  • No uploads
  • Instant results

Drop a video here or click to choose a file.

Your file is read locally and never uploaded.

How it works

  1. Choose your video

    Drop in or select a clip you own. It's read locally, nothing is uploaded.

  2. Read the details

    Resolution, aspect ratio, duration, file size, and format appear instantly.

  3. Plan your next step

    Compare against your platform's specs, then resize or compress if needed.

What the numbers mean

  • Resolution: pixel dimensions; decides sharpness and shape.
  • Aspect ratio: the frame's shape, like 9:16 or 16:9.
  • Duration: length, which matters for platform limits.
  • File size: storage used, which matters for sending and uploading.
  • Format: the container and type, which decides compatibility.

Use the results to plan

Compare what you see to your target platform's specs. If the resolution is wrong, resize with the Video Resizer. If the file is too big, shrink it with the Video Compressor. A quick check here saves time and avoids failed uploads.

Frequently asked questions

Does the checker upload my video?

No. It reads the file's metadata locally in your browser, so your video stays on your device. Nothing is uploaded or stored.

What details does it show?

File name, format (type), resolution in pixels, aspect ratio, duration, and file size, everything you need to confirm a clip meets a platform's specs.

Why should I check before uploading?

Knowing the resolution, size, and format lets you confirm a video fits the platform you're posting to, avoiding surprise cropping, slow uploads, or rejected files.

Can it read any video format?

It reads any format your browser can play, which covers MP4, WebM, MOV, and most common files. If a format isn't supported, your browser simply can't open it.

Does it work on a phone?

Yes. It runs in modern mobile browsers, so you can check a clip's details directly from your phone without installing anything.
