Trim Video

Core access Supported local processing No Pixlane watermark

Choose start and end boundaries for a compatible MP4 or MOV. Fast mode can copy encoded samples between usable keyframes; Precise mode re-encodes nearer the selected boundaries. Review the result because codec and browser support vary.

Stream copy when compatible

Fast mode copies compatible encoded samples between usable keyframes instead of re-encoding them; boundaries and runtime vary by source, browser, and device.

Precise re-encode mode

Precise mode re-encodes near the selected in/out points when browser codec support is available; inspect the exported boundaries.

Scoped local processing

Demux, cut, and remux run on your device for supported inputs. Video contents are not uploaded for processing; site analytics and the assistant are separate.

Frequently asked questions

Does trimming reduce quality?

For compatible inputs in Fast mode, the tool copies existing encoded samples between usable keyframes instead of re-encoding them. Precise mode re-encodes the selected segment, so output quality can vary with encoder support and settings.

Why does the start time snap slightly?

Fast stream-copy cuts can begin only at available keyframes, so the requested start may be adjusted to a nearby keyframe. Use Precise mode when you need a re-encoded cut closer to the selected frame.

Is there a file size limit?

There is no single reliable browser-wide size limit. Processing uses memory on your device, so the practical limit depends on the file, browser, device memory, selected mode, and clip length.

What video formats can I trim?

Compatible MP4 or MOV inputs may use stream copy. Other supported container and codec combinations require browser decode and encode support and may be re-encoded; availability varies by browser and device.

Can I trim a video on my phone?

On compatible mobile browsers, availability depends on codec support and device memory.
