame-accurate professional editing.
Privacy boundary: Standard processing is designed to happen in your browser tab. The page can still load normal site scripts such as consent, analytics, ads, and third-party libraries where needed, so do not use regulated or confidential media unless your own policy allows it.
COMMON QUESTIONS
Before you process a real file
How do I cut a video online?
Choose a local video, set the start and end time, preview the section, then export a trimmed WebM copy.
Does my video get uploaded?
The standard workflow uses your browser file APIs and does not upload the video to a FastTool application server.
Why is the output WebM?
Modern browsers expose reliable local recording through WebM. MP4 encoding support varies by browser.
What is the practical file limit?
Use short clips first. Large videos depend on your device memory and browser MediaRecorder support.
Methodology, sources, and limitations
FastTool media tools use standard browser APIs such as File, HTMLMediaElement, Canvas, Web Audio, MediaRecorder, and optional lazy-loaded open-source encoders. The site intentionally surfaces browser limits instead of claiming cloud-editor fidelity.
