How to Trim a Video Online

You recorded a 10-minute video but only need the middle 45 seconds. Or a meeting recording has 5 minutes of dead air at the start. Trimming cuts a video down to exactly what you need — no complicated editing software required.

How to trim a video online

1. Upload your video — select the file you want to trim. The tool accepts MP4, WebM, MOV, AVI, and other common formats.
2. Set start and end times — drag the timeline handles or enter exact times. The video player previews your selection in real time.
3. Download the trimmed clip — choose your trimming mode and download the result.

Fast mode vs. precise mode

Fast mode (stream copy):

• Instant processing — no re-encoding
• Original quality preserved exactly
• Cut points may be off by 1-2 seconds (lands on nearest keyframe)
• Best for: removing large sections, rough cuts, quick extractions

Precise mode (re-encode):

• Takes longer (depends on video length and your device)
• Frame-accurate cut points — exactly where you set them
• Minimal quality difference at default settings
• Best for: clean cuts, clips for presentations, content that will be published

For most uses, fast mode is the right choice. Use precise mode only when the exact start and end frames matter.

Common trimming tasks

• Remove intro/outro — cut dead air, countdown screens, or branding from the start or end
• Extract a highlight — pull out the best moment from a longer recording
• Meet file size limits — a shorter video is smaller, helping you fit under upload limits
• Clean up recordings — remove mistakes, pauses, or irrelevant sections

Tips

• Preview before processing — use the "Set to current" buttons to mark trim points while watching the video. This is faster than typing timecodes manually.
• Trim before compressing — if you need both a shorter and smaller file, trim first, then compress. Compressing a shorter clip is faster and gives better results.
• Use fast mode by default — unless you specifically need frame-perfect cuts, fast mode saves significant processing time with no visible difference.
• Keep the original — trimming creates a new file, so your original video is safe. But it is good practice to verify the trimmed result before deleting the source.
