Compress a video without uploading

Make a big video small enough to share. Set a target size in megabytes and the tool hits it on your device, so nothing is uploaded and there is no waiting on a server.

No upload, no watermark, no sign-up

Cómo funciona

Compress a video in three steps

Shrink a video right in the browser. Drop the file, set a target size, and save the smaller clip, with no upload and no account.

Step 1: Drop your video

Choose or drag in an MP4, MOV, WebM, or MKV file. It opens right away because it stays on your device.

Step 2: Set a target size

Type a size like 25 MB, or pick a quality instead. Cap the resolution at 1080p or 720p for an even smaller file.

Step 3: Download the smaller file

Save the compressed video, ready to share. No account, no email, and no watermark.

¿Para qué sirve?

What you can do with the video compressor

Make a large clip small enough to send, by aiming for a target size in megabytes or picking a quality, all without leaving your browser.

Hit a target size

Type a size like 25 MB and the tool re-encodes your video to land near it. Cap the resolution at 1080p or 720p when you need it smaller still.

You choose the trade-off

Aim for a target size, or pick a quality level instead. Lower the resolution cap to 720p when the smallest possible file matters more than fine detail.

Compresses on your device

The whole re-encode runs in your browser with WebCodecs. Your video is never uploaded, so there is no wait on a server and nothing to leak.

PREGUNTAS FRECUENTES

Common questions about compressing video

How do I compress a video?

Open the tool, drop in your video, set a target size or pick a quality, and compress. When the smaller file is ready, save it. It all happens in your browser, so there is no upload step and no account to create.

Is it free?

Yes. The compressor is free to use, with no sign-up, no trial, and no watermark on the result.

Is my video uploaded anywhere?

No. The re-encode runs on your device with WebCodecs, so the file never leaves your browser and nothing is stored on a server.

How do I get a video under 25 MB for email or Discord?

Type 25 in the target size field and compress. If it still looks soft, cap the resolution at 720p for more headroom, then compress again.

Will compressing reduce quality?

Compression re-encodes the video at a lower bitrate, so a smaller target trades away some detail. You control the balance with the target size, the quality setting, and the resolution cap, so you can keep it sharp or push for the smallest file.

What formats can I compress?

MP4, MOV, WebM, and MKV. The output stays a standard video that plays back the way the source did.

Is there a file size limit?

There is no server limit, because nothing is uploaded. Very large files are bounded only by your device memory, but most clips compress without trouble.

Can I compress a video on iPhone?

Yes. The tool runs in your phone browser, so it works on iPhone and Android with no app to install. Pick your video, set a size, and the smaller file saves to your downloads or files.

Will it add a watermark?

Never. The output is your video at a smaller size, with no watermark and no sign-up.
