Video Trimmer Online

Trim the beginning and end of a video with clean, fast exports.

1. Add Your Video

Drag and drop a file or paste a video URL

Maximum file size: 500MB

2. Set Trim Points

Specify the start and end times for your trimmed video

Intro

Trimming is the fastest way to remove unwanted seconds from the beginning or end of a clip. VideoComposer lets you set clear start and end times and produce a clean output without desktop software. It is a simple tool that keeps the workflow focused on speed and accuracy.

The trimmer uses fast, keyframe-aligned cuts for efficiency. This is ideal for quick edits, but it can be off by a fraction of a second on some files. If you need frame-perfect precision, you can re-encode in your own workflow or request a precise mode in the future.

Every trim is an asynchronous job, so you can start the process and return once it is complete. For teams, the API offers the same trimming capability so you can automate edits at scale and keep results consistent.

Trimming is often the first step before conversion, watermarking, or merging. Shorter clips process faster and reduce the overall time needed for downstream jobs, which is especially helpful in CPU-based workflows.

If you handle recurring recordings, set consistent trim ranges to remove intros and outros across files. This keeps content standardized and saves manual time when publishing or sharing with teams.

How it works

  1. Upload a video or paste a direct URL.
  2. Set start and end timestamps in HH:MM:SS format.
  3. Submit the trim job and download the new clip when it finishes.

Use cases

  • Remove intros, outros, or dead air from clips.
  • Create short highlights for social or support updates.
  • Trim videos to meet length requirements for platforms.
  • Prepare shorter clips before converting to GIF.
  • Shorten recordings before sharing with clients or stakeholders.

Formats and limits

  • Inputs: MP4 and WebM in the current browser tool.
  • Output: MP4.
  • Cuts are keyframe-aligned for speed; exact frames may vary slightly.
  • Processing time depends on length; anonymous usage is rate limited.
  • If you need WebM output, trim first and then convert the clip.

After processing

When your video trimmer job completes, you will receive a downloadable output URL. You can save the result locally, share it with a teammate, or feed it into another tool such as the trimmer or converter. For repeatable workflows, use the API to store outputs in your own system and automate the next step.

Tips

  • If the cut is slightly early or late, move the timestamp a bit to match the nearest keyframe.
  • Trim before converting to GIF to keep results small and focused.
  • Use clear timestamps to avoid accidental zero-length clips.
  • Keep the original file in case you need a different cut later.
  • Automate repeated trims with the API to avoid manual work.
  • Trim first, then convert to keep output format consistent.

Deep dive

Start and end times accept HH:MM:SS formatting. If you only need seconds, you can still provide a full timestamp like 00:00:10 for clarity.

For recurring edits, keep a simple list of timestamps so you can trim multiple files consistently. This reduces manual error and speeds up review cycles.

If you need precise edits, run a short test trim first to confirm your timestamps before processing long recordings.

Workflow checklist

  • Confirm start and end times in HH:MM:SS format.
  • Trim before converting or merging to save time.
  • Expect small keyframe shifts on fast trims.
  • Automate recurring trims with the API.
  • Use the trimmer to shorten files before longer workflows.

FAQ

Can I trim without losing quality?

Trimming uses fast stream copy when possible, so quality is preserved. Because cuts align to keyframes, the exact frame may shift slightly in some files.

Why is the cut not frame-perfect?

Keyframe-aligned trimming is faster, but it can land a fraction of a second off. Re-encoding can provide frame-level precision if required.

Can I keep the original resolution?

Yes. The trimmer keeps the original resolution and codec settings where possible.

Does trimming change the audio?

Audio is preserved with the same segment as the video.

What formats can I trim?

The browser tool accepts MP4 and WebM. If you have other formats, convert them to MP4 or WebM first.

What are the limits for free users?

Anonymous usage is rate limited. Sign in for higher limits and more consistent throughput.

Can I trim videos programmatically via API?

Yes. The API provides the same trimming functionality with asynchronous jobs.

Trim videos with the API

For repeatable edits or large batches, the API lets you submit trim jobs with start and end times. Results are returned as output URLs you can store or deliver to users.

Combine trimming with conversion to standardize formats and clip lengths in one workflow.

Queue multiple trim jobs and track them asynchronously so your application remains responsive while processing runs in the background.

  • POST /video/trim with start and end timestamps
  • GET /jobs/:id for status and output
  • Chain /video/convert to standardize formats
