Last updated September 2026

How it works

Three steps. Nothing leaves your device.

1

Drop your video or audio

Drag a file in or tap to pick one — MP4, MOV, WebM, MKV, AVI, or MP3, M4A, WAV, FLAC, OGG. It loads into your browser, not a server.

2

Pick a size — and trim if you want

Choose a preset (WhatsApp, Email, Discord…), a bitrate for audio, or a custom size. Optionally set a start and end time to keep just one part.

3

Download the smaller file

Everything runs on your device with a live progress bar. Preview the result and download — all without a single upload.

The result

A 92 MB clip becomes a 14 MB clip.

Pick the “WhatsApp (16 MB)” preset and a 30-second 1080p clip drops from 92 MB to about 14 MB — small enough to send, still sharp enough to watch.

After · WhatsApp preset

≈ 85% smaller

Exact numbers depend on your clip — but the savings are always real, and the math always runs on your device.

Built around one principle: your video is yours, and it stays on your device.

Your video never uploads

Compression runs entirely on your device with WebAssembly. The file never leaves your browser — only the compressor's code loads from a CDN, never your video.

Free, no watermark

Every export is clean — no logo stamped in the corner, no trial limits, no “upgrade to remove watermark.” Compress as many videos as you want.

WhatsApp & email presets

One tap shrinks your clip to fit WhatsApp's 16 MB limit, Gmail's 25 MB cap, or Discord's upload size — no guessing at bitrates.

Audio too — MP3, M4A, WAV

Not just video. Shrink an MP3, M4A, WAV, FLAC, OGG or a WhatsApp voice note by picking a bitrate — 128 kbps for music, 64 kbps for voice.

Trim without re-encoding

Cut a clip to an exact start and end time. The fast mode copies the streams straight through — instant, and with zero quality loss.

No signup, no install

There's no account to create and nothing to download. Open the page, drop a video, get a smaller file. That's the whole flow.

Works offline after load

Once the compressor's code has loaded once, it's cached. You can pop offline and keep compressing — because nothing was ever being sent anywhere.

Fast H.264 output

Exports universal H.264 MP4 with +faststart so it plays instantly everywhere — phones, browsers, chat apps — and streams while it loads.

FAQ

Questions, answered.

The short version: it's free, it's private, and your video never gets uploaded. The longer version lives on the FAQ.

Is it really free?

Yes — no ads on the tool, no signup, no watermark, no premium tier. The whole product runs in your browser, so there's nothing to charge for.

Does my video get uploaded?

No. Your video is processed on your device and never leaves your browser. Only the compressor's WebAssembly code loads from a CDN — never your file.

How do I compress a video for WhatsApp?

Drop your video, tap the “WhatsApp (16 MB)” preset, and download. It fits WhatsApp's status and chat limits — without uploading it anywhere first.

Will it lose quality?

Some, like any compression — but you control the trade-off. Bigger target size = higher quality. For most clips the drop is barely noticeable.

Can I compress an MP3 or a voice note?

Yes. Switch to the Audio tab and pick a bitrate — MP3, M4A, WAV, FLAC, OGG and Opus all work, including WhatsApp voice notes. Output is MP3 or M4A.

Can I cut a clip without losing quality?

Yes — the trim tool's fast mode copies the audio and video streams straight through instead of re-encoding, so it finishes almost instantly with zero quality loss.

Shrink or cut your next file without uploading it.

Open the app, drop a video or an audio file, pick a size — or just trim it. Everything runs on your device, finishes in seconds, and the file never leaves your browser.
