ToolGPT

Compress a video before you send it on WhatsApp

Tell ToolGPT the video is for WhatsApp, plus the size it has to fit if you know it. The assistant reads your video, proposes a smaller copy in a plan you can check, and makes it in your browser when you press Start.

How it works

  1. 1

    Attach the video

    Add it with the + button or drop it into the chat. On a phone, you can pick it from your photos.

  2. 2

    Say it is for WhatsApp

    Mention WhatsApp and, if you know it, the size limit you are working to. ToolGPT shows a plan with the estimated size, resolution, format and frame rate.

  3. 3

    Start, save and share

    Press Start compression and download the result. Then share it in WhatsApp as you normally would.

Why ToolGPT asks about the size

WhatsApp sets its own limits on the files you can send, and it changes them from time to time. Compression has no fixed WhatsApp setting. It works from your video's real bitrate, resolution and length, and from any size you give it. If you are not sure of the limit, check the app, then tell the assistant the number.

If your video is not already an MP4, ask for one. MP4 with H.264 video plays on almost every phone.

Sending in a chat or posting to Status

For a normal chat message, compression keeps the whole video and its shape. It lowers the bitrate, and the resolution or frame rate if you agree, so the file gets smaller without cutting anything out.

A Status update is a different job. ToolGPT has a WhatsApp Status recipe that makes a vertical 1080×1920 MP4 from up to 30 seconds of your video, fitting the whole picture into the frame. Ask for "WhatsApp Status" by name to use it.

Private videos stay on your device

Family videos are often private. The compression runs in your browser, on your phone or computer, so the video is not sent anywhere to be compressed. A long video takes longer on an older phone, and a progress bar in the chat shows how far it has got.

Frequently asked questions

What is WhatsApp's size limit?

WhatsApp sets it and can change it, so check the app. Then tell ToolGPT the number, and it plans a file below it.

Will the video be cropped or shortened?

Not by compression, which keeps the whole video and its shape. Only the WhatsApp Status recipe keeps a part of up to 30 seconds.

Does ToolGPT send the video on WhatsApp?

No. It makes the smaller file. You download it and share it yourself.

Can I do this on my phone?

Yes. ToolGPT works in a phone browser, and the compression runs in your browser there too.
